Cancer is one of the leading causes of death in North America today. The Canadian Cancer Society estimates that in 2009 alone, 171,000 Canadians will be diagnosed. While there is no cure yet, a recent discovery at U of T Mississauga may give chemotherapy an added edge in the ongoing battle with this disease.Patrick T. Gunning, professor in the Department of Chemical and Physical Sciences at UTM, is currently working with scientists at the University of Central Florida and Princess Margaret Hospital to improve the treatment of human cancers.STAT3 (Signal Transducer and Activator of Transcription 3), a protein present in cancer cells, causes drug therapy resistance when it pairs up with another copy of itself. Gunning and his team have developed a way to break apart this cancer protein pair, to possibly increase the effectiveness of chemotherapy. His research team has successfully developed inhibitor molecules that work to stop STAT3 protein activity.“We have managed to develop small molecules that target STAT3–STAT3 protein complexes” said Gunning. Targeting the protein-protein interactions of STAT3 disrupts the protein’s biological function.Increased STAT3 activity is observed in multiple human cancers and plays a key role in cancer progression. In healthy individuals, STAT3 activity is transitory and highly regulated, lasting only a couple of minutes to a couple of hours. However, in cancer cells STAT3 is for some reason permanently activated, resulting in the expression of genes that promote cancer growth, survival, and differentiation.Gunning’s research team is currently working to increase the stability and effectiveness of the STAT3 inhibitor molecules. “Our global objective is to develop novel molecular therapeutics to target human cancers. In particular, our research has focused on targeting protein-protein interactions—a particularly difficult medicinal challenge,” Gunning explained.Traditional chemotherapy induces cell death in both healthy and cancerous cells, resulting in devastating side effects. Gunning’s preliminary STAT3 inhibitors display impressive selectivity for cancer cells over healthy cells, and hold promise for improving the effectiveness of chemotherapeutic techniques.The team’s discovery highlights the importance and targetablity of protein-protein interactions. Gunning explained, “Despite the important role STAT3 plays in biological function, targeting protein–protein interactions is still regarded as high-risk. We want to illustrate through our molecular therapeutics that these important interactions are targetable and that a greater effort should be made on investigating them. STAT3 protein-protein interactions should be targeted because, if successful, the potential benefits are huge.”Lead inhibitor compounds are now in pre-clinical trials. Gunning hopes that knocking out STAT3 will make cancer cells more susceptible to antineoplastics, thus reducing the dosage required and subsequently lowering the adverse side-effects associated with aggressive chemotherapy.The results of this study can be found in the September issue of ChemBioChem: A European Journal of Chemical Biology.
UTM breakthrough could reduce chemo side effects
As the afternoon closed on Varsity Stadium, Saturday had an unjustly indecisive air for both men’s and women’s Varsity Blues soccer as they came out of what was supposed to be a double-header against the Carleton Ravens.“Unjust” because both teams are looking strong in the early season.With the women’s team now 3-0-2 to Carleton’s 2-4-2, it would be reasonable to expect the Blues were anticipating their early-afternoon game until it was cancelled. As was later reported, Carleton suspended the women’s team the day before the game after the team broke the university athletics department’s code of conduct by holding a rookie initiation party where drinking was so excessive that one player was taken to hospital by ambulance. At game time, however, no explanation had been given to Varsity Athletics.The men’s game, which did go ahead, was a more even match. It’s early going still, but the Blues are ranked second in the OUA East, and the Ravens, third. However, the reality on the field—that the Blues dominated for the majority of the play—didn’t translate to the board, with the game ending in a scoreless draw.That it did end nil-all speaks to the strength of the Ravens defence, and especially goalie Samuel Hincks, who often had to step into the front-of-net maelstrom, smother the ball, and launch it midfield, only to have it returned to him shortly after. But Carleton showed trouble throughout the game with ball control. As one Blues fan and Ravens heckler noted, you’re supposed to keep the ball off the blue track that surrounds the field.The Blues, by comparison, were all offense. Fourth-year striker Nordo Gooden’s fancy footwork set the game’s tone—and the fans’ hopes—early on as he showed the Ravens how it’s done, practically dancing the ball down the touchline. Gooden was a clear fan favourite of the game along with second-year midfielder Geoffrey Borgmann, who showed ease turning around an opposing play even while in a crowd.The Ravens did bring their game back in the second half, though with the play waning on, it was clear the offense became increasingly frustrated. By the end of the second, Carleton had been issued three yellow cards to Toronto’s one, all of which were earned as players lost control in what were otherwise good aggressive maneuvers.This isn’t to say that the Blues didn’t make their own mistakes. Their offensive strength didn’t count where it had to: on the scoreboard. Sloppiness at points showed a lack of focus and drive. Early in the second, Toronto narrowly avoided what could have become a heartbreaking own-goal as what appeared to be a daydreaming Scott Nesbitt passed to goaltender John Smits, who, caught unawares, was left scrambling to keep the ball on the right side of the goal line. The clearly shaken Smits didn’t appreciate the lack of communication from his teammate, as everyone in the stands heard.The payback in sports usually comes only after a lot of legwork. On Saturday, the Blues did a lot of legwork, but once they got to the decisive moment, pulled back. With five minutes to go, the game could have been theirs after Gooden was scuffed by a Carleton defender in the penalty area, earning Toronto a penalty kick. But midfielder Vlejko Lukovic’s attempt soared so high over the cross bar, you had to wonder, did the Blues want it after all?
Blues lose, but remain optimistic
The Varsity Blues women’s rugby team hosted the McMaster Marauders at the University of Toronto’s Back Campus last Saturday. The Blues put up a strong defensive front, but were defeated 27-0. The Blues were able to demonstrate their skills in the second half, however, revealing that they boast many talented players on their roster.The game got off to a decisive start when the Marauders scored their first try in the opening minutes. They quickly followed it up with four more tries and one conversion, bringing the score to 22-0 in only 40 minutes. The Marauders dominated the scrums thanks to strong forwards, and were quick to get the ball out to their wing line, who fed it down in a series of clean passes.As the game progressed, U of T remained resilient. “We really gave it to them in the second half,” said Blues co-captain and hooker Sonya Kuwiz. The Blues tightened up their defence and began to react faster to the Marauders’ attempts to score. They caught onto Marauders’ eight-man Natasha Turner, and her repeated efforts to pick the ball from the scrum.The Blues’ backs reorganized so that co-captain Hannah Ehrhardt remained at fly half, followed by centres Silvana Skoko and Charlotte Cooper, and Jana Davis moved to the wing. Gwen Kern continued to play strong as the Blues’ fullback. Although it was only a slight reconfiguration of the field, it proved incredibly advantageous. The backs worked well together to move the ball fluidly when they received it from scrum half Sarah Stainton, and were aggressive in their attempts to take advantage of the play.The entire team was determined to stave off attempted tries by McMaster. The Marauders scored only one more try in the second half of the game—the result of an unexpected breakaway during the last five minutes of play.Last season the Marauders played a close semi-final game against the 2008 OUA Champions Guelph Gryphons, losing by only 16 points. More recently, on Sept. 12, they blanked the York Lions 43-0. McMaster is recognized as a strong team and consequently the small margin of victory they had over the Blues is viewed with optimism. Head coach Shannon Smith was in positive spirits post-game and admitted that she was very proud.The roster this season is composed primarily of new players—only 15 out of the 33 are returning from 2008. Although mostly rookies, the team demonstrates a lot of potential: they may just need a little bit more time to feel each other out. “[The women are working] to start playing as a team and get the cohesion up,” said co-captain Ehrhardt.The season is short, but Ehrhardt has faith. One thing she hopes the team can accomplish this year is to make the playoffs.The game against the Marauders proved that the Blues are more than capable of becoming a top-ranked team in the future. They displayed an abundance of talent from both the returning players and the newer members. Veteran Kern produced some near impossible catches as fullback, in addition to the fantastic tackles she made to stunt the Marauders mid-breakaway. Stainton, who was not on last year’s team, was aggressive and quick to react. She entered the game near the end of the first half, and within seconds had intercepted the ball, giving the Blues the advantage.With the help of fan support, the team will be able to step it up a notch and reach their full potential.

The Wall Street Journal recently published a piece about several laid-off workers from the business sector, entitled “Where They Are Going.” It told tales of high-paid financial workers converting their sudden unemployment into a chance to turn a new leaf, find themselves, and start over. One such six-figure man suffered a six-month stint as a truck driver—a job he could not bear to return to—while two others used their savings to find their calling driving another type of vehicle: a Mister Softee ice cream truck. As I read about incredibly wealthy people taking unemployment as a way to return to a simpler life, my thoughts on what was supposed to be an uplifting article shifted to only one expression: fuck off.The reality of the recession was best reported by The New York Times last Friday in their piece on the boomers, or “Generation B.” While high-paid executives are finding a new lease on life, the economic downturn has devasted regular folk. The generation of our parents, aged 45 to 65, now has the highest suicide rate of all age groups. “It’s hard to maintain your focus that you’re a valuable member of society when you go three months and nobody really wants to employ you,” 59-year-old David O’Bryan of Barre, Vt. told Time. It’s no surprise that according to the U.S. Federal Suicide Prevention Resource Center web site, “widespread increases in unemployment” are “strongly linked with increases in suicide rates.” Even those who have work face the constant stress of looming job cuts and the fear of “Will I be next?”Here’s a generation that grew up thinking that success came from hard work and finding a stable job. And for a while, most of them had that success. They had jobs, they had houses, and they had stability—until the summer of 2008, when it all began to fall apart.While Federal Reserve chairman Ben Bernanke declared last week that the recession “is over,” the jobless rate in the U.S. is still at a 26-year high. New York City now faces unemployment above 10 per cent, and the U.S. overall is at 9.7 per cent. That means roughly one in ten Americans that would like to work is unemployed. Ask around, and it won’t be hard to find students with unemployed parents. The boomers aren’t just losing their jobs, but also their houses. Two weeks ago, Bloomberg reported that foreclosure filings in the U.S. exceeded 300,000 for the sixth straight month. Sure, a lack of income can be weathered out with unemployment insurance and savings, but that can only last so long. Though the U.S. government and banks are trying to modify mortgage payments to prevent foreclosures, the climbing jobless rate is making that impossible.According to the Organization for Economic Cooperation and Development, jobless rates will likely remain high for years to come. In fact, job prospects have been so bleak that the United States’ discouraged worker rate—also known as persons of legal employment age who are not actively seeking employment—reached 758,000 in August, doubling from last year. That’s not even including the PhDs who have taken on part-time jobs, or other such cases of underemployment.Unemployment is a lagging indicator of economic growth. The OECD explains that recovery will be slow, due to how quickly and severely the recession began. As I explained in my last column, New York University prof Nouriel Roubini and Nobel Prize–winning economist Joseph Stiglitz fear the economy will either recover very slowly, or dip back into a deeper recession, bouncing back later. Even the optimistic option is bad for morale.Regarding the six-figure workers who “found themselves,” I feel badly about getting so enraged at their happiness. But the sentiment remains. Yes, losing your job allows you to take a look at who you are and reconsider your career options. But for far too many, losing your job is a nightmare you can’t wake up from—at least according to current economic forecasting—for several years.
You have three law school requests
Think contacting an admissions officer on Facebook will add a novel twist to your application? You’re not the only one. According to a survey by the test prep company Kaplan, admissions officers at half of surveyed U.S. business schools, 48 per cent of law schools, and 31 per cent of medical schools say they have received friend requests from prospective students on Facebook.In addition, more schools have started to take advantage of sites like Facebook and the wealth of information that they can provide. This year, 21 per cent of schools say they have begun to develop admissions policies for social networking sites, up from 16 per cent last year.“College applicants these days are seeking any competitive edge they can,” Jeff Olson, executive director of research at Kaplan, told Reuters. “For now, only a small number of college admissions officers actually visit applicants’ social networking sites, and these visits may not always benefit the applicant.”Source: Reuters
Hit the road, Jack!
“Canada’s political tides have shifted away from an election,” wrote Luke Savage in the last issue of The Varsity. While it may be true that an election has been postponed, there has been no shifting of political tides, only a selling-out of progressive principles by Jack Layton and the NDP.The NDP’s decision to prop-up the government was neither about extracting concessions on Employment Insurance—which even the party’s president, Peggy Nash, admitted were “absolutely not enough” – or about co-operation to “make Parliament work.” It was a cold-blooded political calculation made by a party and leader that reeks of the worst kind of opportunism. It is a pathetic distillation of the long-held belief of many Canadians that the NDP no longer stands for progressive policies, only posturing.Let’s be clear. The New Democrats are in no position to fight an election in today’s political climate. They have no money, while campaigns are increasingly expensive; the Liberals and Conservatives are out-fundraising the NDP by huge margins. Many NDP MPs have been sitting for only a year—making them extremely electorally vulnerable—they have barely nominated 10 per cent of their candidates nationally, and they face an invigorated Liberal Party that is no longer led by Stéphane Dion. Most importantly, New Democrats have no idea what their own party stands for.Led by their moustachioed firebrand leader, the NDP has smugly proclaimed for months that they would oppose the Harper government, final stop. They would proudly vote against the Harper budget without even reading it. They would proudly oppose the economic update in June. On all matters of confidence, the NDP would vote against the government. But alas, they did not.This isn’t the first time the New Democrats have joined the Conservatives and the Bloc Quebecois. In November 2005, Jack Layton proudly brought down the Paul Martin government, bringing on the election that got Stephen Harper his first term as prime minister. Then, as now, Jack put politics over principles.But now more than ever, the NDP should be standing by their principles to guard against the further crumbling of Canada’s ideals. In his few years as Prime Minister, Stephen Harper has changed this country’s political landscape. Little by little, he’s dismantling our hard-won national institutions. He’s reversing years of progress that Canada has made in international affairs, and he has shown a disdain for national unity, favouring a politics of division and deceit. Enough is enough.But on Friday, the New Democrats rose ceremoniously in support of the Harper government. They expressed their confidence in the policies of the Harper Conservatives, and ensured the government’s continued survival.This blatant selling-out of deeply held policy beliefs of the party and its core supporters is not just offensive to political observers. It affects the state of this nation. The result of Layton’s calculations back in 2005 was the cancellation of national childcare, the abandonment of our commitment to the Kyoto Protocol, and the destruction of the Kelowna Accord, a hard-won policy for support and development in Aboriginal communities across the country.Especially in a parliamentary democracy, it is crucially important to hold our representatives accountable for their actions. The NDP purports to be Canada’s progressive conscience. How can this be so when Jack Layton, Olivia Chow, and the rest of the NDP caucus show that time and again, they are willing to sacrifice their principles to please the pollsters?Students here at the University of Toronto are right to be cynical about our political system. Having elected Olivia Chow to Parliament to stand up for them as representative for Trinity-Spadina, what they got was a professional politician who betrayed them last Friday by ensuring the continued survival of the Harper government. She, like Jack Layton, put politics before principles. But students are catching on to Layton’s ruse. The NDP is in danger of losing the riding of Trinity-Spadina, which includes most of U of T. And quite frankly, they should lose it. They have failed to stand up for progressives on this campus and across the country. As it turns out, the only thing the NDP stands up for is Stephen Harper’s government.It’s one thing to talk about putting politics before principles in the abstract way that pundits like to analyse politics. It’s quite another to consider the very real, very destructive consequences of Layton’s calculations. He abandoned progressive Canadians when he stood with Harper in 2005, and he did it again on Friday.
Nova Scotia entices grads to stay home
Nova Scotia is introducing a graduate tax incentive that will offer community college and university graduates up to $15,000 in order to keep skilled young people in-province. Although it is the second-smallest province in Canada, Nova Scotia’s university enrollment per capita is the highest. The Memorandum of Understanding on University Funding and Tuition Fees has also announced its plans on freezing tuition fees for university students for the 2010-2011 academic year. Working closely with post-secondary institutions, the government also plans to make the best use of the Nova Scotia Crown Share University Infrastructure Trust Fund.Source: Throne Speech from Sept. 17, 2009
