Yaffe Finds New Target for Cancer Combination Treatment

Mutation of the p53 gene occurs in about half of all cancer patients, and tumors with the mutation continue growing even after intense chemotherapy. Previously, the lab of Michael Yaffe, David H. Koch Professor of Biology and Biological Engineering, discovered that blocking a gene called MK2 can overcome the effects of the p53 mutation and make these tumors more vulnerable to chemotherapy in vitro. In a new study published in Cell Reports, Yaffe lab researchers collaborated with KI Director Tyler Jacks to create mice with MK2 genes that can be turned on and off and test the process in vivo. They found that in p53-deficient tumor-bearing mice with MK2 turned off, tumors shrank successfully upon treatment with the DNA-damaging therapeutic cisplatin, whereas tumors in mice with unblocked MK2 genes continued growing. This study suggests potential for new cancer treatments combining MK2 inhibitors with DNA-damaging drugs. Drugs that inhibit MK2 are in the works for other diseases such as arthritis, but this is the first time they are being considered for cancer therapy. The research was primarily funded by a TRANSCEND grant from Janssen Pharmaceuticals, Inc.
 
The study was profiled in MIT Technology Review. more...

Yaffe Attempts Special Engineering Feat For KI

Michael Yaffe, David H. Koch Professor in Biology and Biological Engineering, is a notable biologist, engineer, entrepreneur, physician, military trauma surgeon, and dad. On September 16, 2013 from 6-8PM, Professor Yaffe will publicly test whether all his skills are enough to construct that biologically heterogeneous, composite-layered cylindrical marvel known as the burrito. Yaffe will roll as part of the Anna's Taqueria Celebrity Burrito Roller Series at Anna's MIT location in the Stratton Student Center. Burritos are $10 each, with the full amount going to benefit KI programs and research.  This may be the tastiest way ever to support the KI! more...

Sequence Matters: mTORC1 Phosphorylation Sites and Rapamycin

The drug rapamycin, a partial inhibitor of the kinase subunit of the protein complex mTORC1, can slow cancer cell growth and prolong life span. In a new Science publication, a collaborative team led by KI members David Sabatini and Michael Yaffe shows that the characteristics, including sequence composition, of the sites that are phosphorylated by mTORC1 determine how efficient the phosphorylation is and the sensitivity of the process to rapamycin inhibition and starvation within cells; the more efficient the phosphorylation, the more resistant it is to rapamycin inhibition and starvation.  These results may explain the weak efficacy of the drug in several early cancer clinical trials. more...

Staggered Drug Delivery Shows Promise in Treating Aggressive Breast Cancer

KI member Michael Yaffe and his laboratory team report finding, in the May 11 issue of Cell, that staggering the doses of two common cancer drugs dramatically boosts their ability to kill a particularly malignant type of breast cancer cells. Yaffe has been studying the complex cell signaling pathways of cancer cells and the ability of dysfunctional pathways to promote uncontrolled cell growth. He is now working with researchers at Dana Farber Cancer Institute to plan clinical trials of the novel approach. more...

Tumor mutations can predict chemo success

New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy. The findings should have an immediate impact on cancer treatment, say Michael Hemann and Michael Yaffe, the two MIT biology professors who led the study. The work could help doctors predict what types of chemotherapy will be effective in a particular tumor, which would help tailor treatments to each patient. more...

New KI computational models to individualize cancer treatment

In Cell, KI researcher describe how computer simulations can reveal the inner workings and vulnerabilities of a cancer. The results reveal new ways in which cells process chemical information and could indicate how to maximize the effectiveness of disease treatments such as chemotherapy. more...
