How Aging Normal Cells Fuel Tumor Growth and Metastasis

It has long been known that cancer is a disease of aging, but a molecular link between the two has remained elusive. Now, researchers at the Kimmel Cancer Center at Jefferson (KCC) have shown that senescence (aging cells which lose their ability to divide) and autophagy (self-eating or self-cannibalism) in the surrounding normal cells of …

Biomarker Links Clinical Outcome with New Model of Lethal Tumor Metabolism

Researchers at the Kimmel Cancer Center at Jefferson have demonstrated for the first time that the metabolic biomarker MCT4 directly links clinical outcomes with a new model of tumor metabolism that has patients “feeding” their cancer cells.  Their findings were published online March 15 in Cell Cycle. To validate the prognostic value of the biomarker, …

New “Achilles’ Heel” in Breast Cancer: Tumor Cell Mitochondria

Researchers at the Kimmel Cancer Center at Jefferson have identified cancer cell mitochondria as the unsuspecting powerhouse and “Achilles’ heel” of tumor growth, opening up the door for new therapeutic targets in breast cancer and other tumor types. Reporting in the online Dec.1 issue of Cell Cycle, Michael P. Lisanti, M.D., Ph.D., Professor and Chair …

Leukemia Drug Reverses Tamoxifen-Resistance in Breast Cancer Cells

Taking a leukemia chemotherapy drug may help breast cancer patients who don’t respond to tamoxifen overcome resistance to the widely-used drug, new research from the Kimmel Cancer Center at Jefferson suggests. Interestingly, researchers found that tamoxifen combined with dasatinib, a protein-tyrosine kinase inhibitor, reverses the chemo-resistance caused by cancer-associated fibroblasts in the surrounding tissue by …

“How & Why” Cancer Cells Eat Us Alive

Four key studies now propose a new theory about how cancer cells grow and survive, allowing researchers to design better diagnostics and therapies to target high-risk cancer patients.  These studies were conducted by a large team of researchers at Thomas Jefferson University’s Kimmel Cancer Center.

Stromal Biomarker Predicts Advanced Prostate Cancer

The same biomarker was previously identified as a prognostic factor for breast cancer The absence of a stromal protein called caveolin-1 appears to be a marker for advanced prostate cancer and metastasis, researchers from the Kimmel Cancer Center at Jefferson and Harvard Medical School reported in Cell Cycle. There was an abundance of stromal caveolin-1 …

New Universal Breast Cancer Marker Predicts Recurrence

The marker appears to be widely applicable to all breast cancer patients, regardless of other established prognostic indicators Reporting online in the American Journal of Pathology, researchers from the Kimmel Cancer Center at Jefferson have implicated the loss of a stromal protein called caveolin-1 as a major new prognostic factor in patients with breast cancer, …
