Leptin is a small protein hormone that controls satiety and is produced by adipocytes. Obese people have increased levels of circulating leptin. Excessive leptin levels cause a break down in the control of leptin signaling pathways leading to increased angiogenesis, proliferation, cell migration, invasion, and anti-apoptotic events. Obesity and leptin signaling have been linked to cancer progression. Literature shows that LPrA2 is an effective leptin antagonist as it decreases proliferation of breast cancer cells in vitro.

This project compares the effectiveness of LPrA2 like compounds in breast cancer cell-line MDA-MB-468 (M-468 BCs). We hypothesize that the new peptide antagonists have ...

Breast cancer is a malignant growth in the adipose-rich mammary gland. Initiation and progression of breast tumors involve multiple cell types, among which mammary cancer stem cells play an important role. There are two main types of adipocytes; white adipocytes have previously been found to influence the disease while brown adipocytes, which uniquely express uncoupling protein 1 (UCP1), were recently detected in breast tumors.

We have detected Myf5, a transcription factor, which is expressed in the progenitor population of brown adipocytes, in breast cancer cell lines. We also found an association between expression of Myf5 and COX2 (or Ptgs2), which ...

Breast cancer remains a complex disease that kills 40,000 women every year. Initiation and progression of breast cancer is influenced by heterogeneous groups of cells, including mammary cancer stem cells (MCSCs). Progression of this dreadful disease is driven by many signaling pathways among which MAPK pathway is highly prominent. Since targeting prominent kinases in MAPK pathway has been unsuccessful to control breast cancer, it is important to examine the phosphatases that regulate the activity of these kinases.

Using xenograft model from breast cancer cell lines, our lab has found that during the initial stages of xenograft development (week 1-4 ...
