Research Interests

  1. AMP-activated protein kinase (AMPK)-mediated regulation of immunometabolism in ovarian cancer.
  2. Adipocyte-ovarian cancer interaction
  3. Targeting chemo-resistance in ovarian cancer 

Research Description

The Rattan lab is centered on translational ovarian cancer research, the most lethal of gynecologic malignancies.

  1. The metabolic enzyme AMPK is a master regulator of metabolism in all living beings. It is activated by the anti-diabetic drug metformin, which is been extensively studied as a repurposed drug for treatment of various cancers, including ovarian. We have published metformin's ability to inhibit ovarian tumors. We are currently studying the pathological role of AMPK in ovarian cancer using global and site-specific AMPK knockout mice. Our recent studies indicate that absence of AMPK promotes immunosuppression creating conducive environment for immune escape resulting in aggressive ovarian cancers. Our current studies include detailing the mechanism of AMPK mediated regulation of immunometabolism and anti-tumor immunity.
  2. Elucidation and therapeutic targeting of adipose tissue and ovarian cancer interactions. Adipocytes have recently been shown to play an integral role in promotion and spread of ovarian cancer. We are interested in studying the uptake and signaling talk that occurs between the fatty acids released by the adipocytes and ovarian cancer cells, through understanding the role of novel free fatty acid receptors.
  3. We are looking at chemoresistant ovarian cancer from two aspects. First, we are dissecting the metabolic differences between chemo-sensitive and -resistant ovarian tumors. Second, we are studying the role of mito-STAT3 in chemoresistance.
