Dr. Sultana has investigated the roles of mitochondrial pyruvate carrier MPC1 and MPC2 in metabolism and their relationship with various diseases such as diabetes and obesity. In her Ph.D. project she explored the roles of mammalian ubiquitin ligases UBR1, UBR2, and CHIP in protein degradation that are related to the development of cancers. She also explored the action of UBR1 in the degradation of nuclear receptors such as glucocorticoid receptor (GR), androgen receptor (AR), and estrogen receptor (ER). She has research experience in identification of most prevalent genotype in rotavirus for vaccine development.
Her research interests include cytosolic and mitochondrial protein quality control and underlying molecular mechanism for the development of various diseases.
