Decoding extracellular matrix corruption in tumorigenesis and tissue repair

The Chakraborty lab at Roswell Park elucidates the microenvironmental regulation of extracellular matrix (ECM) protein(s) promoting cancer progression and tissue healing aspects of regenerative medicine. 

Our cutting-edge cancer research and tissue regeneration programs investigate the in-depth molecular and biochemical mechanisms of the oncogenic and tissue-regenerative functions of the protein coding gene AGRN (Agrin).

Lab Research

How do ECM components instruct tumor development and promote tissue repair post-injury?

Dr. Chakraborty and his team study how cancer cells respond to specific ECM components by transducing mechanical inputs through defined signaling response(s).

Our long-term goal is to devise strategies targeting the ‘corrupt ECM’ components that interfere with ECM and cancer cell communications, thereby enforcing tumor-restraining capabilities.
