The Andrew Koff Lab

Research

Andrew Koff, PhD

My laboratory has combined biochemical, molecular, cellular, and genetic approaches to investigate the roles of CDK inhibitors in differentiation, development, and cancer biology. An additional major focus of the laboratory is directed towards understanding how these gene products are regulated to accomplish these roles.

People

Andrew Koff, PhD

Molecular biologist Andrew Koff is interested in identifying the genes and and molecular mechanisms by which cells make decisions regarding their proliferative capacity after they exit from the cell cycle during therapy induced senescence and during normal development.

Disclosures

Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.

MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.

Andrew Koff discloses the following relationships and financial interests:

The information published here is a complement to other publicly reported data and is for a specific annual disclosure period. There may be differences between information on this and other public sites as a result of different reporting periods and/or the various ways relationships and financial interests are categorized by organizations that publish such data.

This page and data include information for a specific MSK annual disclosure period (January 1, 2024 through disclosure submission in spring 2025). This data reflects interests that may or may not still exist. This data is updated annually.
