PDCD4 (Programmed Cell Death 4) is a protein that has been studied for its role in cancer biology. It is known to function as a tumor suppressor, meaning it helps prevent the formation and growth of tumors. PDCD4 is involved in various cellular processes, including apoptosis (programmed cell death), cell proliferation, and the regulation of gene expression.
In many cancer types (such as lung, breast, colorectal, and ovarian cancers), PDCD4 expression is decreased relative to normal tissues.
– Loss or reduced expression of PDCD4 is frequently observed at the mRNA and protein levels in tumor samples.
