HSPs Cancer Research Results

HSPs, Heat shock proteins: Click to Expand ⟱
Source:
Type:
Heat shock proteins (HSPs) are a diverse group of molecular chaperones that assist in proper protein folding, stabilization of proteins against aggregation, and protein trafficking. In cancer, HSPs are often overexpressed, which can help tumor cells survive the stressful conditions present in the tumor microenvironment (such as hypoxia, oxidative stress, and nutrient deprivation).

-Overexpression: Many cancers exhibit high levels of HSPs compared to their normal tissue counterparts. Overexpression of chaperones like HSP27, HSP70, and HSP90 is common in various tumors.
