Previously we found that in primary NSCLC, HSPA1 was associated with good prognosis while HSPA2 correlated with bad prognosis, suggesting possible different roles of these proteins in cancer.
Although the tumorigenic potential and prognostic applications of Hsp70 have been widely investigated, it remains unclear whether genetic variations of the human isoforms HSPA1L, HSPA1A, and HSPA1B are associated with cancer risk and prognosis.
There were significant differences in genotype and allele distributions between patients and controls for the HSP70-1G+190C polymorphisms with and without adjustment for age, gender, smoking history, drinking history and family history of cancer (p<0.05).
Impaired HSP72 stress response of Mphi in patients on haemodialysis might contribute to the observed immune dysfunction and, therefore, to the increased susceptibility to infection and malignancy.
Here we show that silencing either heat-shock cognate 70 (HSC70) or HSP72 expression in human cancer cell lines has no effect on HSP90 activity or cell proliferation.
Here, we show that Hsp70-2 depletion triggers lysosomal membrane permeabilization and cathepsin-dependent cell death and identify lens epithelium-derived growth factor (LEDGF) as an Hsp70-2-regulated guardian of lysosomal stability in human cancer.
Whereas ample experimental and clinicopathological data has implicated the major stress-inducible Hsp70-1 as a protein required for cancer cell survival, the study of the other family members has been limited by the lack of experimental tools to differentiate between the highly homologous family members.
