Psoriasin overexpression confers drug resistance to cisplatin by activating ERK in gastric cancer

Psoriasin, part of the S100 multigenic family, that is aberrantly expressed in a number of human tumors, is recognized as a beautiful molecular target for cancer treatment. The current study aimed to characterize the function of psoriasin in gastric cancer (GC), the connected pathways by which it plays a role in cancer development and progression, and also the aftereffect of psoriasin on cellular reaction to pre-operative chemotherapy in patients with GC. Expression of psoriasin mRNA and protein were examined using quantitative polymerase squence of events and immunohistochemistry of gastric cancer cohorts, correspondingly. Gastric cancer cell models with differential expression of psoriasin were generated using stable cell lines that overexpressed psoriasin. The in vitro biological functions from the cells as a result of psoriasin overexpression and also to chemotherapeutic agents were assessed using various cell-based assays. Psoriasin was overexpressed in patients with advanced GC, and psoriasin levels brought to poor clinical outcomes. Growing psoriasin expression in GC cell lines promoted cell proliferation, migration and invasion in vitro. In addition, psoriasin overexpression caused modifications in the amount of epithelial-mesenchymal transition-connected proteins, and activated the extracellular signal-controlled kinase signaling path. Furthermore, greater amounts of psoriasin expression were considerably connected too little reaction to neoadjuvant chemotherapy in patients with GC. Psoriasin overexpression tended to lower the sensitivity of GC cells to cisplatin, potentially by inhibiting apoptosis or growing the S-phase population. Taken together, these results indicate that FR 180204 can be a promising therapeutic target for GC treatment, along with a potential molecular marker to calculate patient reaction to pre-operative chemotherapy.
