Pgls, also known as 6-phosphogluconolactonase, is likely involved in metabolic processes as it is related to 6-phosphogluconolactone metabolism. Its function may be significant in maintaining normal metabolic balance within cells, potentially participating in pathways related to glucose metabolism and energy production [1].

In a study related to gastric cancer, PglS was found to be significantly up-regulated. High expression of PglS was correlated with TNM staging in gastric cancer, and its overexpression predicted worse overall survival (OS) and post-progression survival (PPS) for gastric cancer patients, especially in male patients, those with lymph node metastasis, and Her-2 (-) patients. This indicates that PglS may play a role in the progression and prognosis of gastric cancer [1].

In conclusion, PglS appears to have an important function in metabolism, and its abnormal expression is associated with gastric cancer, as revealed through studies on human tissue samples. Understanding the role of PglS in gastric cancer can potentially provide new insights into the disease mechanism, which may contribute to early screening, prognostic monitoring, and the development of new treatment strategies for gastric cancer.
