Glycyrrhizic acid exhibits strong anticancer activity in colorectal cancer cells via SIRT3 inhibition.

Sirtuin-3 (SIRT3) has been described as a colorectal cancer oncogene and to be regulated by glycyrrhizic acid (GA). However, few studies have explored the interaction between GA and SIRT3. Therefore, in the present study, we showed that GA could significantly decrease SIRT3 protein levels in SW620 and HT29 cells in a dose-dependent manner.

Hirudin ameliorates diabetic nephropathy by inhibiting Gsdmd-mediated pyroptosis.

Our group previously reported that hirudin ameliorated diabetic nephropathy (DN) in streptozotocin (STZ)-injected rats, but the mechanism remained largely unknown. Therefore, we further explored its possible mechanism. We subcutaneously injected 5 U hirudin into STZ-induced WT mice or Gasdermin D (Gsdmd) (KO) mice daily for 12 weeks, respectively, and evaluated their kidney injury.

LncRNA TTN-AS1/miR-134-5p/PAK3 axis regulates the radiosensitivity of human large intestine cancer cells through the P21 pathway and AKT/GSK-3β/β-catenin pathway.

Radiotherapy is an important adjuvant treatment for large intestine cancer even though it does not cause any response in many patients. The present study aimed to investigate the effects of the TTN antisense RNA 1 (TTN-AS1) long noncoding RNA (lncRNA) on radiotherapy dynamics of large intestine cancer cells and to explore the underlying molecular mechanisms. TTN-AS1 expression was evaluated by reverse-transcription quantitative polymerase chain reaction, western blot, and cellular immunofluorescence, and flow cytometry analysis was used to measure apoptosis.
