Salivary Adenoid Cystic Carcinoma (SACC) is a tumor characterized by inevitable local progression and terminal hematogenous metastasis. This study aimed to investigate the expression of LC3, LAMP2, KEAP1 and NRF2 in SACC. Human salivary gland tissue microarray which contains 74 SACC, 12 pleomorphic adenoma and 18 normal salivary gland specimens. High expression of LC3, LAMP2, KEAP1 and NRF2 were found in SACC patients, and LC3, LAMP2, KEAP1 and NRF2 expression were significantly higher in SACC than as compared with pleomorphic adenoma and (or) normal salivary gland. The expression of NRF2 was correlated with pathological type of human SACC (P < 0.05). Moreover, the high-expression of KEAP1 had significant correlations with LC3 (P < 0.001, R = 0.3195), and LAMP2 (P < 0.001, R = 0.3346) and NRF2 (P < 0.05, R = 0.2246) by using the Pearson correlation coefficient test. Our findings demonstrated that up-regulation of LC3, LAMP2, KEAP1 and NRF2 were associated with carcinogenesis and progression of SACC patients, suggesting that they may be useful molecular targets in salivary adenoid cystic carcinoma.

The disease burden of renal cell carcinoma (RCC) has decreased in recent years with advances in treatment, but its pathogeny still remains elusive. We aim to study the role of HOXA3/USP15/SQSTM1 axis on autophagy and M2-type macrophage polarization in RCC. In this study, cell apoptosis and proliferation were assessed by flow cytometry and CCK-8.

Recently we proposed the possibility of orally exposed nanoparticles (NPs) to alter metabolite homeostasis by changing metabolism pathways, in addition to intestinal damages, but relatively few studies investigated the changes of metabolite profiles in multi-organs. This study investigated the influences of orally exposed SiO NPs on lipid profiles in gut-liver axis. To this end, we treated mice with 16, 160 or 1600 mg/kg bodyweight SiO NPs via intragastric route.

Tyrosine phosphatase SHP2 promoted the progression of CRC via modulating the PI3K/BRD4/TFEB signaling induced ferroptosis.

Department of General Surgery, Bethune International Peace Hospital of The People's Liberation Army, No. 398, Zhongshan XI Road, Qiaoxi District, Shijiazhuang, 050000, Hebei, People's Republic of China.

Objective: To elucidate the mechanism by which tyrosine phosphatase SHP2 protects CRC through modulation of TFEB-mediated ferritinophagy, thereby suppressing ROS and ferroptosis.

Methods: SW480 and SW620 cells, in the logarithmic growth phase, were treated with or without the SHP2 inhibitor PHPS1, the activator Trichomide A, EGF, or MMP inhibitors, and randomly assigned to four groups. Additionally, SW480 cells in the logarithmic phase underwent treatments with EGF, the ferroptosis inducer erastin, Trichomide A, or the curcumin analog C1, forming seven groups.

To investigate the mechanism of pancreatic alveolar cell autophagy in rats with severe acute pancreatitis (SAP) by phillygenin (PHI) based on the PI3K/Akt/mToR pathway. Rats were randomly divided into control group (CON group), SAP model group (SAP group) and PHI treatment group (SAP+PHI group), with 10 rats in each group. 5% sodium taurocholate was injected retrogradely into the biliopancreatic duct to establish a SAP rat model, and PHI was injected intraperitoneally into the pancreas after successful establishment of the model.

Ovarian dysfunction caused by aging restricts female reproductive capacity and is accompanied by oxidative stress and impaired autophagy. Recent studies have shown that trehalose (Tre) can activate autophagy and have antioxidant effects. However, whether Tre can be used to attenuate ovarian aging remains unclear.
