Homogentisic acid metabolism inhibits papillary thyroid carcinoma proliferation through ROS and p21-induced cell cycle arrest.

Thyroid cancer is one of the most common primary endocrine malignancies worldwide, and papillary thyroid carcinoma (PTC) is the predominant histological type observed therein. Although PTC has been studied extensively, our understanding of the altered metabolism and metabolic profile of PTC tumors is limited. We identified that the content of metabolite homogentisic acid (HGA) in PTC tissues was lower than that in adjacent non-cancerous tissues.

Codelivery of triptolide and IFN-γ to boost antitumor immunity for triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a specific type of breast cancer that exhibits poor prognosis and complex tumor heterogeneity. The unique immune tumor microenvironment reveals great potential of immunotherapy in TNBC. Triptolide, a potential regulator of immune-related signaling, has shown potent antitumor activity in TNBC.

Exploration of the effect of simultaneous removal of EDCs in the treatment process of different types of wastewater.

The SPE-HPLC-MS/MS method was used to investigate the concentration distribution of nine types of estrogens in 18 locations of pollution source along the Jiuzhou River belonging to river systems in Guangdong province and Guangxi Zhuang autonomous region in China, and the estrogenic activity and potential ecological risks were evaluated by calculating the estradiol equivalency (EEQ). The results showed that the calculated estradiol equivalents (cEEQs) of wastewater treatment plants from 17 locations were all higher than 1 ng/L. To further study the removal effect of the treatment process on the estrogens, the pig breeding wastewater from P4 and the municipal wastewater from P13, as well as the black-odorous water, were sampled and surveyed during the entire process.
