Abstract Mutations that inactivate negative translation regulators cause autism spectrum disorders (ASD), which predominantly affect males and exhibit social interaction communication deficits repetitive behaviors. However, the cells ASD through elevated protein synthesis resulting from these mutations remain unknown. Here we employ conditional overexpression of initiation factor eIF4E to increase in specific brain cells. We show exaggerated microglia, but not neurons or astrocytes, leads...

Abstract Chemotherapy is a primary treatment for esophageal squamous cell carcinoma (ESCC). Resistance to chemotherapeutic drugs an important hurdle effective treatment. Understanding the mechanisms underlying chemotherapy resistance in ESCC unmet medical need improve survival of ESCC. Herein, we demonstrate that ferroptosis triggered by inhibiting high mobility group AT-hook 1 (HMGA1) may provide novel opportunity gain therapeutic strategy against chemoresistance HMGA1 upregulated and works...

Abstract Caspase-2 is the most evolutionarily conserved member in caspase family of proteases and constitutively expressed cell types including neurons; however, its physiological function remains largely unknown. Here we report that caspase-2 plays a critical role synaptic plasticity cognitive flexibility. We found deficiency led to deficits dendritic spine pruning, internalization AMPA receptors long-term depression. Our results indicate degrades Rictor, key mTOR complex 2 (mTORC2)...

Anxiety disorders are associated with body weight changes in humans. However, the mechanisms underlying anxiety-induced remain poorly understood. Using Emx1Cre/+ mice, we deleted gene for brain-derived neurotrophic factor (BDNF) cortex, hippocampus, and some amygdalar subregions. The resulting mutant mice displayed impaired GABAergic transmission elevated anxiety. They were leaner when fed either a chow diet or high-fat diet, owing to higher sympathetic activity, basal metabolic rate, brown...

Deficiency in T cell-mediated adaptive immunity, such as low CD8+ cell infiltration, inhibits the immune surveillance, promotes malignant transformation, and facilitates tumor growth. Microbiota dysbiosis diminishes system contributes to occurrence of cancer. However, impact oral on molecular mechanisms oropharyngeal cancer (OPC) remains largely unknown. In current study, we used 4-nitroquinoline-1-oxide (4NQO) mimic tobacco-related carcinogenesis generate a murine OPC model determine role...

Abdominal irradiation (IR) destroys the intestinal mucosal barrier, leading to severe infection. There is an urgent need find safe and effective treatments reduce IR-induced injury. In this study, we reported that metformin protected mice from abdominal injury by improving composition diversity of flora. The elimination microbiota (Abx) abrogated protective effects on irradiated mice. We further characterized treatment increased murine abundance Lactobacillus, which mediated radioprotective...

Abstract Objective To evaluate the cognitive function of Chinese patients with Parkinson's disease PD postsubthalamic nucleus deep brain stimulation (STN‐DBS). Methods Cognitive was assessed by neuropsychological methods in patients. Twenty matched healthy persons served as normal controls. t test, analysis variance, and chi‐square were used to compare difference among groups. Reliable change index utilized analyze changes cognition from individual level. Results (a) Improvement motor...

As loss of DNA-repair proteins is common in urothelial carcinoma (UC), a rationale can be made to evaluate the activity poly (ADP-ribose) polymerase (PARP) inhibitors exploit synthetic lethality. We aimed preclinically PARP inhibitor, CEP-9722, and its active metabolite, CEP-8983, UC. The CEP-8983 was evaluated using 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay against human UC cell lines. Flow cytometry, COMET assay, western blot were performed assess apoptosis,...
