Morphological and genetic differences in legs of a polygamous beetle between sexes, Glenea cantor (Coleopter: Cerambycidae: Lamiinae).

The legs of insects play an important role in their daily behaviour, especially reproduction. Entomologists have performed much research on the role of the leg in different behaviours of beetles, an important group in the insect family, but relatively little has been done to study the ultrastructure and transcriptome of their legs. Hence, we systematically studied the ultrastructure and gene expression of the leg of G.

Characterization of aging cancer-associated fibroblasts draws implications in prognosis and immunotherapy response in low-grade gliomas.

Due to the highly variable prognosis of low-grade gliomas (LGGs), it is important to find robust biomarkers for predicting clinical outcomes. Aging cancer-associated fibroblasts (CAFs) within the senescent stroma of a tumor microenvironment (TME) have been recently reported to play a key role in tumor development. However, there are few studies focusing on this topic in gliomas.

Next-Generation Sequencing-Based Analysis of the Roles of DNA Polymerases ν and θ in the Replicative Bypass of 8-Oxo-7,8-dihydroguanine in Human Cells.

DNA polymerase (Pol) ν and Pol θ are two specialized A-family DNA polymerases that function in the translesion synthesis of certain DNA lesions. However, the biological functions of human Pols ν and θ in cellular replicative bypass of 8-oxo-7,8-dihydroguanine (8-oxoG), an important carcinogenesis-related biomarker of oxidative DNA damage, remain unclear. Herein, we showed that depletion of Pols ν and θ in human cells could cause an elevated hypersensitivity to oxidative stress induced by hydrogen peroxide.

Manipulation of the gut microenvironment by probiotics might improve mental health and prevent stress-related psychiatric disorders. The present study aimed to determine whether () zz-1 could prevent the occurrence of depression and its potential mechanisms using a mouse model with chronic unpredictable mild stress (CUMS).

Ferroptosis-mediated Crosstalk in the Tumor Microenvironment Implicated in Cancer Progression and Therapy.

Ferroptosis is a recently recognized form of non-apoptotic regulated cell death and usually driven by iron-dependent lipid peroxidation and has arisen to play a significant role in cancer biology. Distinct from other types of cell death in morphology, genetics, and biochemistry, ferroptosis is characterized by the accumulation of lipid peroxides and lethal reactive oxygen species controlled by integrated oxidant and antioxidant systems. Increasing evidence indicates that a variety of biological processes, including amino acid, iron, lactate, and lipid metabolism, as well as glutathione, phospholipids, NADPH, and coenzyme Q10 biosynthesis, are closely related to ferroptosis sensitivity.

Maternal exposure to life events during pregnancy and congenital heart disease in offspring: a case-control study in a Chinese population.
