Alcohol; Gene expression; Inflammatory response; mRNA; Protein; Therapeutic target

Alcohol dependence is a multifactorial inherited psychiatric disease that is difficult to diagnose and treat. Recent years have seen an increase in knowledge about molecular pathways and effect of proinflammatory cytokines on alcohol dependence. Understanding this pathology as an inflammatory condition opens the possibility of using new therapeutic agents to treat ... more

Beef fatty acid content and composition have an important effect on lipid metabolism; however, gene expression changes in response to their consumption have not been entirely explored. Thirteen candidate genes were selected according to its role in lipid metabolism and confirmed expression in PBMCs. They were studied to determine their gene expression effect in ... more

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more

This study aimed to investigate the predictability of a phenotype when using a dynamic model of cattle growth. Genotypic and phenotypic information on Nellore (Bos indicus) cattle were used in a genome-wide association analysis designed to contrast the biological interpretation of core parameters [conversion efficiency of metabolizable energy to net energy for gain (k) and adjusted final ... more

Rubus coriifolius Focke is a wild plant from the Rosaceae family. It grows in both Guatemala and Mexico. The polar extract of the aerial parts of this plant has antibacterial, anti-inflammatory, and anti-protozoal activities. These properties may explain the traditional use of this plant. In vivo and in vitro assays were used to assess the genotoxic and toxic effects of an ethanol extract of ... more

Brazil is the world's largest producer of beef cattle; however, the quality of its herds needs to be improved. The use of molecular markers as auxiliary tools in selecting animals for reproduction with high pattern for beef production would significantly improve the quality of the final beef product in Brazil. The leptin gene has been demonstrated to be an excellent candidate gene for bovine ... more

5-hydroxytryptamine receptor 1A (5-HT1AR) is closely associated with cognitive functions. Selective serotonin reuptake inhibitors (SSRIs) can protect individuals from brain damage following ischemia/hypoxia. To investigate the function of SSRIs in vascular dementia (VD), we established a rat model of VD, and observed the effect of SSRIs on the expression of 5-HT1AR mRNA and neurotransmitters. ... more

We assessed the effects of equine chorionic gonadotropin (eCG) on oocyte in vitro maturation (IVM), apoptosis, and follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), and gonadotropin-releasing hormone receptor (GnRHR) expression and mRNA levels. Cumulus-oocyte complexes (COCs) were recovered from sheep ovaries and pooled in groups, before being cultured in IVM ... more

Pieridae is a butterfly family whose evolutionary history is poorly understood. Due to the difficulties in identifying morphological synapomorphies within the group and the scarcity of the fossil records, only a few studies on higher phylogeny of Pieridae have been reported to date. In this study, we describe the complete mitochondrial genomes of four pierid butterfly species (Aporia martineti ... more
