- 1. Fatty acid (FA) composition determines the nutritional value of duck meat. Systematic characterisation of FA profiles in indigenous breeds, such as the certified Kaijiang Sheldrake, is essential for genetic improvement of meat quality.2. This study used gas chromatography-mass spectrometry (GC-MS) to comprehensively analyse the fatty acid composition in the breast muscle of 60 Kaijiang Sheldrake ducks and explored their potential genetic basis using genome-wide association analysis (GWAS).3. The GC-MS detected 51 FA, with saturated FA (SFA) accounting for the largest proportion (49.45%). Palmitic acid (C16:0, 27.96%), stearic acid (C18:0, 19.95%) and linoleic acid (C18:2n-6, 13.74%) were the most abundant. ω-3 and ω-6 polyunsaturated FA (PUFA) showed strong intra-series correlations. Several individual FA showed significant associations with phenotypic traits, including positive correlations with breast muscle weight and percentage ( < 0.05), whereas short-chain SFAs (C6:0, C13:0) and specific PUFA (C20:3n-3, C20:5n-3) were negatively associated with post-mortem pH (0 h). In contrast, no significant associations were detected between aggregated ω-3 and ω-6 indices and most slaughter or meat quality traits. GWAS further suggested potential associations for both saturated and unsaturated FA, identifying candidate genes, such as , , , , , and located near associated loci, with enrichment in metabolic pathways including carbohydrate metabolism and glycolysis.4. Overall, this study systematically evaluated slaughter performance, meat quality traits and the fatty acid composition of breast muscle in Kaijiang Sheldrake, providing comprehensive data to support the utilisation and precision breeding of local duck genetic resources. - Source: PubMed

Yang ZRen JWang LLi LBai LPeng DZhou FZeng XLi YLiao YHu BLiu H - Osimertinib has emerged as a critical element in the treatment landscape following recent clinical trials. Further investigation into the mechanisms driving resistance to Osimertinib is necessary to address the restricted treatment options and survival advantages that are compromised by resistance in patients with EGFR-mutated lung adenocarcinoma (LUAD). - Source: PubMed

Sun DantongHou HeleiFeng FeiyueWu WeizhengTan JingyuXie TongjiLiu JiayuWang JinsongQian HailiLi JunlingXing Puyuan - Breast cancer (BC) comprises multiple subtypes with distinct molecular features, which differ in their interplay with host immunity, prognosis, and treatment. Non-invasive blood analyses can provide valuable insights into systemic immunity during cancer. The aim of this study was to analyze the expression of transcriptional isoforms in peripheral blood mononuclear cells (PBMCs) from BC patients and healthy women to identify potential BC immune biomarkers. RNA sequencing and isoform-level bioinformatics were performed on PBMCs from 12 triple-negative and 13 luminal A patients. Isoform expression validation by qRT-PCR and clinicopathological correlations were performed in a larger cohort (156 BC patients and 32 healthy women). Transcriptional analyses showed a significant ( < 0.001) decrease in the isoform in PBMCs of BC compared to healthy subjects, indicating disease-related expression changes. The decrease was associated with higher ctDNA and Ki-67 values. The levels of the transcriptional isoform may have the potential to distinguish between BC and healthy subjects. The downregulation of in breast cancer is associated with higher proliferation and ctDNA shedding. Specialized bioinformatics analyses such as isoform analyses hold significant promise in the detection of biomarkers, since standard RNA sequencing analyses may overlook specific transcriptional changes that may be disease-associated and biologically important. - Source: PubMed

Total hip or knee arthroplasty is the most effective method to treat OA. However, severe postsurgical pain leading to a poor prognosis. So, investigating the population genetics and genes related to severe chronic pain in older adult patients after lower extremity arthroplasty is helpful to improve the quality of treatment. - Source: PubMed

Xu RuiJin YinanTang SuhongWang WenwenSun Yu-ELiu YueZhang WeiHou BailingHuang YulinMa Zhengliang - Acute myeloid leukemia (AML) is a significantly heterogeneous malignancy of the blood. Cytogenetic abnormalities are crucial for the prognosis of AML. However, since more than half of patients with AML are cytogenetically normal AML (CN-AML), predictive prognostic indicators need to be further refined. In recent years, gene abnormalities are considered to be strong prognostic factors of CN-AML, already having clinical significance for treatment. In addition, the relationship of methylation in some genes and AML prognosis predicting has been discovered. RASGEF1A is a guanine nucleotide exchange factors of Ras and widely expressed in brain tissue, bone marrow and 17 other tissues. RASGEF1A has been reported to be associated with a variety of malignant tumors, examples include Hirschsprung disease, renal cell carcinoma, breast cancer, diffuse large B cell lymphoma, intrahepatic cholangiocarcinoma and so on [1, 2]. However, the relationship between the RASGEF1A gene and CN-AML has not been reported. - Source: PubMed
