In order to develop targeted strategies for combating drug resistance it is essential to understand it's basic molecular mechanisms. In an exploratory study we have found several possible indicators of etoposide resistance operating in MCF7VP cells, including up-regulation of ABC transporter genes, modulation of miRNA, and alteration in copy numbers of genes.

Bone marrow stimulation treatment by bone marrow stromal cells (BMSCs) released from the bone medullary cavity and differentiated into cartilage via microfracture surgery is a frequently employed technique for treating articular cartilage injuries, yet the treatment presents a main drawback of poor cartilage regeneration in the elderly. Prior research indicated that aging could decrease the stemness capacity of BMSCs, thus we made a hypothesis that increasing old BMSCs (OBMSCs) stemness might improve the results of microfracture in the elderly. First, we investigated the correlation between microfracture outcomes and BMSCs stemness using clinical data and animal experiments.

Thanks to the identification of crucial molecular pathways, the therapeutic landscape for advanced differentiated thyroid tumors (DTCs) has significantly improved during the last ten years. The therapeutic scenario has been greatly impacted by the discovery of mutually exclusive gene changes in the MAPK and PI3K/AKT pathways, such as or fusions and pathogenic mutations of the and genes. Indeed, multi-kinase inhibitors and selective inhibitors have demonstrated outstanding efficacy for radioactive iodine-refractory (RAI-R) drug treatment, with overall response rates reaching up to 86%.

Oil palm () yield is impacted by abiotic stresses, leading to significant economic losses. To understand the core abiotic stress transcriptome (CAST) of oil palm, we performed RNA-Seq analyses of oil palm leaves subjected to drought, salinity, waterlogging, heat, and cold stresses. A total of 19,834 differentially expressed genes (DEGs) were identified.
View Article and Find Full Text PDF, the most common non-viral sexually transmitted parasite, causes more than 270 million infections annually. The infection's outcome varies greatly depending on different factors that include variation in human immune responses, the vaginal microbiome, and the inherent virulence of the strain. Although the pathogenicity of the different strains depends, at least partially, on differential gene expression of virulence genes; the regulatory mechanisms governing this transcriptional control remain incompletely understood.
View Article and Find Full Text PDFThe integration of conventional omics data such as genomics and transcriptomics data into artificial intelligence models has advanced significantly in recent years; however, their low applicability in clinical contexts, due to the high complexity of models, has been limited in their direct use inpatients. We integrated classic omics, including DNA mutation and RNA gene expression, added a novel focus on promising omics methods based on A>I(G) RNA editing, and developed a drug response prediction model. We analyzed 104 patients from the Breast Cancer Genome-Guided Therapy Study (NCT02022202).
