Gene expression analysis through reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) depends on correct data normalization by reference genes with stable expression. Although NRRL B-598 is a promising Gram-positive bacterium for the industrial production of biobutanol, validated reference genes have not yet been reported. In this study, we selected 160 genes with stable expression based on an RNA sequencing (RNA-Seq) data analysis, and among them, seven genes (, , , , , , and ) were selected for experimental validation by RT-qPCR and gene ontology (GO) enrichment analysis. According to statistical analyses, and were the most stable and suitable reference genes for RT-qPCR normalization. Furthermore, our methodology can be useful for selection of the reference genes in other strains of and it also suggests that the RNA-Seq data can be used for the initial selection of novel reference genes, however, their validation is required.

Chapter 5: THE ROLE OF GENETICS IN PRIMARY HYPERPARATHYROIDISM.

Around 10% of cases of primary hyperparathyroidism are thought to be genetic in origin, some of which are part of a syndromic form such as multiple endocrine neoplasia types 1, 2A or 4 or hyperparathyroidism-jaw tumor syndrome, while the remainder are cases of isolated familial primary hyperparathyroidism. Recognition of these genetic forms is important to ensure appropriate management according to the gene and type of variant involved, but screening for a genetic cause is not justified in all patients presenting primary hyperparathyroidism. The indications for genetic analysis have made it possible to propose a decision tree that takes into account whether the presentation is familial or sporadic, syndromic or isolated, patient age, and histopathological type of parathyroid lesion.

Introduction: Nakaseomyces glabratus is considered a high priority of attention according to WHO, and also is an important yeast species due to its high rate of intrinsic/acquired resistance against fluconazole. This study aimed at the possible mechanisms of action of thymol, as the promising new antifungal agent, in N. glabratus.

Extracellular vesicles (EVs) play a key role in cancer development and cellular homeostasis by transferring the biological cargo to recipient cells. Here, we describe steps for screening EV secretion-related genes by combining a microRNA (miRNA) library and ExoScreen, a highly sensitive EV detection technique. We also detail procedures for screening the direct target genes regulated by miRNAs.

Background: Epidemiological surveys indicate an increasing incidence of type 2 diabetes mellitus (T2DM) among children and adolescents worldwide. Due to rapid disease progression, severe long-term cardiorenal complications, a lack of effective treatment strategies, and substantial socioeconomic burdens, it has become an urgent public health issue that requires management and resolution. Adolescent T2DM differs from adult T2DM.

Recent advances in molecular science have significantly enlightened our mechanistic understanding of spinocerebellar ataxia type 7. To further close remaining gaps, we performed a multi-omics analysis using SCA7 mice. Entire brain tissue samples were collected from 12-week-old mice, and RNA sequencing, methylation analysis, and proteomic analysis were performed.
