KLF2 protects BV2 microglial cells against oxygen and glucose deprivation injury by modulating BDNF/TrkB pathway.
Abstract Cerebral ischemia injury is common in cerebral ischemic disease, and treatment options remain limited. Krueppel-like factor 2 (KLF2) is reported to negatively regulate inflammation in several ischemic diseases. Our study aimed to investigate the effects and underlying mechanism of KLF2 in BV2 microglial cells exposed to oxygen and glucose deprivation (OGD). We first found decreased KLF2 and toll-like receptor 2 (TLR2)/TLR4 in these cells. OGD also led to decrease in cell viability and increase in LDH release, apoptosis, the Bax/Bcl-2 ratio, and caspase3/9 expression, as well as production of inflammatory ...

Genome-wide analysis of mammary gland shows modulation of transcriptome landscape with alternative splice variants in Staphylococcus aureus mastitis in mice.
Abstract Epidemiological mapping shows Staphylococcus aureus to be the leading mastitis causing pathogen in India with diverse genetic lineages circulating in the dairy cattle population. We previously reported that endemic clonal strains of S. aureus isolated from subclinical mastitis lead to specific alteration of epigenetic modulators resulting in deviating immune response in intramammary infection mouse model. However, the extent of transcriptome modulation and associated alternative splicing in S. aureus mastitis is poorly understood. Hence, to gain a deeper insight of the extent of modulation of transcriptom...

Abstract To explore its roles in adipogenesis, the levels of genomic 5mC methylation were examined across the adipocyte differentiation of 3T3-L1 cells. This led to the identification of an up-regulating 5mC profile during the process. To further explore the regulation, gene expression assay was performed with a set of 5mC metabolic enzymes. Among them, TET2 was found to be the most regulated 5mC demethylase, in addition to a well-investigated 5mC methylase DNMT1. In the process, the expression of Tet2 increased for over 16-fold, suggesting its implications in the differentiation. Therefore, loss-of-function and g...

Celiac disease associated snp rs17810546 is located in a gene silencing region.
Abstract GWAS studies have identified variant rs17810546 in a non-coding region on chromosome 3 as a risk factor for several auto-immune diseases, including Celiac Disease. In silico analysis reveals that this variant is located in a transcription regulatory site. By means of reporter constructs we show that this region can override the expression rate of a gene as determined by its native promoter and that this modulation is influenced by the genetic composition of the haplotype which rs17810546 forms with a nearby other variant, rs761008. Secondly, we present data that this genetically imprinted modulation could...

Novel Splice Site and Nonsense Variants in INVS Cause Infantile Nephronophthisis.
We report a child with bilateral enlarged, echogenic, polycystic kidneys with end-stage renal disease, anemia and metabolic acidosis caused by biallelic novel pathogenic variants, c.796+5G>A and c.1789C>T in INVS. We show that the variant, c.796+5G>A disrupts the canonical splicing and nonsense variant, c.1789C>T results in nonsense mediated decay.

Molecular evolution of autophagy rate-limiting factor LAMP2 in placental mammals.
Abstract Autophagy is the cellular process of removal of misfolded or damaged macromolecules and organelles. Experimental studies have demonstrated autophagy as a major mechanism of lifespan extension in long-lived mammals such as bats and mole rat rodents. Moreover, the role of this biological process has been well documented in protection against age-associated diseases and viral infection. However, studies on the molecular adaptive changes of autophagy factors during evolution are scarce. Here, we conducted a bioinformatics study of the molecular evolution of the Lysosomal Associated Membrane Protein 2 (LAMP2),...

Epigenetic inheritance and intergenerational effects in mollusks.
Abstract Recent insights in evolutionary biology have shed light on epigenetic variation that interacts with genetic variation to convey heritable information. An important characteristic of epigenetic changes is that they can be produced in response to environmental cues and passed on to later generations, potentially facilitating later genetic adaptation. While our understanding of epigenetic mechanisms in vertebrates is rapidly growing, our knowledge about invertebrates remains lower, or is restricted to model organisms. Mollusks in particular, are a large group of invertebrates, with several species important ...

The in silico characterization of neutral alpha-glucosidase C (GANC) and its evolution from GANAB.
;ko M Abstract In the Carbohydrate-Active enZymes database (CAZy) glycoside hydrolases (GHs) are classified presently into 156 GH families. In human, there are five known enzymes from the family GH31. Two (MGAM and SI) are intestinal glucosidases involved in saccharide digestion, the acidic glucosidase (GAA) is responsible for glycogen degradation in lysosomes and GANAB (glucosidase II) plays a role in the control of a proper protein folding in the endoplasmic reticulum. The fifth protein is called GANC. It is an α-glucosidase, which is able to release the terminal glucose from maltotriose and glycogen at ne...

Whole Exome Sequencing identified two homozygous ALMS1 Mutations in an Iranian Family with Alstr öm Syndrome.
This study aimed to identify pathogenic mutations in a consanguineous Iranian family with AS. Next-generation sequencing was performed on the genomic DNA obtained from a 12 years old girl with AS. According to the bioinformatics analysis, computational modelling and segregation of variants, we identified two homozygous mutations close together in exon 8 of ALMS1 in the patient, including c.7262 G>T and c.7303-7305delAG. The clinically normal parents were heterozygous for both mutations. These mutations have a very rare frequency and only reported in the heterozygous state in the public genomic databases. Overall, due to...

Associated of rs895819 with risk of stomach neoplasms.
Abstract A recent study published in GENE performed a meta-analysis on the relationship between genetic variant rs895819 in microRNA-27a and risk of stomach neoplasms, and the results indicated an association of rs895819 with increased risk of stomach neoplasms in heterogenous model among Chinese. However, the meta-analysis did not include one large sample size of study that met inclusion criteria. When including all related studies, our meta-analysis showed no significant association of rs895819 with stomach neoplasms risk in each different model in all population, Chinese and Europeans. Thus, pooling all related...

A novel splice site variant in ANOS1 gene leads to Kallmann syndrome in three siblings.
Abstract Idiopathic hypogonadotropic hypogonadism (IHH) is a rare genetic disease caused by low doses of hypothalamic gonadotropin-releasing hormone (GnRH), leading to absence or delayed sexual development. Kallmann syndrome (KS) is characterized by IHH with anosmia or hyposmia. Here, we identified a novel splice site variant (c. 726+2T>G) of ANOS1 gene in three siblings with KS from a Chinese Han family by whole-exome sequencing (WES). In this family, KS is classified as an X-linked recessive inheritance pattern. This mutation was inherited from the mother by Sanger sequencing. An in vitro functional experimen...
