The dual function gene RAD23 contributes to Cryptococcus neoformans virulence independently of its role in nucleotide excision DNA repair.
Abstract Genes involved in the repair of DNA damage are emerging as playing important roles during the disease processes caused by pathogenic fungi. However, there are potentially hundreds of genes involved in DNA repair in a fungus and some of those genes can play additional roles within the cell. One such gene is RAD23, required for virulence of the human pathogenic fungus Cryptococcus neoformans, that encodes a protein involved in the nucleotide excision repair (NER) pathway. However, Rad23 is a dual function protein, with a role in either repair of damaged DNA or protein turn over by directing proteins to the ...

Genetic mutation analysis of the COQ2 gene in Italian patients with multiple system atrophy.
Abstract COQ2 encodes para-hydroxybenzoate-polyprenyl transferase and, recently, mutations in this gene have been associated with the increase of the risk of multiple system atrophy (MSA) in Japanese cases. Subsequently, studies in Asian patients confirmed the role of COQ2 in the development of MSA, while other analysis failed to replicate these results in Caucasian population. We performed genetics screening of COQ2 in 100 MSA Italian patients. We did not find any pathogenic mutations; our results suggest that COQ2 is not a genetic risk factor for MSA in Italian population. PMID: 31398377 [PubMed - as suppli...

Circ-IGF1R has pro-proliferative and anti-apoptotic effects in HCC by activating the PI3K/AKT pathway.
In this study, we identified a novel circRNA, circ-IGF1R, in HCC tumour tissues and cell lines. Circ-IGF1R levels were found to be significantly upregulated in HCC tissues compared with levels in paired peritumoural tissues. The high expression levels of circ-IGF1R in HCC were associated with tumour size. Moreover, knocking down circ-IGF1R with siRNA significantly attenuated cell proliferation and induced cell apoptosis and cell cycle arrest in vitro. Further investigation revealed that PI3K/AKT signalling pathway activation was involved in the oncogenic functions of circ-IGF1R in HCC. Our study suggests that circ-IGF1R ma...

A novel mutation of the ITGB2 gene in a Chinese Zhuang minority patient with leukocyte adhesion deficiency type 1 and glucose-6-phosphate dehydrogenase deficiency.
CONCLUSIONS: The patient was diagnosed with G6PDD and moderate LAD-1. The combination of LAD-1 and G6PDD in this case may have been due to the high incidence of genetic disease in this minority ethnic population. Analyzing existing LAD-1 and G6PDD cases from different populations can facilitate disease diagnosis and treatment. Particularly, reporting pathogenic mutations of LAD-1 and G6PDD will be crucial for genetic testing and prenatal diagnosis in an effort to decrease the incidence of these diseases.

Functional diversification of tomato HsfA1 factors is based on DNA binding domain properties.
Abstract In all eukaryotes, the response to heat stress (HS) is dependent on the activity of HS transcription factors (Hsfs). Plants contain a large number of Hsfs, however, only members of the HsfA1 subfamily are considered as master regulators of stress response and thermotolerance. In Solanum lycopersicum, among the four HsfA1 members, only HsfA1a has been proposed to possess a master regulator function. We performed a comparative analysis of HsfA1a, HsfA1b, HsfA1c and HsfA1e at different levels of regulation and function. HsfA1a is constitutively expressed under control and stress conditions, while the other m...

CONCLUSIONS: Our meta-analysis found the qualitative detection (methylation); TNM stage I-IV, publication year 2011-2018 were related to more effective diagnostic accuracy for OC. However, serum-based cell-free DNA detection should be cautiously interpreted due to unclear factors. Hence, further large-scale longitudinal studies are required to validate the diagnostic potential of cell-free DNA. The present study provides to accrue knowledge of cell-free DNA levels for future researches. PMID: 31330238 [PubMed - as supplied by publisher] (Source: Gene)

Further studies of ion channels in the electroreceptor of the skate through deep sequencing, cloning and cross species comparisons.
Abstract Our comparative studies seek to understand the structure and function of ion channels in cartilaginous fish that can detect very low voltage gradients in seawater. The principal channels of the electroreceptor include a calcium activated K channel whose α subunit is Kcnma1, and a voltage-dependent calcium channel, Cacna1d. It has also been suggested based on physiological and pharmacological evidence that a voltage-gated K channel is present in the basal membranes of the receptor cells which modulates synaptic transmitter release. Large conductance calcium-activated K channels (BK) are comprised of ...

The study of genes and signal transduction pathways involved in mustard lung injury: A gene therapy approach.
Abstract Sulfur mustard (SM) is a destructive and harmful chemical agent for the eyes, skin and lungs that causes short-term and long-term lesions and was widely used in Iraq war against Iran (1980-1988). SM causes DNA damages, oxidative stress, and Inflammation. Considering the similarities between SM and COPD (Chronic Obstructive Pulmonary Disease) pathogens and limited available treatments, a novel therapeutic approach is not developed. Gene therapy is a novel therapeutic approach that uses genetic engineering science in treatment of most diseases including chronic obstructive pulmonary disease. In this review,...

Analysis of genetic diversity and population structure using SSR markers and validation of a Cleavage Amplified Polymorphic Sequences (CAPS) marker involving the sodium transporter OsHKT1;5 in saline tolerant rice (Oryza sativa L.) landraces.
Abstract Naturally evolved saline tolerant rice landraces found along the coastline of India are a valuable genomic resource to explore the complex, polygenic nature of salinity tolerance. In the present study, a set of 28 genome wide SSR markers, 11 salt responsive genic SSR markers and 8 Saltol QTL linked SSR markers were used to estimate genetic relatedness and population structure within a collection of 47 rice landraces (including a tolerant and 2 sensitive checks) originating from geographically divergent coastal regions of India. All three marker types identified substantial genetic variation among the land...

Evolution of S100A3 and PAD3, two important genes for mammalian hair.
Abstract Hair is one of the defining characteristics of mammals. The hair shaft has a two-layer structure comprising the cortex, which is the inner layer and is composed of cortical cells, and the cuticle, which is the outermost layer. S100 calcium-binding protein A3 (S100A3) is expressed at high levels in the human hair cuticle. Arginine 51 of S100A3 protein is citrullinated specifically by peptidyl arginine deiminase 3 (PAD3), and this citrullination is related to maturation of the cuticle. However, the detailed evolutionary processes of S100A3 and PAD3 during mammalian evolution are unknown. Here, we show that ...

Compound heterozygous mutations in SMO associated with anterior segment dysgenesis and morning glory syndrome.
Abstract Eye development in vertebrates is a highly coordinated multistep process while defects in key factors might lead to severe congenital ocular disorders. SMO encodes a G protein-coupled receptor that functions in Hedgehog signal transduction, an essential step during eye development. Here we reported the first identification of compound heterozygous mutations (c.G338A; p.R113Q and c.C1619T; p.A540V) in the SMO gene in a patient with both anterior segment dysgenesis (congenital corneal opacity, cataract) and morning glory syndrome, using trio-based whole exome sequencing. The clinical manifestations of this ...

Overcoming multiple drug resistance in lung cancer using siRNA targeted therapy.
Abstract Among cancers, lung cancer is the most morbidity and mortality disease that is remaining the fatalist. Generally, there are multiple treatment procedures for lung cancer, such as surgery, immunotherapy, radiotherapy and chemotherapy. There is, therefore, an urgent need for more specified and efficient methods for treatment of lung cancer such as RNAi, which in combination with traditional therapies could silence genes that are involved in the drug resistance. These genes may either be motivators of apoptosis inhibition, EMT and DNA repair system promoters or a member of intracellular signaling pathways, s...

A SEPALLATA1-like gene of Isatis indigotica Fort. regulates flowering time and specifies floral organs.
Abstract An orthologous gene of SEPALLATA1, designated as IiSEP1, was isolated from Isatis indigotica. The genomic DNA of IiSEP1 is 3.1 Kb in length. The full-length cDNA of IiSEP1 is 1481 bp and contains a 756 bp ORF encoding a 251-amino-acid protein. Sequence comparison revealed that IiSEP1 belongs to the MADS-box gene family. IiSEP1 contains 7 exons and 6 introns, showing similar exon-intron structure with Arabidopsis SEP1. Phylogenetic analysis suggested that IiSEP1 belonged to AGL2/SEP subfamily and was likely to be an I. indigotica ortholog of Arabidopsis SEP1. Quantitative real-time PCR showed that IiSE...
