REVIEW
Abdul Waheed, William S Sly
Human CAXII was initially identified as a cancer marker in different cancers and tumors. Expression of CAXII is regulated by hypoxia and estrogen receptors. CAXII expression has been also detected in several tissues, whereas in cancer and tumor tissues its expression is several fold higher. In brain tumors, an alternatively spliced form of CAXII is expressed. Higher expression of CAXII in breast cancer is indicative of lower grade disease. CAXII plays a key role in several physiological functions. Mutation in the CAXII gene causes cystic fibrosis-like syndrome and salt wasting disease...

The economic and biological significance of blunt snout bream (Megalobrama amblycephala) makes this species important to explore the underlying molecular mechanism of hypoxia response. In the present study, we compared the transcriptional responses to serious hypoxia in skeletal muscle among hypoxia tolerant (MT), sensitive (MS) and control (without hypoxia treatment, MC) M. amblycephala obtained according to the time difference of losing balance after hypoxia treatment. A total of 88,200,889 clean reads were generated and assembled into 44,493 unigenes...

Increasing evidences show that ubiquitous perfluorooctanoic acid (PFOA), a representative environmental pollutant, is found to be linked to lipid dysmetabolism. However, the biological mechanism behind this outcome remains uninvestigated. In the present study, we established the PFOA-injured liver in mice to explore the underlying mechanism associated with PFOA-induced lipid disturbance in the liver via a group of biochemical and molecular assays. As results, PFOA-exposed mice showed increased transaminase (ALT), reduced triglyceride and free fatty acid contents in serum, as well as elevated level of hepatic triglyceride...

BACKGROUND: Emerging evidence suggests that curcumin can overcome drug resistance to classical chemotherapies, but poor bioavailability and low absorption have limited its clinical use and the mechanisms remain unclear. Also, Adriamycin (Adr) is one of the most active cytotoxic agents in breast cancer; however, the high resistant rate of Adr leads to a poor prognosis. METHODS: We utilized encapsulation in liposomes as a strategy to improve the bioavailability of curcumin and demonstrated that liposomal curcumin altered chemosensitivity of Adr-resistant MCF-7 human breast cancer (MCF-7/Adr) by MTT assay...

Arginase (ARG) catalyzes the final step of ornithine-urea cycle (OUC) leading to a conversion of L-arginine to L-ornithine and urea. Several isoforms of ARG have been reported in vertebrates, out of which the two predominant isoforms are the cytosolic ARG1 and the mitochondrial ARG2. The air-breathing walking catfish (Clarias batrachus) is frequently being challenged by different environmental insults such as hyper-ammonia, dehydration and osmotic stresses in their natural habitats throughout the year. The present study investigated the active presence of ARG1 and ARG2 isoforms in hepatocytes along with unique localization of both the isoforms inside the mitochondria, and also their specific expression patterns under hyper-ammonia stress (5mM NH4Cl) in isolated hepatocytes of walking catfish...

BACKGROUND: Triple-Negative breast cancer (TNBC), accounts for a large percentage of breast cancer cases in India including Northeast India. TNBC has an unclear molecular aetiology and hence limited targeted therapies. Human breast is comprised of glandular, ductal, connective, and adipose tissues. Adipose tissue is composed of adipocytes. The adipocytes apart from being energy storage depots, are also active sources of adipocytokines and/or adipokines. The role of adipokines in breast cancer including TNBC has been sporadically documented...

The Indian meal moth Plodia interpunctella (Lepidoptera: Pyralidae) is a worldwide pest that causes serious damage to stored foods. Although many efforts have been conducted on this species due to its economic importance, the study of genetic basis of development, behavior and insecticide resistance has been greatly hampered due to lack of genomic information. In this study, we used high throughput sequencing platform to perform a de novo transcriptome assembly and tag-based digital gene expression profiling (DGE) analyses across four different developmental stages of P...

Friedreich's ataxia (FRDA) is a neurodegenerative disease caused by reduced expression of the protein frataxin. Frataxin is thought to play a role in iron-sulfur cluster biogenesis and heme synthesis. In this study, we used erythroid progenitor stem cells obtained from FRDA patients and healthy donors to investigate the putative role, if any, of frataxin deficiency in heme synthesis. We used electrochemiluminescence and qRT-PCR for frataxin protein and mRNA quantification. We used atomic absorption spectrophotometry for iron levels and a photometric assay for hemoglobin levels...

Increasing evidence has suggested that B7-H4 plays an important role in cancer development not only in immune field. However, the correlation between B7-H4 protein expression and clinical outcome in primary breast cancer has not been investigated. We examined the expression of B7-H4 by Immunohistochemistry in 147 cases of invasive breast carcinomas. Correlation of B7-H4 protein levels with pathological tumor stages and overall survival rates of breast cancer patients were also analyzed. Uni-and multivariate analyses methods were performed to evaluate the prognostic value of B7-H4 expression levels...

Bax, a pro-apoptotic member of Bcl-2 family regulates apoptosis through homodimerization/heterodimerization with Bcl-2. Bax-α is the only product of the Bax gene that has been extensively studied. Bax-α exists in inactive form and several conformational changes are required during apoptosis to activate it. Here, we have identified a novel transcript variant of Bax gene in mouse which contains alternatively spliced new first exon that is different from the first exon of previously reported transcript. Conceptual translation of new transcript encodes a protein (Bax-α1), having different N-terminus...

MicroRNAs (miRNAs) are universal regulators that repress target gene expression in eukaryotes and play essential roles in plant immune responses. miRNAs were recently found to be involved in soybean and Phytophthora sojae interactions. Here, we screened miR1510, which was repressed in soybean during infection with P. sojae, indicating that it might be involved in soybean response to pathogens. To further uncover the roles of miRNAs in soybean, gma-miR1510a/b was overexpressed in the hairy roots of soybean using an Arabidopsis miR319a precursor as the backbone...

Kallmann syndrome (KS) is characterized by isolated hypogonadotropic hypogonadism (IHH) with anosmia. Fibroblast growth factor receptor 1 (FGFR1) is one of KS-associated genes, account for approximately 10% of total patients. FGFR1 mutations have also been identified in more severe craniosynostosis syndromes, and a subset of craniosynostosis syndromes-associated FGFR1 mutations show dominant negative effect. In this study, we identified a novel FGFR1 mutation (c.867G>A; p.W289X) in a KS patient. The p.W289X mutation leads premature termination, producing a truncated FGFR1 without the transmembrane and intracellular domains...

Low-density lipoprotein receptor-related protein (LRP) is a group of important endocytic receptors contributing to binding ligands and maintaining internal environment. In this study, we identified a soluble LRP-like molecule in the amphioxus B. japonicum, BjLRP, with an uncharacterized domain structure combination of LY-EGF-CRD-EGF-CRD. It was mainly expressed in the gill, muscle, notochord and testis, and was significantly up-regulated following the challenge with bacteria. Recombinant BjLRP was capable of interacting with both Gram-negative and positive bacteria as well as PAMPs including lipopolysaccharide (LPS), lipoteichoic acid (LTA) and peptidoglycan (PGN)...

MicroRNAs (miRNAs) are a class of non-coding RNAs that play a crucial regulatory role in many biological processes. Previous studies have reported miRNAs that are associated with the growth, differentiation, and proliferation of myocytes and adipocytes in pigs. However, differences in the miRNA expression profiles between muscle and adipose tissues during porcine development are unknown. Muscle and adipose tissues are the two major organs that are crucial for dynamic energy balance in the development and metabolism...

NF-κB may promote tumor progression by altering cell metabolism. Hence, finding its target genes that are involved in cell metabolism is helpful for understanding its role in tumor growth. Here we discovered four metabolism-related target genes of this transcription factor. By analyzing a chromatin immunoprecipitation followed by deep sequencing (ChIP-Seq) data that characterizing the global binding sites (BSs) of NF-κB RelA in the TNFα-stimulated HeLa cells, we found that four genes that encode core enzymes of the tricarboxylic acid (TCA) cycle, including IDH1, IDH3A, ACO2, and SUCLA2, were multiply bound by this transcription factor...

Traditional subspecies call attention to differences between geographic populations with research potential, but their value is often in need of revision. Genetic data can be useful for evaluating the taxonomic validity of historical species and subspecies designations or for identifying morphologically cryptic divergent lineages worthy of further in-depth taxonomic study. The desert hedgehog (Paraechinus aethiopicus) has a wide but fragmented distribution in arid and semi-arid habitats from the northwest to the northeast of Africa and southwestern Asia, and its taxonomy is still unclear...

Lung cancer is one of the deadliest types of cancers and genetic and epigenetic alterations play major roles in its development. Chromodomain (CHD) protein family acts in chromatin organization, regulation of transcription and also genomic stability and cancer prevention. Although CHD5, a member of this family was shown to contribute to major cellular events and functions as a tumor suppressor gene in various types of cancer, it is not clear whether CHD5 plays a role in lung carcinogenesis. The aim of this study was to investigate the possible role of CHD5 in progression of non-small cell lung cancer (NSCLC)...
