Long noncoding RNA GAS8-AS1: A novel biomarker in human diseases.

Biomed Pharmacother 2021 Apr 7;139:111572. Epub 2021 Apr 7.

Department of Neurosurgery, The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou 310003, China. Electronic address:

Long non-coding RNAs (lncRNAs) represent a group of ncRNAs with more than 200 nucleotides. These RNAs can specifically regulate gene expression at both the transcriptional and the post-transcriptional levels, and increasing evidence indicates that they play vital roles in a variety of disease-related cellular processes. The lncRNA GAS8 antisense RNA 1 (GAS8-AS1, also known as C16orf3) is located in the second intron of GAS8 and has been reported to be both abnormally expressed in several diseases and closely correlated with many clinical characteristics.

Two different patients with pulmonary pleomorphic carcinoma response to PD-1 inhibitor plus anlotinib.

Lung Cancer 2021 Mar 26;155:170-174. Epub 2021 Mar 26.

Department of Oncology, The Second Affiliated Hospital of Nanchang University, Nanchang, Jiangxi Province, China; Jiangxi Key Laboratory of Clinical Translational Cancer Research, Nanchang, Jiangxi Province, China. Electronic address:

Pulmonary pleomorphic carcinoma (PPC) is a rare and highly malignant subtype of non-small-cell lung cancer (NSCLC), and chemotherapy and radiotherapy are insensitive. Some clinical trials have shown that targetable driver gene mutations, such as EGFR, ALK or BRAF, have rarely been detected in PPC patients, but the incidence of MET exon 14 mutations is more frequent. For these patients with driver gene mutations, corresponding molecular targeted therapy may be valid. Read More

Nature Research Centre, Laboratory of Geoenvironmental Research, Akademijos St. 2, LT-08412 Vilnius, Lithuania; Vilnius University, Faculty of Chemistry and Geosciences, Naugarduko St. 24, LT-03225 Vilnius, Lithuania.

The present study tested the biological consequences of exposure to a multimetal mixture as a multiple chemical stressor on Oncorhynchus mykiss at molecular, cellular, physiological and whole-organism levels and on biomarker responses of this fish during the depuration period. To represent environmentally relevant multiple chemical stressors, in our study, we used the mixture of Zn, Cu, Ni, Cr, Pb and Cd at the concentrations corresponding to Maximum-Permissible-Concentrations (MPCs) acceptable for the EU inland waters. This study was undertaken with a view to elucidate if changes in the MPC of the test mixture components (Ni, Pb, Cd) could cause significantly different biomarker responses in O. Read More

Effects of dim artificial light at night on locomotor activity, cardiovascular physiology, and circadian clock genes in a diurnal songbird.

Environ Pollut 2021 Mar 31;282:117036. Epub 2021 Mar 31.

Department of Biology, University of Nevada, Reno, Reno, NV, USA.

Artificial light is transforming the nighttime environment and quickly becoming one of the most pervasive pollutants on earth. Across taxa, light entrains endogenous circadian clocks that function to synchronize behavioral and physiological rhythms with natural photoperiod. Artificial light at night (ALAN) disrupts these photoperiodic cues and has consequences for humans and wildlife including sleep disruption, physiological stress and increased risk of cardiovascular disease.

A novel tool to screen for treatments with clenbuterol in bovine: Identification of two hepatic markers by metabolomics investigation.

Food Chem 2021 Feb 23;353:129366. Epub 2021 Feb 23.

Istituto Zooprofilattico Sperimentale delle Venezie, Department of Chemistry, Legnaro (PD), Italy.

Surveillance of illegal use of growth promoters such as β-agonists in food producing animals rely on the detection of drug residues by LC-MS/MS. Screening strategies focusing on indirect physiological responses following administration of active compounds are promising approaches to strengthen existing targeted methods and ensure food safety. A metabolomics analysis based on LC-HRMS was carried out on liver extracts from bulls experimentally treated with clenbuterol combined with dexamethasone (n = 8) to mimic a potential anabolic practice, and control animals (n = 8).

Pharmacological inhibition of HSP90 radiosensitizes HNSCC xenograft by inhibition of DNA damage repair, nucleotide metabolism, and radiation-induced tumor vasculogenesis.

Int J Radiat Oncol Biol Phys 2021 Apr 7. Epub 2021 Apr 7.

Radiation Biology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD. Electronic address:

Purpose: Recent pre-clinical studies suggest combining the HSP90 inhibitor AT13387 (Onalespib) with radiation (IR) against colon cancer and HNSCC. These studies emphasized that AT13387 down-regulates HSP90 client proteins involved in oncogenic signaling and DNA repair mechanisms as major drivers of enhanced radiosensitivity. Given the large array of client proteins HSP90 directs, we hypothesized that other key proteins or signaling pathways may be inhibited by AT13387 and contribute to enhanced radiosensitivity.

Increased toxicity and retention of Perflourooctane Sulfonate (PFOS) in humanized CYP2B6-Transgenic mice compared to Cyp2b-null mice is relieved by a High-Fat Diet (HFD).

Food Chem Toxicol 2021 Apr 7:112175. Epub 2021 Apr 7.

Environmental Toxicology Program, Clemson University, Clemson, SC, 29634. Electronic address:

PFOS is a persistent, fluorosurfactant used in multiple products. Murine Cyp2b's are induced by PFOS and high-fat diets (HFD) and therefore we hypothesized that human CYP2B6 may alleviate PFOS-induced steatosis. Cyp2b-null and hCYP2B6-Tg mice were treated with 0, 1, or 10mg/kg/day PFOS by oral gavage for 21-days while provided a chow diet (ND) or HFD. Read More

Remodeling of Arctic char (Salvelinus alpinus) lipidome under a stimulated scenario of Arctic warming.

Glob Chang Biol 2021 Apr 10. Epub 2021 Apr 10.

Toxicology Centre, University of Saskatchewan, Saskatoon, SK, Canada.

Arctic warming associated with global climate change poses a significant threat to populations of wildlife in the Arctic. Since lipids play a vital role in adaptation of organisms to variations in temperature, high-resolution mass spectrometry based lipidomics can provide insights into adaptive responses of organisms to a warmer environment in the Arctic and help to illustrate potential novel roles of lipids in the process of thermal adaption. In this study, we studied an ecologically and economically important species-Arctic char (Salvelinus alpinus), with a detailed multi-tissue analysis of the lipidome in response to chronic shifts in temperature by use of a validated lipidomics workflow.

FABP5 enhances malignancies of lower-grade gliomas via canonical activation of NF-κB signaling.

J Cell Mol Med 2021 Apr 9. Epub 2021 Apr 9.

Department of Neurosurgery, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.

Low-grade gliomas (LGGs) are grade III gliomas based on the WHO classification with significant genetic heterogeneity and clinical properties. Traditional histological classification of gliomas has been challenged by the improvement of molecular stratification; however, the reproducibility and diagnostic accuracy of LGGs classification still remain poor. Herein, we identified fatty acid binding protein 5 (FABP5) as one of the most enriched genes in malignant LGGs and elevated FABP5 revealed severe outcomes in LGGs. Read More
