The role of PD-1/PD-L1 checkpoint in arsenic lung tumorigenesis.

Toxicol Appl Pharmacol 2021 Jun 21:115633. Epub 2021 Jun 21.

Department Pharmacology & Nutritional Sciences, University of Kentucky College of Medicine, Lexington, KY 40536, USA. Electronic address:

Chronic exposure to environmental arsenic promotes lung cancer. Emerging evidence indicates that compromised host immunity, particularly T cell anti-tumor immunity, may play a critical role in cancer development. However, there is a knowledge gap in terms of the effects of arsenic exposure on T cell anti-tumor immunity and how that may contribute to arsenic lung carcinogenicity. Read More

Using Multilayer Heterogeneous Networks to Infer Functions of Phosphorylated Sites.

J Proteome Res 2021 Jun 24. Epub 2021 Jun 24.

Division of Molecular and Cellular Function, School of Biological Sciences, Faculty of Biology, Medicine & Health, University of Manchester, Manchester M13 9PT, U.K.

Mass spectrometry-based quantitative phosphoproteomics has become an essential approach in the study of cellular processes such as signaling. Commonly used methods to analyze phosphoproteomics datasets depend on generic, gene-centric annotations such as Gene Ontology terms, which do not account for the function of a protein in a particular phosphorylation state. Analysis of phosphoproteomics data is hampered by a lack of phosphorylated site-specific annotations. Read More

Prognostic Value of Immune-Related lncRNA SBF2-AS1 in Diffuse Lower-Grade Glioma.

Technol Cancer Res Treat 2021 Jan-Dec;20:15330338211011966

Department of Hepatopancreatobiliary Surgery, The People's Hospital of Lishui, Lishui, Zhejiang, China.

LncRNA SET-binding factor 2 (SBF2) antisense RNA1 (SBF2-AS1) has been proven to play an oncogenic role in various types of tumors, but the prognostic role of SBF2-AS1 in tumors, especially in diffuse lower-grade glioma (LGG), is still unclear. Here, we aimed to investigate the prognostic value of SBF2-AS1 in LGG. The LGG expression profiles from The Cancer Genome Atlas (TCGA, = 524) and Chinese Glioma Genome Atlas (CGGA, = 431) were mined by Kaplan-Meier analysis, Cox regression analysis, Chi-square test and GSEA analysis.

Surface-Shaving Proteomics of Mycobacterium marinum Identifies Biofilm Subtype-Specific Changes Affecting Virulence, Tolerance, and Persistence.

mSystems 2021 Jun 22:e0050021. Epub 2021 Jun 22.

Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland.

The complex cell wall and biofilm matrix (ECM) act as key barriers to antibiotics in mycobacteria. Here, the ECM and envelope proteins of Mycobacterium marinum ATCC 927, a nontuberculous mycobacterial model, were monitored over 3 months by label-free proteomics and compared with cell surface proteins on planktonic cells to uncover pathways leading to virulence, tolerance, and persistence. We show that ATCC 927 forms pellicle-type and submerged-type biofilms (PBFs and SBFs, respectively) after 2 weeks and 2 days of growth, respectively, and that the increased CelA1 synthesis in this strain prevents biofilm formation and leads to reduced rifampicin tolerance.

Strategies to improve viability of a circular carbon bioeconomy-A techno-economic review of microbial electrosynthesis and gas fermentation.

Water Res 2021 May 27;201:117306. Epub 2021 May 27.

Advanced Water Management Centre, The University of Queensland, Brisbane, QLD 4072, Australia. Electronic address:

A circular carbon bioeconomy has potential to halt atmospheric accumulation of greenhouse gases causing climate change and sustainably produce chemical, agricultural and fuel products. Here, we report application of a simplified technoeconomic assessment to critically review two approaches in this space - microbial electrosynthesis and gas fermentation. For microbial electrosynthesis, decoupling of surface-dependant abiotic process for electron delivery from volume-dependant biotic carbon fixation, is shown as the only economically viable strategy to scale-up due to comparatively low biofilm electron consumption rate.

Mn(II) Complex of Lipophilic Group-Modified Ethylenediaminetetraacetic Acid (EDTA) as a New Hepatobiliary MRI Contrast Agent.

J Med Chem 2021 Jun 21. Epub 2021 Jun 21.

Department of Radiotherapy, Sichuan Cancer Hospital & Institute, Chengdu 610041, China.

Liver-specific contrast agents (CAs) can improve the Magnetic resonance imaging (MRI) detection of focal and diffuse liver lesions by increasing the lesion-to-liver contrast. A novel Mn(II) complex, Mn-BnO-TyrEDTA, with a lipophilic group-modified ethylenediaminetetraacetic acid (EDTA) structure as a ligand to regulate its behavior in vivo, is superior to Gd-EOB-DTPA in terms of a liver-specific MRI contrast agent. An MRI study on mice demonstrated that Mn-BnO-TyrEDTA can be rapidly taken up by hepatocytes with a combination of hepatobiliary and renal clearance pathways. Read More

An Integrated Analysis of the Response of Colorectal Adenocarcinoma Caco-2 Cells to X-Ray Exposure.

Front Oncol 2021 3;11:688919. Epub 2021 Jun 3.

Laboratory of Radiation Biophysics and Radiobiology, Department of Physics, University of Pavia, Pavia, Italy.

Colorectal cancer is among the three top cancer types for incidence and the second in terms of mortality, usually managed with surgery, chemotherapy and radiotherapy. In particular, radiotherapeutic concepts are crucial for the management of advanced rectal cancer, but patients' survival remains poor, despite advances in treatment modalities. The use of well-characterized cell culture systems offers an important preclinical strategy to study mechanisms at the basis of cell response to therapeutic agents, including ionizing radiation, possibly leading to a better understanding of the response to the treatment.

Analysis of the transcriptome of bovine endometrial cells isolated by laser micro-dissection (1): specific signatures of stromal, glandular and luminal epithelial cells.

BMC Genomics 2021 Jun 18;22(1):451. Epub 2021 Jun 18.

Université Paris-Saclay, UVSQ, INRAE, BREED, 78350, Jouy-en-Josas, France.

Background: A number of studies have examined mRNA expression profiles of bovine endometrium at estrus and around the peri-implantation period of pregnancy. However, to date, these studies have been performed on the whole endometrium which is a complex tissue. Consequently, the knowledge of cell-specific gene expression, when analysis performed with whole endometrium, is still weak and obviously limits the relevance of the results of gene expression studies.

Improved Sampling and Free Energy Estimates for Antibiotic Permeation through Bacterial Porins.

J Chem Theory Comput 2021 Jun 17. Epub 2021 Jun 17.

Department of Physics and Earth Sciences, Jacobs University Bremen, 28759 Bremen, Germany.

Antibiotics enter into bacterial cells via protein channels that serve as low-energy pathways through the outer membrane, which is otherwise impenetrable. Insights into the molecular mechanisms underlying the transport processes are vital for the development of effective antibacterials. A much-desired prerequisite is an accurate and reproducible determination of free energy surfaces for antibiotic translocation, enabling quantitative and meaningful comparisons of permeation mechanisms for different classes of antibiotics.
