Global RNA profiles show target selectivity and physiological effects of peptide-delivered antisense antibiotics.

Nucleic Acids Res 2021 Apr 13. Epub 2021 Apr 13.

Institute of Molecular Infection Biology (IMIB), University of Würzburg, D-97080 Würzburg, Germany.

Antisense peptide nucleic acids (PNAs) inhibiting mRNAs of essential genes provide a straight-forward way to repurpose our knowledge of bacterial regulatory RNAs for development of programmable species-specific antibiotics. While there is ample proof of PNA efficacy, their target selectivity and impact on bacterial physiology are poorly understood. Moreover, while antibacterial PNAs are typically designed to block mRNA translation, effects on target mRNA levels are not well-investigated. Read More

Augmentation of the heat shock axis during exceptional longevity in Ames dwarf mice.

Geroscience 2021 Apr 13. Epub 2021 Apr 13.

Department of Geriatrics, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, ND, 58202, USA.

How the heat shock axis, repair pathways, and proteostasis impact the rate of aging is not fully understood. Recent reports indicate that normal aging leads to a 50% change in several regulatory elements of the heat shock axis. Most notably is the age-dependent enhancement of inhibitory signals associated with accumulated heat shock proteins and hyper-acetylation associated with marked attenuation of heat shock factor 1 (HSF1)-DNA binding activity.

Oncol Rep 2021 Jun 13;45(6). Epub 2021 Apr 13.

Research Centre, The Fourth Hospital of Hebei Medical University, Shijiazhuang, Hebei 050011, P.R. China.

As esophageal squamous cell carcinoma (ESCC) is one of the most frequently diagnosed cancers in Asia, it is crucial to uncover its underlying molecular mechanisms that support its development and progression. Several articles have reported that microRNA (miR)‑485‑5p inhibits the malignant phenotype in a number of cancer types, such as lung, gastric and breast cancer, but to the best of our knowledge, its function in ESCC has not been studied in depth until the present study. It is of great significance to probe the regulatory action and underlying mechanism of miR‑485‑5p in ESCC. Read More

Changes in the phosphorylation of nucleotide metabolism‑associated proteins by leukemia inhibitory factor in mouse embryonic stem cells.

Mol Med Rep 2021 Jun 13;23(6). Epub 2021 Apr 13.

Department of Microbiology, Jeonbuk National University Medical School, Jeonju, Jeollabuk 54896, Republic of Korea.

Leukemia inhibitory factor (LIF) is a stem cell growth factor that maintains self‑renewal of mouse embryonic stem cells (mESCs). LIF is a cytokine in the interleukin‑6 family and signals via the common receptor subunit gp130 and ligand‑specific LIF receptor. LIF causes heterodimerization of the LIF receptor and gp130, activating the Janus kinase/STAT and MAPK pathways, resulting in changes in protein phosphorylation. Read More

Nat Neurosci 2021 Apr 12. Epub 2021 Apr 12.

Department of Psychiatry, Emory University School of Medicine, Atlanta, GA, USA.

Depression is a common condition, but current treatments are only effective in a subset of individuals. To identify new treatment targets, we integrated depression genome-wide association study (GWAS) results (N = 500,199) with human brain proteomes (N = 376) to perform a proteome-wide association study of depression followed by Mendelian randomization. We identified 19 genes that were consistent with being causal in depression, acting via their respective cis-regulated brain protein abundance. Read More

Sustained high expression of multiple APOBEC3 cytidine deaminases in systemic lupus erythematosus.

Sci Rep 2021 Apr 12;11(1):7893. Epub 2021 Apr 12.

Molecular Retrovirology Unit, UMR 3569, Institut Pasteur, CNRS, 28 rue du Dr. Roux, 75724, Paris cedex 15, France.

APOBEC3 (A3) enzymes are best known for their role as antiviral restriction factors and as mutagens in cancer. Although four of them, A3A, A3B, A3F and A3G, are induced by type-1-interferon (IFN-I), their role in inflammatory conditions is unknown. We thus investigated the expression of A3, and particularly A3A and A3B because of their ability to edit cellular DNA, in Systemic Lupus Erythematosus (SLE), a chronic inflammatory disease characterized by high IFN-α serum levels.

Role of Hakai in mA modification pathway in Drosophila.

Nat Commun 2021 04 12;12(1):2159. Epub 2021 Apr 12.

State Key Laboratory of Genetic Engineering, School of Life Sciences, Fudan University, Shanghai, China.

N6-methyladenosine (mA), the most abundant internal modification in eukaryotic mRNA, is installed by a multi-component writer complex; however, the exact roles of each component remain poorly understood. Here we show that a potential E3 ubiquitin ligase Hakai colocalizes and interacts with other mA writer components, and Hakai mutants exhibit typical mA pathway defects in Drosophila, such as lowered mA levels in mRNA, aberrant Sxl alternative splicing, wing and behavior defects. Hakai, Vir, Fl(2)d and Flacc form a stable complex, and disruption of either Hakai, Vir or Fl(2)d led to the degradation of the other three components. Read More
