Mol Ther 2021 Jul 28. Epub 2021 Jul 28.

Cardiovascular Research Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA, 10029; Department of Genetics and Genomic Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA, 10029; Black Family Stem Cell Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA, 10029. Electronic address:

Reprogramming non-cardiomyocytes (non-CMs) into cardiomyocyte (CM)-like cells is a promising strategy for cardiac regeneration in conditions such as ischemic heart disease. Here, we used a modified mRNA (modRNA) gene delivery platform to deliver a cocktail of four cardiac-reprogramming genes (Gata4 (G), Mef2c (M), Tbx5 (T) and Hand2 (H)) together with three reprogramming-helper genes (Dominant Negative (DN)-TGFβ, DN-Wnt8a and Acid ceramidase (AC)), termed 7G-modRNA, to induce CM-like cells. We showed that 7G-modRNA reprogrammed 57% of CM-like cells in vitro. Read More

Defining the Role of Cellular Immune Signatures in Diagnostic Evaluation of Suspected Tuberculosis.

J Infect Dis 2021 Jul 31. Epub 2021 Jul 31.

TB Research Centre, National Heart and Lung Institute, Imperial College London, London, United Kingdom.

Background: Diagnosis of paucibacillary tuberculosis (TB) including extrapulmonary TB is a significant challenge, particularly in high-income, low-incidence settings. Measurement of Mycobacterium tuberculosis (Mtb)-specific cellular immune signatures by flow cytometry discriminates active TB from latent TB infection (LTBI) in case-control studies; however, their diagnostic accuracy and clinical utility in routine clinical practice is unknown.

Methods: Using a nested case-control study design within a prospective multicenter cohort of patients presenting with suspected TB in England, we assessed diagnostic accuracy of signatures in 134 patients who tested interferon-gamma release assay (IGRA)-positive and had final diagnoses of TB or non-TB diseases with coincident LTBI.

Front Mol Biosci 2021 13;8:689224. Epub 2021 Jul 13.

Department of Otorhinolaryngology, Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, Luzhou, China.

Long non-coding RNA (lncRNA) plays a significant role in the development, establishment, and progression of head and neck squamous cell carcinoma (HNSCC). This article aims to develop an immune-related lncRNA (irlncRNA) model, regardless of expression levels, for risk assessment and prognosis prediction in HNSCC patients. We obtained clinical data and corresponding full transcriptome expression of HNSCC patients from TCGA, downloaded GTF files to distinguish lncRNAs from Ensembl, discerned irlncRNAs based on co-expression analysis, distinguished differentially expressed irlncRNAs (DEirlncRNAs), and paired these DEirlncRNAs.

LPS-induced autophagy in human dental pulp cells is associated with p38.

J Mol Histol 2021 Jul 26. Epub 2021 Jul 26.

Department of Operative Dentistry and Endodontics, Hospital of Stomatology, Guanghua School of Stomatology, Sun Yat-sen University, 56 Ling yuan Road West, Guangzhou, 510055, China.

Lipopolysaccharides (LPS), which are components of the cell wall of Gram-negative bacteria, are among the important factors that induce inflammation, including pulpitis. Autophagy in human dental pulp cells (hDPCs) acts as a protective mechanism that promotes cell survival under adverse conditions through different signaling pathways. In this study, we examined whether LPS increases autophagy in hDPCs and investigated the role of mitogen-activated protein kinases signaling and nuclear factor κB (NF-κB) in this process. Read More
