Pgc-1α Promotes Phosphorylation, Inflammation, and Apoptosis in H9c2 Cells During the Early Stage of Lipopolysaccharide Induction.

Inflammation 2021 Apr 13. Epub 2021 Apr 13.

Emergency Department, Shenzhen Second People's Hospital, Shenzhen University First Affiliated Hospital, No.3002 Sungang West Road, Shenzhen, 518035, Guangdong, People's Republic of China.

Cardiac dysfunction in severe sepsis is associated with increased mortality. However, the molecular mechanisms underlying septic heart dysfunction remain unclear. Expression of peroxisome proliferator-activated receptor-γ coactivator 1α (Pgc-1α), concentrations of inflammatory factors, and activation of the nuclear factor kappa-B (NF-κB) signaling pathway were examined in H9c2 cells after a 24-h lipopolysaccharide (LPS) stimulation period using qPCR, enzyme-linked immunosorbent assays (ELISAs), and western blots (WBs), respectively.

Photobiomodulation Therapy on Myocardial Infarction in Rats: Transcriptional and Posttranscriptional Implications to Cardiac Remodeling.

Lasers Surg Med 2021 Apr 13. Epub 2021 Apr 13.

Universidade Nove de Julho, Rua Vergueiro 249, Liberdade, São Paulo, SP, 01504-001, Brazil.

Background And Objectives: Induction of myocardial infarction (MI) in rats by occlusion of the left anterior descending coronary artery is an experimental model used in research to elucidate functional, structural, and molecular modifications associated with ischemic heart disease. Photobiomodulation therapy (PBMT) has become a therapeutic alternative by modulating various biological processes eliciting several effects, including anti-inflammatory and pro-proliferative actions. The main objective of this work was to evaluate the effect of PBMT in the modulation of transcriptional and post-transcriptional changes that occurred in myocardium signal transduction pathways after MI.

PRIMA‑1 induces autophagy in colorectal cancer cells through upregulation of the mTOR/AMPK‑ULK1‑Vps34 signaling cascade.

Oncol Rep 2021 May 13;45(5). Epub 2021 Apr 13.

Department of Gastroenterology, The Affiliated Suzhou Hospital of Nanjing Medical University, Suzhou, Jiangsu 215001, P.R. China.

p53‑reactivation and induction of massive apoptosis‑1, APR‑017 methylated (PRIMA‑1; APR246) targets mutant p53 to restore its wild‑type structure and function. It was previously demonstrated that PRIMA‑1 effectively inhibited the growth of colorectal cancer (CRC) cells in a p53‑independent manner, and distinctly induced apoptosis by upregulating Noxa in p53‑mutant cell lines. The present study including experiments of western blotting, acridine orange staining and transmission electron microscopy revealed that PRIMA‑1 induced autophagy in CRC cells independently of p53 status.

CREB stimulates GPX4 transcription to inhibit ferroptosis in lung adenocarcinoma.

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

Shanghai Institute of Thoracic Oncology, Shanghai Chest Hospital, Shanghai Jiao Tong University, Shanghai 200030, P.R. China.

Ferroptosis is a new form of regulated cell death and closely related to cancer. However, the mechanism underlying the regulation of ferroptosis in lung adenocarcinoma (LUAD) remains unclear. IB, IHC and ELISA were performed to analyze protein expression. Read More

LncRNA NR024118 is downregulated in sepsis and inhibits LPS‑induced apoptosis of cardiomyocytes.

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

ICU Department, Guangxi Zhuang Autonomous National Hospital, Nanning, Guangxi Zhuang Autonomous Region 530001, P.R. China.

It has been reported that lncRNA‑NR024118 can suppress lipopolysaccharide (LPS)‑induced inflammatory responses, which promote sepsis. The present study aimed to investigate the involvement of NR024118 in sepsis. Research subjects included 82 patients with sepsis without myocardial dysfunction (MD), 35 patients with sepsis with MD and 82 healthy controls. Read More

Apoptosis-like cell death upon kinetoplastid induction by compounds isolated from the brown algae Dictyota spiralis.

Parasit Vectors 2021 Apr 12;14(1):198. Epub 2021 Apr 12.

Instituto Universitario de Enfermedades Tropicales y Salud Pública de Canarias, Universidad de La Laguna (ULL), Avda. Astrofísico Fco. Sánchez S/N, 38203, La Laguna, Tenerife, Spain.

Background: The in vitro activity of the brown seaweed Dictyota spiralis against both Leishmania amazonensis and Trypanosoma cruzi was evaluated in a previous study. Processing by bio-guided fractionation resulted in the isolation of three active compounds, classified as diterpenes. In the present study, we performed several assays to detect clinical features associated to cell death in L. Read More

RUNX2 promotes vascular injury repair by activating miR-23a and inhibiting TGFBR2.

Ann Transl Med 2021 Mar;9(5):363

Department of General & Vascular Surgery, Xiangya Hospital, Central South University, Changsha, China.

Background: Previous evidence has suggested that the transcription factor, runt-related transcription factor 2 (RUNX2), promotes the repair of vascular injury and activates the expression of microRNA-23a (miR-23a). TGF-β receptor type II (TGFBR2) has been found to mediate smooth muscle cells (SMCs) following arterial injury. However, the interactions among RUNX2, miR-23a and TGFBR2 in vascular injury have not been investigated thoroughly yet. Read More
