Ropivacaine promotes apoptosis of hepatocellular carcinoma cells through damaging mitochondria and activating caspase-3 activity

Biol. Res; 52 (), 2019
BACKGROUND: Recent evidences indicated that some local anaesthetic agents played a role in inhibiting the proliferation of cancer cells; Whether ropivacaine is able to promote apoptosis of hepatocellular carcinoma (HCC) cells is still unclear. The aim of this study was to investigate the effect of ropiva...

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Psoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic prolifer...

Derlin1 functions as an oncogene in cervical cancer via AKT/mTOR signaling pathway

Biol. Res; 52 (), 2019
BACKGROUND: Cervical cancer (CC) ranks third in the morbidity and mortality of female cancer around the world. Derlin1 has been found to be overexpressed in several human cancers. However, it is still unclear about its roles in CC. The research aims to explore the relationship between Derlin1 and CC. MET...

Vitexin induces apoptosis through mitochondrial pathway and PI3K/Akt/mTOR signaling in human non-small cell lung cancer A549 cells

Biol. Res; 52 (), 2019
BACKGROUND: Currently, the prognosis of patients with non-small cell lung cancer (NSCLC) remains dismal; hence, it is critical to identify effective anti-NSCLC agents with limited side effects. This study aimed to evaluate the therapeutic potential of flavonoid compound vitexin in human NSCLC cells and t...

Intestinal transcriptional profiling reveals fava bean-induced immune response in DBA/1 mice

Biol. Res; 52 (), 2019
BACKGROUND: Fava beans (FBs) have long been used as food, and their principal disadvantage is derived from their haemotoxicity. We hypothesized that FB ingestion alters the intestinal gene expression pattern, thereby inducing an immune response. RESULTS: In-depth sequence analysis identified 769 differen...

IRF2-INPP4B-mediated autophagy suppresses apoptosis in acute myeloid leukemia cells

Biol. Res; 52 (), 2019
BACKGROUND: The present study aimed to investigate the underlying role of interferon-regulatory factor 2 (IRF2)-inositol polyphosphate-4-phosphatase, type-II (INPP4B) axis in the regulation of autophagy in acute myeloid leukemia (AML) cells. METHODS: Quantitative real time PCR (QRT-PCR) and western blot ...

Identification of the molecular mechanisms associated with acute type A aortic dissection through bioinformatics methods

Braz. j. med. biol. res; 52 (11), 2019
Aortic dissection is characterized by the redirection of blood flow, which flows through an intimal tear into the aortic media. The purpose of this study was to find potential acute type A aortic dissection (AAAD)-related genes and molecular mechanisms by bioinformatics. The gene expression profiles of G...

Oxiracetam ameliorates cognitive deficits in vascular dementia rats by regulating the expression of neuronal apoptosis/autophagy-related genes associated with the activation of the Akt/mTOR signaling pathway

Braz. j. med. biol. res; 52 (11), 2019
Oxiracetam (ORC) is a commonly used nootropic drug for improving cognition and memory impairments. The therapeutic effect and underlying mechanism of ORC in vascular dementia (VaD) treatment remain unknown. In this study, 3-month-old male Sprague-Dawley rats with permanent bilateral common carotid artery...

Schizandrin A exerts anti-tumor effects on A375 cells by down-regulating H19

Braz. j. med. biol. res; 52 (10), 2019
Malignant melanoma (MM) is one of the malignant tumors with highly metastatic and aggressive biological actions. Schizandrin A (SchA) is a bioactive lignin compound with strong anti-oxidant and anti-aging properties, which is stable at room temperature and is often stored in a cool dry place. Hence, we i...

The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway

Braz. j. med. biol. res; 52 (10), 2019
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium veri...
