Hipertensión pulmonar: señalización mediada por canales de calcio, dianas farmacológicas presentes y futuras

Rev. méd. Chile; 151 (6), 2023
La hipertensión arterial pulmonar se caracteriza por una presión arterial pulmonar media y resistencia vascular pulmonar elevadas y remodelado patológico de las arterias pulmonares. La entrada de calcio desde el espacio extracelular al intracelular a través de canales dependientes e independientes de...

Neuro-protective effect of Linalool against spinal cord injury in rats and the mechanism involved

The current study was conducted to determine the neuroprotective role and mechanism of action of Linalool (LIN) in SCI. The SCI in Sprague-Dawley (SD) rats was induced by weight-drop contusion model. Results of the suggested that LIN showed improvement in the locomo...

Edaravone improves the post-traumatic brain injury dysfunction in learning and memory by modulating Nrf2/are signal pathway

Clinics; 76 (), 2021
OBJECTIVES: To investigate the molecular mechanism of edaravone (EDA) in improving the post-traumatic brain injury (TBI) dysfunction in learning and memory. METHODS: In vitro and in vivo TBI models were established using hydrogen peroxide (H2O2) treatment for hippocampal nerve stem cells (NSCs) and surg...

Lotus leaf flavonoids induce apoptosis of human lung cancer A549 cells through the ROS/p38 MAPK pathway

Biol. Res; 54 (), 2021
BACKGROUND: Leaves of the natural plant lotus are used in traditional Chinese medicine and tea production. They are rich in flavonoids. METHODS: In this study, lotus leaf flavonoids (LLF) were applied to human lung cancer A549 cells and human small cell lung cancer cells H446 in vitro to verify the effec...

Diosmetin inhibits cell proliferation and promotes apoptosis through STAT3/c-Myc signaling pathway in human osteosarcoma cells

Biol. Res; 54 (), 2021
BACKGROUND: Diosmetin is a bioflavonoid compound naturally abundant in citrus fruits. It is found to perform a variety of activities, while its antitumor property in osteosarcoma, a malignant tumor with unmet clinical treatment, remained unknown. METHODS: Colony formation assay, cell cycle analysis and a...

Aliskiren attenuates cardiac dysfunction by modulation of the mTOR and apoptosis pathways

Braz. j. med. biol. res; 53 (2), 2020
Aliskiren (ALS) is well known for its antihypertensive properties. However, the potential underlying the molecular mechanism and the anti-hypertrophic effect of ALS have not yet been fully elucidated. The aim of the present study was to investigate the role of ALS in mammalian target of rapamycin (mTOR) ...

Edaravone alleviates cell apoptosis and mitochondrial injury in ischemia-reperfusion-induced kidney injury via the JAK/STAT pathway

Biol. Res; 53 (), 2020
BACKGROUND: Kidney ischemia-reperfusion injury is a common pathophysiological phenomenon in the clinic. A large number of studies have found that the tyrosine protein kinase/signal transducer and activator of transcription (JAK/STAT) pathway is involved in the development of a variety of kidney diseases ...

Biochanin A attenuates myocardial ischemia/reperfusion injury through the TLR4/NF-κB/NLRP3 signaling pathway

Acta cir. bras; 34 (11), 2019
Abstract Purpose: Myocardial ischemia/reperfusion (Ml/R) injury is a leading cause of damage in cardiac tissues, with high rates of mortality and disability. Biochanin A (BCA) is a main constituent of Trifolium pratense L. This study was intended to explore the effect of BCA on Ml/R injury and explore t...

Alpha-hederin induces the apoptosis of oral cancer SCC-25 cells by regulating PI3K/Akt/mTOR signaling pathway

BACKGROUND: Oral cancer is one of the common malignant tumors of the head and neck. However, current treatments have numerous side effects, and drugs from natural sources may have better therapeutic potential. This research investigated the induction of apoptosis by α-hederin (α-HN), a constituent of P...

The effect of anesthetic preconditioning with sevoflurane on intracellular signal-transduction pathways and apoptosis, in a lung autotransplant experimental model

Rev. bras. anestesiol; 69 (1), 2019
Abstract Background: Anesthetic pre-conditioning attenuates inflammatory response during ischemia-reperfusion lung injury. The molecular mechanisms to explain it are not fully understood. The aim of our investigation was to analyze the molecular mechanism that explain the anti-inflammatory effects of an...
