Abstract

Cardiac hypertrophy is frequently accompanied by ischemic heart disease. Actinidia chinensis planch polysaccharide (ACP) is the main active compound from Actinidia chinensis planch. In the present study, a cardiac hypertrophy model was produced by treating cells with Angiotensin II (Ang II), which was used to investigate whether ACP protected against cardiac hypertrophy in vitro. It was demonstrated that ACP alleviated Ang II‑induced cardiac hypertrophy. In addition, pretreatment with ACP prior to hypoxic culture reduced the disruption of the mitochondrial membrane potential as investigated by flow cytometry. Cell Counting kit‑8 analysis demonstrated that ACP maintained the cell viability of cardiomyocytes. The flow cytometric analysis revealed that ACP inhibited hypoxia‑induced apoptosis in cardiomyocytes treated with Ang II. Additionally, reverse transcription‑polymerase chain reaction and western blotting assays demonstrated that ACP decreased the expression of apoptosis‑associated genes including apoptosis‑inducing factor mitochondria associated 1, the cysteinyl aspartate specific proteinases caspases‑3/8/9, and cleaved caspases‑3/8/9. The results of the present study also demonstrated that ACP inhibited the activation of t...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

Cardiomegaly

Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.
