Aim: To determine the relation between serum microRNAs and apoptotic markers as regards development of HCC to understand the underlying mechanism of HCV related hepatocarcinogenesis.
Patients And Methods: A total of 65 serum samples (25 samples from controls, 20 samples from hepatitis and 20 samples from HCC patients) were collected for miRNAs (mir 21, mir 199-a, and mir 155) detection. Human Programmed cell death protein-4 (PDCD-4) and Human Cytochrome-C (CYT-C) were determined.
Results: miRNAs 21 and 155 were over expressed in sera of patients with HCC compared to patients with chronic hepatitis (p < 0.0001). While serum means values of miR 199a was significantly decreased among HCC group patients when compared to patients with chronic hepatitis (p < 0.0001). The serum levels of PCDC4 and CYTC were increased in patients with HCC when compared to chronic hepatitis patients. They were also increased in patients with chronic hepatitis when compared to controls (p < 0.05, significant). There was direct correlations between apoptotic markers and oncomirs miRNAs 21 and 155 while apoptotic markers were inversely correlated with miRNA 199-a.
Conclusion: Both microRNAs and apoptotic markers have roles in HCC pathogenesis. It seems that oncogenic microRNAs induce liver carcinogenesis in HCV patients irrespective of suppression of apoptosis.

Background: Alzheimer's disease (AD) is the foremost cause of global dementia, also characterized by retinal changes involving Aβ, hyperphosphorylated-tau (p-tau), neuronal degeneration, and tissue atrophy. Mitochondrial-driven reactive oxygen species (ROS) production, linked to synaptic dysfunction, is common to various neurodegenerative conditions, including AD. Despite synaptic dysfunction being an early predictor of cognitive decline in AD, its occurrence in the AD retina is unexplored.

Background: Sporadic Alzheimer's disease (sAD) is the most prevalent type of dementia, characterized by progressive neurodegeneration. Intracerebroventricular (ICV) administration of streptozotocin (STZ) serves as a model for sAD, inducing neurodegeneration through oxidative stress, apoptotic damage, mitochondrial dysfunction, and neuroinflammation. Fenchone, a monoterpenoid, has been reported to possess neuroprotective properties by attenuating oxidative stress, acetylcholinesterase activity, mitochondrial dysfunction and neuroinflammation.

Background: Alzheimer's disease (AD) is characterized by the accumulation of amyloid-beta (Aβ) in the extracellular space, which leads to various adverse effects such as oxidative stress, neuroinflammation, mitochondrial dysfunction, tau phosphorylation, synapse loss, and neurodegeneration. Therefore, therapeutic interventions that can reduce Aβ-toxicity and slow down the progression of cognitive dysfunction in AD have significance. One promising approach is to use extracellular vesicles (EVs) that are released by neural stem cells (NSCs) derived from human induced pluripotent stem cells (hiPSCs).

Introduction: Dl-3-n-butylphthalide (NBP), a small molecular compound extracted from celery seeds, has been shown to exhibit diverse pharmacological activities, including anti-inflammatory, antioxidative, and anti-apoptotic effects. Recent studies have highlighted its efficacy in treating various cardiovascular conditions, such as myocardial infarction, hypertrophy, heart failure, and cardiotoxicity. This study aimed to investigate whether NBP could alleviate cardiac dysfunction and injury following hemorrhage-induced cardiac arrest (HCA) in a porcine model and elucidate its potential mechanisms.

The present study aims to explore the anticancer efficacy of Diosmin by inducing mitochondrial-mediated apoptosis in human epidermoid carcinoma cells (Hep-2). This is done by cell line assays and studying crucial inflammatory and apoptotic signaling molecules. The cytotoxicity property of Diosmin was evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay.
