Objective: Alzheimer's disease (ad) is a progressive and degenerative disorder of the central nervous system that is associated with cognitive and memory impairment. The main factors which have been implicated in neurodegeneration of ad are oxidative stress and cholinergic neurons dysfunction. Here, we examined the effects of auraptene, a novel acetylcholinesterase (AChE) inhibitor, on hydrogen peroxide (HO)-induced cell death in PC12 cells.

Background: Dysfunction of the cholinergic system and increased oxidative stress have a crucial role in cognitive disorders including Alzheimer's disease (AD). Here, we have investigated the protective effects of betanin, a novel acetylcholinesterase (AChE) inhibitor, on hydrogen peroxide (HO)-induced cell death in PC12 cells.

Methods And Results: The protective effects were assessed by measuring cell viability, the amount of reactive oxygen species (ROS) production, AChE activity, cell damage, and apoptosis using resazurin, 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA), Ellman method, lactate dehydrogenase (LDH) release, propidium iodide (PI) staining and flow cytometry, and Western blot analysis.

Alpha-bisabolol (α-bisabolol), an unsaturated monocyclic sesquiterpene alcohol, is known as one of the "most-used herbal constituents" in the world. Various therapeutic and biological properties of α-bisabolol in preventing oxidative stress, inflammatory disorders, infections, neurodegenerative diseases, cancers, and metabolic disorders have been reported. In this review, we evaluated new findings regarding the molecular mechanisms of α-bisabolol published from 2010 until 2021 in PubMed, Science Direct, and Scopus.

Due to many therapeutic effects, Ginger (Zingiber officinale) is the most widely used spice around the world, including in Iran. Due to its potent anti-inflammatory and antioxidant effects, ginger may protect against neurodegenerative disorders. Here, we investigated the effects of 6-gingerol (the main bioactive compound in ginger) on 6-hydroxydopamine (6-OHDA)-induced cell death in PC12 cells.

Background: Gamma-oryzanol (γ-oryzanol) is one of the rice bran oil (RBO) compounds, known as a principal food source throughout the world. In recent numerous experimental studies, γ-oryzanol has been revealed to have several useful pharmacological properties, such as anti-oxidant, anti-inflammatory, anti-cancer, anti-diabetic, ameliorating unpleasant menopausal symptoms, cholesterol-lowering, improving plasma lipid pattern, etc. Methods: In this study, we reviewed the scientific literature published up until 2020, which has evaluated the biological and pharmacological activity of gamma-oryzanol.

Background And Purpose: is one of the well-known herbal medicinal plants for antimicrobial, insecticidal, antioxidant, and antimalarial activities. The antiproliferative effects of dichloromethane extracts of () and and the petroleum ether extract of have been demonstrated previously on human cancerous cell lines. In the current study, further fractionation was carried out on the aforementioned extracts and their cytotoxic effects were evaluated on three human cancer cell lines; B16/F10, PC3, and MCF7.

Chaharmahal and Bakhtiari Province is one of the most important endemism states of the flora of Iran with a considerable plant species diversity. In the present study, the cytotoxic activity of 13 plant species grown in Chaharmahal and Bakhtiari have been evaluated on prostate (PC-3), breast (MCF-7), liver (HepG2), ovary (CHO), and melanoma (B16-F10) cancer cell lines. The cytotoxicity and apoptotic activity of methanol extracts was evaluated using resazurin reagent and flow cytometry of PI stained cells, respectively.

Neuroprotection using compounds with dual functions of anti-apoptotic and antioxidant effects fight against neurodegeneration. Vitamin K2 acts as a cofactor in many biochemical pathways, including sphingolipid synthesis in the nervous system, which is involved in many cellular events, including proliferation, differentiation, cellular communication, and alteration. This study aimed to investigate the protective effects of vitamin K2 in PC12 cells as an in vitro model of Parkinson's disease.

Objectives: The possible action of nonsteroidal anti-inflammatory drugs (NSAIDs) in the reduction of reactive oxygen species (ROS) and also as anti-apoptotic agents may suggest them as putative agents for the treatment of neurodegenerative diseases. This study was designed to explore some pathways alterations induced by NSAIDs following 6-hydroxydopamine (6-OHDA)-induced cell death in PC12 cells as an in vitro model of Parkinson's disease (PD) and to compare the effects of celecoxib, indomethacin and ibuprofen.

Materials And Methods: The cell viability, ROS content, glutathione (GSH) level, and apoptosis were measured using resazurin, dichlorofluorescein diacetate (DCFH-DA), 5,5'-dithiobis-2-nitrobenzoic acid (DTNB), propidium iodide (PI) and flowcytometry, real-time PCR and western blot.

Background: Besides the first-line medication for the treatment of type 2 diabetes, the growth inhibitory activity of metformin alone or in combination with conventional chemotherapeutics has been addressed on a panel of cell lines. In this study, we investigated the cytotoxicity and apoptosis of the metformin alone and in combination with dacarbazine in Raji and Ramos lymphoma cell lines.

Methods: Cell viability and apoptosis measured using resazurin assay, flow cytometry of PI stained cells and western blot analysis.
