Abstract null null Anticancer effect of resveratrol and the role of sodium/lithium/calcium exchanger in context with calcium ions are studied in human cervical cancer cell line. This therapeutic approach using siNCLX mediated gene silencing and drug therapy with resveratrol indicates the disruption of calcium homeostasis, increase in caspase (-3, 8, 9) mRNA expressions and DNA damage leading to apoptotic cell death. Monitoring the intracellular Ca2+ changes using fluo-4AM indicates highest rise in [Ca2+] level in sodium/lithium/calcium exchanger silenced group with five different stages, that is distinguishable based on the fluorescence intensity. In resveratrol treated and siNCLX + resveratrol treated groups no such cell staging differences were observed, despite uniform Ca2+ rise followed by decrease in the intensity. Integrating RNAi gene silencing of sodium/lithium/calcium exchanger with resveratrol can form the most interesting, efficient and promising therapeutic strategy in the treatment of cancer.

Covering: 1976 to 2020.Although constituting a limited chemical family, phytostilbenes represent an emblematic group of molecules among natural compounds. Ever since their discovery as antifungal compounds in plants and their ascribed role in human health and disease, phytostilbenes have never ceased to arouse interest for researchers, leading to a huge development of the literature in this field. Owing to this, the number of references to this class of compounds has reached the tens of thousand...

Nearly two decades since its discovery as one of the genes responsible for Wolf-Hirschhorn Syndrome (WHS), the primary function of the leucine-zipper EF-hand transmembrane 1 (LETM1) protein in the inner mitochondrial membrane (IMM) or the mechanism by which it regulates mitochondrial Ca2+ handling is unresolved. Meanwhile, LETM1 has been associated with the regulation of fundamental cellular processes such as development, cellular respiration and metabolism, and apoptosis. This mini-review summa...

Diabetes mellitus is a significant health problem that is caused by chronic hyperglycaemia as a result of inadequate insulin production or ineffective insulin action in the body. In recent years, many new pharmacological and non-pharmacological therapies have been developed for improving pancreatic insulin secretion and insulin resistance. Resveratrol is a natural and biologically active stilbenoid polyphenol present in various plant species and has the potential to benefit diabetes. The anti-di...

Abstract While the elderly segment of the population continues growing in importance, neurodegenerative diseases increase exponentially. Lifestyle factors such as nutrition, exercise, and education, among others, influence ageing progression, throughout life. Notably, the Central Nervous System (CNS) can benefit from nutritional strategies and dietary interventions that prevent signs of senescence, such as cognitive decline or neurodegenerative diseases such as Alzheimer’s disease and Parkinson’...

Cancer cells have increased energy requirements due to their enhanced proliferation activity. This energy demand is, among others, met by mitochondrial ATP production. Since the second messenger Ca2+ maintains the activity of Krebs cycle dehydrogenases that fuel mitochondrial respiration, proper mitochondrial Ca2+ uptake is crucial for a cancer cell survival. However, a mitochondrial Ca2+ overload induces mitochondrial dysfunction and, ultimately, apoptotic cell death. Because of the vital impor...

Already in the early 1960s, researchers noted the potential of mitochondria to take up large amounts of Ca2+. However, the physiological role and the molecular identity of the mitochondrial Ca2+ uptake mechanisms remained elusive for a long time. The identification of the individual components of the mitochondrial calcium uniporter complex (MCUC) in the inner mitochondrial membrane in 2011 started a new era of research on mitochondrial Ca2+ uptake. Today, many studies investigate mitochondrial C...

In this study, the DAPI staining is firstly reported for use in the identification of hepatic carcinoma cells based on hyperspectral microscopy. Nuclei in cancer cells usually contain more aneuploidies than that in normal cells, leading to the change of DNA content. Here, we stain hepatic carcinoma tissues and normal hepatic tissues with 4’,6-diamidino-2-phenylindole (DAPI) which is sensitive to the DNA content as a fluorochrome binds to DNA. Consequently, the difference in DNA content between h...

Abstract Aging is characterized by a progressive loss of physiological integrity. One common denominator is the increase of reactive oxygen species (ROS) caused by inhibition of important antioxidant pathways. Resveratrol is a polyphenol known for its potent antioxidant activity. However, antioxidant pathways activated by them change with aging. The objective of our study was to verify the antioxidant effect of resveratrol in an oxidative stress environment in Human Mononuclear Cells (PBMC) from...

Calpains are calcium-dependent proteases activated in apoptotic cell death and neurodegeneration. Friedreich Ataxia is a neurodegenerative rare disease caused by frataxin deficiency, a mitochondrial protein. Dorsal root ganglion (DRG) sensory neurons are among the cellular types most affected in this disease. We have previously demonstrated that frataxin-deficient DRGs show calpain activation, alteration in calcium levels and decreased content of the Na(+)/Ca(2+) exchanger (NCLX). This transport...

Drug induced nephrotoxicity commonly occurs in hospitalized patients and sometimes may complicate treatment outcome, especially in critically ill patients. No universal prophylactic agent is available yet to protect against drug related nephrotoxicity. Many modalities have been applied with different successes. Polyphenolic compounds such as resveratrol have been used both in-vitro and in vivo to prevent drug induced nephrotoxicity. Resveratrol have several antioxidant, antiplatelet and nitric o...
