The search for a nontoxic radioprotector has not yielded any promising results. Many antioxidant compounds, though effective under in vitro conditions as radioprotectors, have failed under in vivo settings due to their toxicity. The Indian medical system of Ayurveda uses a variety of plants with antioxidant potential, and these may be harboring molecules with radioprotective properties. In the present work, the radioprotective property of Nardostachys jatamansi was investigated. A hydro-alcoholic extract of this plant provided protection to the cellular DNA and membrane from 4 Gy gamma radiation...

The eukaryotic cell cycle via mitogen-activated protein kinase (MAPK) has been considered as an effective signaling cascade pathway for anticancer therapy. In addition to the MAPK signaling pathway, the Rat Sarcoma Virus (Ras)/Rapidly Accelerated Fibrosarcoma (Raf)/MAPK-ERK kinase (MEK)/extracellular signal-regulated kinase (ERK) pathway is a signaling cascade that has a crucial role to play in cell survival and development of cancer, especially breast cancer. Novel drugs and clinical trials need to be investigated, taking into consideration the already studied genetic defects related to genesis of tumors in certain populations...

Microsatellite instability (MSI) implies the deletion of mismatch repair genes caused by DNA methylation or gene mutation. MSI is a good predictor for efficacy of 5-fluorouracil (FU)-based chemotherapy in the treatment of colorectal cancer. Some gastric cancer studies have reported that MSI has no apparent impact on prognosis after patients receive 5-FU-based adjuvant chemotherapy. However, other studies suggest that high-frequency MSI (MSI-H) status reduced survival in patients receiving 5-FU-based adjuvant chemotherapy...

All-trans-retinoic acid (ATRA) is a potent inducer of cellular differentiation, growth arrest, and apoptosis as well as a front-line therapy for acute promyelocytic leukemia (APL). The present study provides evidence that induction of autophagy is required for ATRA to induce differentiation of APL (NB4) cells into granulocytes. ATRA treatment causes ~12-fold increase in the number of acidic vesicular organelles and induces marked up-regulation of LC3-II, autophagy-related 5 (ATG5), and Beclin-1. Transmission electron microscopy (TEM) revealed a decrease in mitochondria and ATRA-induced differentiation...

Liver cancer is the fifth commonly occurring cancer worldwide with the annual death rate of 9.1%. Hepatocellular carcinoma is the most frequent kind of primary liver cancer and occurs mostly in patients with chronic liver disease and cirrhosis. Because the cancer is generally detected only in the later stages, it is often treated with therapies such as radiation, ablation, and chemotherapy, which produces serious side effects and has a low recovery rate. Therefore, researchers are now focused on herbal-based drugs with increased efficacy and with no side effects to treat cancer...

The hypoxic tumor microenvironment is one of the major causes of the enhanced chemoresistant and radioresistant behavior of cancer cells. Therefore, the hypoxia-induced factor (HIF) pathway can be endorsed, for not only the malignant phenotype of the cells, but also its metastatic potential. Many drugs targeting the HIF pathways have failed in the clinical setting to demonstrate therapeutic efficacy. Such failures occur due to lack of specificity or redundancy in the complexity of tumor signaling/metabolism that can overcome the inhibitory effects...

Hexavalent chromium [Cr(VI)] is a lung carcinogen and its complete mechanism of action remains to be investigated. Metabolic reprogramming of key energy metabolism pathways (e.g., increased anaerobic glycolysis in the presence of oxygen or "Warburg effect", dysregulated mitochondrial function, and lipogenesis) are important to cancer cell and tumor survival and growth. In our current understanding of Cr(VI)-induced carcinogenesis, the role for metabolic reprogramming remains unclear. In this study, we treated human lung epithelial cells (BEAS-2B) with Cr(VI) for 6 months and obtained malignantly transformed cells from an isolated colony grown in soft agar...

Induced pluripotent stem cells (also called iPSCs) are somatic cells reprogrammed by overexpressing four nuclear transcriptional factors containing Sox2, Klf4, c-myc and Oct4 is the one of research hotspots. Its pluripotency, self-renewal capacity and wide accessibility to donor tissues have made possible the means for modified regenerative medicine. They are considered a possible basis of healthy tissue to cure diseases, like ophthalmic diseases, degenerative diseases, age-related macular degeneration (AMD), are primarily because of the weakening capability of photoreceptor cells, retinal ganglion cells (RGCs), retinal pigmented epithelium (RPE) or other retinal cells...

Chronic atrophic gastritis is a generally asymptomatic condition of great importance because it develops into gastric cancer in a number of patients. It is described as an atrophy of the gastric mucosa. There are two types of atrophic gastritis: a gastric body predominant type in patients with infection of Helicobacter pylori, and an autoimmune type, limited to the gastric body and fundus. The autoimmune type is quite rare and affects people of all ethnicities. Globally, H. pylori infection is very common and is considered a class I carcinogen due to the large number of patients who subsequently develop gastric cancer...
