Chemotherapeutic and Antiproliferative Effect of Purified Protein from Marine Catfish Tachysurus Dussumieri on Human Colon Cancer Cell Line.

The present study aimed to investigate the purified protein from the epidermal mucus of marine catfish Tachysurus dussumieri on the human colon cancer cell line. The bioactive protein was purified with the Anion exchange chromatography and the collected fractions were then tested to assess cell viability in HT 29 cells through the MTT assay. The most responding active purified protein fraction (PPF III) was characterized with the MALDI-TOF/MS it shared a similar homology and sequence with 90% of antimicrobial peptides from external secretions of amphibians.

Ingestion of microplastics and its potential for causing structural alterations and oxidative stress in Indian green mussel Perna viridis- A multiple biomarker approach.

The present study has investigated the distribution of microplastics in sediment and its impact on histological, ultrastructural, and oxidative stress mechanisms in Perna viridis (P. viridis) from Kasimedu, Chennai, India. The results confirmed that fibers were the predominant type of microplastics observed, followed by spheres, flakes, sheets, and fragments.

Antiproliferative and antioxidant properties of nematocysts crude venom from jellyfish against human cancer cell lines.

This study aimed to investigate the antiproliferative and antioxidant properties of crude venom from the nematocyst of Jellyfish on human lung cancer (A549) and liver cancer (HepG2) cell lines. The prepared crude venom was subjected to analyses of the biochemical constituents, protein profiles, antioxidant and anticancer activities by standard methods. The extracted venom was pale-yellow in color and viscous/sticky.

Anticancer effect of purified polysaccharide from marine clam Donax variabilis on A549 cells.

The marine invertebrates are one of the main leads to the derivation of anticancer compounds. The present investigation was to explore the anticancer effect of a potentially active polysaccharide fraction from marine clam Donax variabilis on human lung cancer cells (A549). A polysaccharide was purified from the whole tissue of D.

A novel phytosterol isolated from Datura inoxia, RinoxiaB is a potential cure colon cancer agent by targeting BAX/Bcl2 pathway.

Plant sterols have been widely used as chemotherapeutic agents for colorectal cancer for years together. In this study, a novel phytosterol was isolated and characterized from the leaf extract of a medicinal plant, Datura inoxia and was coined as RinoxiaB (RB). This phytosterol was observed to have antiproliferative activity against human colon adenocarcinoma cells, HCT 15.

A focus on resveratrol and ocular problems, especially cataract: From chemistry to medical uses and clinical relevance.

Low vision and blindness are important health problems that affect millions of people throughout the world. The most common and important pathologies are diabetic retinopathy, age-related macular degeneration, glaucoma as well as cataracts. The latter consists of an opacification of the lens of the eye which impedes the passage of light and represents one of the most important causes of vision loss.

Apoptosis in liver cancer (HepG2) cells induced by functionalized gold nanoparticles.

An ethnopharmacological approach for biosynthesis of gold nanoparticles is being demonstrated using seed coat of Cajanus cajan. Medicinal value of capping molecule investigated for anticancer activity and results disclose its greater potential. The active principle of the seed coat [3-butoxy-2-hydroxypropyl 2-(2,4-dihydroxyphenyl) acetate] is elucidated.

Synthesis and characterization of silver nanoparticles using crystal compound of sodium para-hydroxybenzoate tetrahydrate isolated from Vitex negundo. L leaves and its apoptotic effect on human colon cancer cell lines.

Metallic nanoparticles are major concern, particularly silver nanoparticles (AgNPs) are used in various applications. In the present investigation, we report a novel strategy with biological approach for synthesis of AgNPs using sodium para-hydroxybenzoate tetrahydrate (SPHT) isolated from Vitex negundo leaves. The synthesized SPHT-AgNPs were characterized by UV-vis spectroscopy, high resolution transmission electron microscopy (HRTEM) with selected area electron diffraction (SAED) pattern, field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray spectroscopy (EDX), zeta potential and Fourier transform infrared spectroscopy (FT-IR) analysis.

Toxicity effect of silver nanoparticles in brine shrimp Artemia.

The present study revealed the toxic effect of silver nanoparticles (AgNPs) in Artemia nauplii and evaluated the mortality rate, hatching percentage, and genotoxic effect in Artemia nauplii/cysts. The AgNPs were commercially purchased and characterized using field emission scanning electron microscope with energy dispersive X-ray spectroscopy. Nanoparticles were spherical in nature and with size range of 30-40 nm.

Galangin, a dietary flavonol inhibits tumor initiation during experimental pulmonary tumorigenesis by modulating xenobiotic enzymes and antioxidant status.

The aim of present study was to elucidate anti-initiating efficacy of galangin against benzo(a)pyrene (B(a)P)-induced lung carcinogenesis in male Swiss albino mice. Therefore, the activities of xenobiotic metabolic enzymes such as phase I and II were examined in lung as well as liver tissues (to compare the effects between target and non-target organs). Besides, the activities/levels of tissue marker enzymes, antioxidants, lipid peroxidation (LPO), cytochrome P450 1A1 (CYP1A1) expressions and histological observation of lungs were also analyzed.

Ameliorative effect of ferulic acid against renal injuries mediated by nuclear factor-kappaB during glycerol-induced nephrotoxicity in Wistar rats.

The pathogenesis of glycerol-induced myoglobinuric acute renal failure involves ischemia, vascular congestion and reactive oxygen metabolites. In this study, we have investigated for the first time, the role of ferulic acid in attenuating glycerol-induced nephrotoxicity. Male Wistar rats were injected intramuscularly with 8 mL/kg body weight of 50% glycerol, glycerol + ferulic acid at the dose of 5, 10, 15, 20 and 25 mg/kg body weight.

Biomarkers of metal toxicity and histology of Perna viridis from Ennore estuary, Chennai, south east coast of India.

Distribution of heavy metals and its associated histological perturbations were studied in the soft tissues of Perna viridis collected from Ennore estuary and compared with the less polluted Kovalam coast. The concentration of copper, lead, zinc, cadmium, manganese and iron were quantified in gills, digestive gland and adductor muscle. The results showed marked differences between the two sites as well as significant variations within the tissues.
