Enhanced Production of Astaxanthin and Zeaxanthin by Paracoccus Sp. LL1 Through Random Mutagenesis
Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Astaxanthin, a high‐value carotenoid with potent antioxidant and anti‐inflammatory activities, is increasingly in demand in various industries. This study reports the successful enhancement of astaxanthin and zeaxanthin production in Paracoccus sp. LL1 through random mutagenesis using ethyl methanesulfonate (EMS).

Antimutagenic effect of ellagic acid and its effect on the immune response in mice
Czech Journal of Food Sciences, 2002 Using the Ames bacterial mutagenicity test and an in vivo micronucleus test, we investigated the antigenotoxic effect of ellagic acid on the genotoxicity of three mutagens: amino-methylimidazo-quinoline (IQ), aflatoxin B1 (AFB1), and N-nitroso-N ...

Intergenerational Enlargement of Human Organs as a Driver of Increased Cancer Risk?
BioEssays, EarlyView.Identifying the environmental factors and associated mechanisms driving increased cancer incidence in younger generations is a matter of great urgency. Here, we propose and discuss a new potential mechanism: larger organ sizes in younger individuals resulting from intergenerational differences in lifestyle, diet, and environmental exposures.

Environmental and Molecular Mutagenesis, EarlyView.Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Meat-cooking mutagens and risk of renal cell carcinoma
British Journal of Cancer, 2011 Background:High-temperature cooked meat contains two families of carcinogens, heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). Given the kidneys’ role in metabolism and urinary excretion of these compounds, we investigated meat ...

EFFECT OF ETHYL METHANESULFONATE (EMS) AND N-NITROSE-N´-ETHYL UREA (ENU) ON CALLUS GROWTH OF COMMON BEAN [PDF]
Journal of Central European Agriculture, 2005 Infl uence of ethyl methanesulfonate (EMS) and N-nitrose-N´-ethyl urea (ENU) mutagenic treatments was investigated on three time sub-cultured calli obtained from leaf petiole explants of 7-day old sterile plants.
