Regulation and properties of glucose-6-phosphate dehydrogenase: A review

Glucose-6-phosphate dehydrogenase (G6PD) is the key enzyme of the pentose phosphate pathway that catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolactone in presence of NADP+. G6PD is an enzyme of vital importance because of its role in various haemolytic disorders and its potential as a regulator for various biosynthetic pathways. NADPH is the important product of the reaction and is used for the...

Detrimental impact of triplet oxygen in biosphere

Oxygen is essential for the existence of all forms of life since it is an important constituent of almost all biologically important compounds including DNA and serves as blood purifier. Simultaneously oxygen also induces a number of degradation processes through the generation of reactive oxygen species like superoxide radical anion, singlet oxygen, hydroxyl radical, hydrogen peroxide etc. The reactive oxygen species...

Comparative study of different protocols for isolation of RNA from polysaccharides and polyphenolics rich plant tissues

The isolation of high quality ribonucleic acid (RNA) from plant has been a difficult problem due to presence of high amount of polysaccharides, polyplenolics and nucleases that mediate RNA degradation. After comparative analysis of four popular protocols for RNA isolation, a modified method was developed which gave maximum yield with purity. Modified method is not only suitable for the isolation of intact RNA from...

Abundant CD4 Th-2 cytokine stimulation by medicinal plant Pongamia pinnata Linn. on human peripheral blood mononuclear cell (PBMC)

Immune cells produce cytokines in response to various stimuli. The initial cytokine milieu at which immune cells interact have a positive impact on the outcome of the immune response generated. Modulations or polarizations of cytokines are known to affect the outcome of the disease. Immunotherapy is a novel approach to combat cytokine mediated diseases and several medicinal plants are shown to possess immune modulatory...
