Phosphoinositide signaling has been implicated in the regulation of numerous cellular processes including cytoskeletal dynamics, cellular motility, vesicle trafficking, and gene transcription. Studies have also shown that nuclear phosphoinositide(s) regulates processes such as mRNA export, cell cycle progression, gene transcription, and DNA repair. We have(More)
In leguminous plants, nitrogenase that catalyzes anaerobic symbiotic nitrogen fixation is protected by the sequestration of O2 by Leghemoglobin (LegH). The modulation of the oxygen binding capacity of Hemoglobin (Hb) by different post-translational modifications is well studied; whereas similar studies on LegH's O2 binding are not yet benchmarked. Our(More)
Melanoma is one of the most aggressive forms of cancer, usually resistant to standard chemotherapeutics. Despite a huge number of clinical trials, any success to find a chemotherapeutic agent that can effectively destroy melanoma is yet to be achieved. Para-phenylenediamine (p-PD) in the hair dyes is reported to purely serve as an external dyeing agent.(More)
Diabetes (Type I and Type II) which affects nearly every organ in the body is a multi-factorial non-communicable disorder. Hyperglycemia is the most characteristic feature of this disease. Loss of beta cells is common in both types of diabetes whose detailed cellular and molecular mechanisms are yet to be elucidated. As this disease is complex,(More)
Phosphatidylinositol 4 phosphate 5 kinase 1α (PIP5K) is mainly localized in the cytosol and plasma membrane. Studies have also indicated its prominent association with nuclear speckles. The exact nature of this nuclear pool of PIP5K is not clear. Using biochemical and microscopic techniques, we have demonstrated that the nuclear pool of PIP5K is modified by(More)
Visceral leishmaniasis, a vector-borne tropical disease that is threatening about 350 million people worldwide, is caused by the protozoan parasite Leishmania donovani. Metalloids like arsenic and antimony have been used to treat diseases like leishmaniasis caused by the kinetoplastid parasites. Arsenic (III) at a relatively higher concentration (30 μg/mL)(More)
