Phytosphingosine is a long chain sphingoid base that occurs broadly in yeast, plants and animals including mammals. In yeast it is involved in mediating the heat stress response, perhaps through activation of the AGC-type protein kinases, Pkh1, Pkh2, Ypk1, Ypk2, and Sch9. It is proapoptotic in human cancer cell lines. PHS induces ΔΨm and release of cytochrome c from mitochondria either directly or through activation of p38 MAPK pathway. This leads to activation of caspase 9 followed by activation of caspase 3 and programmed cell death.

To review and summarize evidence on the role of diet and lifestyle factors and prostate cancer progression, with a specific focus on habits after diagnosis and the risk of subsequent disease recurrence, progression, or death. Given the well-documented heterogeneity of
Dementia risk in women is higher than in men, but the molecular neuropathology of this gender difference remains poorly defined. In this study, we used unbiased, discovery-driven quantitative proteomics to assess the molecular basis of gender influences on risk of

The Consortium of Metabolomics Studies (COMETS) was established in 2014 to facilitate large-scale collaborative research on the human metabolome and its relationship with disease etiology, diagnosis, and prognosis. COMETS comprises 47 cohorts from Asia, Europe, North America, and South America
Cleavage of mutant huntingtin (HTT) is an essential process in Huntington's disease (HD), an inherited neurodegenerative disorder. Cleavage generates N-ter fragments that contain the polyQ stretch and whose nuclear toxicity is well established. However, the functional defects induced by cleavage
This study shows the importance of PDK1, TOR and PKC signalling pathways to the basal tolerance of Cryptococcus neoformans towards fluconazole, the widely used drug for treatment of cryptococcosis. Mutations in genes integral to these pathway resulted in hypersensitivity to
