Heme, a complex of iron and protoporphyrin IX, plays an essential role in numerous biological processes including oxygen transport, oxygen storage, and electron transfer. The role of heme as a prosthetic group in bacterial hemoprotein gas sensors, which utilize heme as a cofactor for the binding of diatomic gas molecules, has been well studied. Less well known is the role of protein sensors of heme. In this report, we characterize the heme binding properties of a phosphodiesterase, CdpA, from Vibrio cholerae. We demonstrate that the N-terminal domain of CdpA is a NosP domain capable of heme binding, which consequently inhibits the c-di-GMP hydrolysis activity of the C-terminal phosphodiesterase domain. Further evidence for CdpA as a heme responsive sensor is supported by a relatively fast rate of heme dissociation. This study provides insight into an emerging class of heme-responsive sensor proteins.The intracellular accumulation of α-synuclein (α-syn) amyloid fibrils is a hallmark of Parkinson's disease. Because lysosomes are responsible for degrading aggregated species, enhancing lysosomal function could alleviate the overburden of α-syn. Previously, we showed that cysteine cathepsins (Cts) is the main class of lysosomal proteases that degrade α-syn, and in particular, CtsL was found to be capable of digesting α-syn fibrils. Here, we report that CtsK is a more potent protease for degrading α-syn amyloids. Using peptide mapping by liquid chromatography with mass spectrometry, critical cleavage sites involved in destabilizing fibril structure are identified. CtsK is only able to devour the internal regions after the removal of both N- and C-termini, indicating their protective role of the amyloid core from proteolytic attack. Our results suggest that if overexpressed in lysosomes, CtsK has the potential to ameliorate α-syn pathology.The current gold standard for diagnosis of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) is through a liver biopsy, and there is an urgent need to develop non-invasive methods for early detection. We previously demonstrated metabolic remodeling in the mouse fatty liver, which is marked by increased hepatic expression and activities of phosphoglucose isomerase (PGI) and several other glycolytic enzymes. Since PGI is actively transported out of the cell, acting as a multifunctional cytokine referred to as autocrine motility factor (AMF), we explored the possibility that PGI secreted from the fatty liver may be targeted for early detection of the silent disease. We report here that mice with NASH exhibited significantly elevated serum PGI enzyme activities compared to normal control (P less then 0.005). We further confirmed the finding using serum/plasma samples (n = 73) collected from a cohort of NASH patients who were diagnosed according to Kleiner's criteria, showing a normal mean PGI of 19.5 ± 8.8 IU/L and patient mean PGI of 105.6 ± 79.9 IU/L (P less then 0.005). In addition, elevated blood PGI in NASH patients coincided with increased blood L-lactate. Cell culture experiments were then conducted to delineate the PGI-lactate axis, which revealed that treatment of HepG2 cells with recombinant PGI protein stimulated glycolysis and lactate output, suggesting that the disease-induced PGI likely contributed to the increased lactate in NASH patients. Taken together, the preclinical and clinical data validate secreted PGI as a useful biomarker of the fatty liver that can be easily screened at the point of care.
Diabetes is a hyperglycaemic disease treated by a set of allopathic drugs and natural biomolecules along with many variety of stem cell. We aim to investigate the role of these drugs in targeting common protein molecule in diabetes and its associated disease. We also aim to investigate the organ degeneration mechanistic pathway in diabetes.

We have generated diabetes using streptozotocin injection and treated them using bone marrow transplantation and curcumin administration. The organs were studied histopathologically and by immunofluorescence analysis while drugs were studied Pharmacogenomically.

Mice injected with streptozotocin have higher glucose and lower insulin, islet number/diameter, bone marrow cell number compared to control and bone marrow transplanted and curcumin administered mice. Histopathology staining demonstrates damaged morphology of pancreas, kidney, brain and cardiac muscle. selleck chemicals Further, upon comparison of all allopathic and ayurvedic drugs used for diabetes several protein targets have been identified by reverse pharmacophore analysis using PharmMapper. VEGF, CDK2, insulin receptor, HSp90, eNOS, Fructose1,6 bisphosphatase, neprilysin, AchE, MAPK are several common protein targets of anti-diabetic drugs.

This article demonstrates that VEGF and CDK2 are critical marker in organ damage in diabetes as well as organ regeneration.

However, the mechanisms underlying NSCLC tumorigenesis are incompletely understood. TAGLN, also named SM22, as a member of the calponin family, is highly expressed in many types of tumors. Nevertheless, its effects on NSCLC progression remain unclear. In this study, we found that TAGLN was over-expressed in tumor tissues of NSCLC patients and cell lines. Additionally, NSCLC patients with high expression showed worse overall survival rate. Then, gene silencing results indicated that TAGLN knockdown markedly inhibited proliferation and induced apoptosis in NSCLC cells, while rescue study exhibited opposite results. Moreover, suppressing TAGLN significantly reduced migration and invasion of NSCLC cells, and its over-expression promoted the migratory and invasive activities of NSCLC cells. The in vivo studies confirmed the oncogenic roles of TAGLN in NSCLC, along with clearly elevated metastasis. Notably, these effects were abrogated in mice with TAGLN deletion. Finally, we found that TAGLN knockdown could improve the sensitivity of NSCLC cells to sorafenib (SFB) and 5-FU treatment, further suppressing the proliferation, migration and invasion of NSCLC cells. Consistently, TAGLN deletion attenuated tumor xenografts growth and metastasis of NSCLC in mouse models by enhancing the anti-cancer effects of SFB and 5-FU. Altogether, these findings demonstrated that TAGLN functioned as an oncogene as well as a chemotherapeutic regulator during NSCLC development, which suggested a potential therapeutic strategy for NSCLC treatment mainly through repressing TAGLN expression.
