Mitochondria play a central role in regulating cellular energy metabolism. However, the present understanding of mitochondria has changed from its unipotent functions to pluripotent and insists on understanding the role of mitochondria not only in regulating the life and death of cells, but in pathological conditions such as cancer. Unlike other cellular organelles, subtle alterations in mitochondrial organization may significantly influence the balance between metabolic networks and cellular behavior. Therefore, the delicate balance between the fusion and fission dynamics of mitochondrion can indicate cell fate. Here, we present mitochondrial chaperone TRAP1 influence on mitochondrial architecture and its correlation with tumor growth and metastasis. We show that TRAP1 overexpression (TRAP1 OE) promotes mitochondrial fission, whereas, TRAP1 knockdown (TRAP1 KD) promotes mitochondrial fusion. Interestingly, TRAP1 OE or KD had a negligible effect on mitochondrial integrity. However, TRAP1 OE cells exhibited enhanced proliferative potential, while TRAP1 KD cells showing increased doubling time. Further, TRAP1 dependent mitochondrial dynamic alterations appeared to be unique since mitochondrial localization of TRAP1 is a mandate for dynamic changes. The expression patterns of fusion and fission genes have failed to correlate with TRAP1 expression, indicating a possibility that the dynamic changes can be independent of these genes. In agreement with enhanced proliferative potential, TRAP1 OE cells also exhibited enhanced migration in vitro and tumor metastasis in vivo. Further, TRAP1 OE cells showed altered homing properties, which may challenge site-specific anticancer treatments. Our findings unravel the TRAP1 role in tumor metastasis, which is in addition to altered energy metabolism.The present study investigated the effect of culture extracts (CB08035-SCA and CB08035-SYP) from Marinobacter hydrocarbonoclasticus (strain CB08035) on cell viability and the potential protective effects attributed to molecular mechanisms underlying antioxidant response to survive oxidative stress injuries. Caco-2 cells were submitted to oxidative stress by treatment with tert-butyl hydroperoxide (t-BOOH). Both extracts prevented cell damage and enhanced activity of antioxidant defenses (NQO1 and GST activities and GSH levels) reduced by treatment with t-BOOH. Increased ROS and caspase 3/7 activity induced by t-BOOH were dose-dependently prevented when cells were treated with the extracts. CB08035-SCA caused up-regulation of Nrf2, AKT1 and Bcl-2 gene expressions. Selleckchem NRD167 Moreover, CB08035-SCA and CB08035-SYP treatments reduced significantly Bax, BNIP3, APAF1, ERK1, JNK1, MAPK1, NFκB1, TNFα, IL-6, IL-1β and HO-1 gene expressions of apoptosis, proinflammation and oxidative stress induced by t-BOOH. CB08035-SCA and CB08035-SYP CPE extracts confer a significant protection against oxidative insults to cells. Our results show that culture extracts CB08035-SCA and CB08035-SYP from M. hydrocarbonoclasticus (strain CB08035) appeared to have antioxidant potential, based on their ability to protect antioxidant enzymes and mRNA gene expressions linked to apoptosis/oxidative pathways. These results suggest that culture extracts CB08035-SCA and CB08035-SYP can be a potential ingredient in the pharmaceutical and cosmeceutical industries.Natural products, being richly endowed with curative powers, have become spotlight for biomedical and pharmaceutical research to develop novel therapeutics during recent years. Ginkgetin (GK), a natural non-toxic biflavone, has been shown to exhibit anti-cancer, anti-inflammatory, anti-microbial, anti-adipogenic, and neuroprotective activities. GK combats cancer progression by arresting cell cycle, inducing apoptosis, stimulating autophagy, and targeting many deregulated signaling pathways such as JAK/STAT and MAPKs. GKhalts inflammation mediators like interleukins, iNOS, COX-2, PGE2, NF-κB, and acts as an inhibitor of PLA2. GK shows strong neuroprotection against oxidative stress-promoted cell death, inhibits cerebral micro-hemorrhage, decreases neurologic deficits, and halts apoptosis of neurons. GK also acts as anti-fungal, anti-viral, anti-bacterial, leishmanicidal and anti-plasmodial agent. GK shows substantial preventive or therapeutic effects in in vivo models of many diseases including atherosclerosis, cancer, neurodegenerative, hepatic, influenza, and inflammatory diseases. Based on various computational, in vitro and in vivo evidences, this article demonstrates the potential of ginkgetin for development of therapeutics against various diseases. Although GK has been systematically studied from pharmacological point of view, a vast field of pharmacokinetics, pre-clinical and clinical studies is still open for the researchers to fully validate its potential for the treatment of various diseases.Ulcerative colitis (UC) is a chronic inflammatory disease with increasing incidence and prevalence worldwide. Currently used treatments of UC are unsatisfactory, while natural bioactive compounds are considered to be emerging therapeutic agents. Luteolin (Lut) is a natural compound with beneficial effects in a variety of diseases, however, its effect in UC has been poorly studied. In this study we investigated the effect of Lut in posttreatment and cotreatment of dextran sulfate sodium (DSS)-induced experimental colitis in mice. In addition, the role of extracellular signal-regulated kinases 1/2 (ERK1/2) in the mechanism of action of Lut in experimental colitis was investigated using the ERK inhibitor PD0325901. Lut attenuated symptoms of DSS-induced colitis in mice, ameliorated colon tissue damage and reduced inflammation, apoptosis and autophagy. The effect was more pronounced if Lut was administered simultaneously with DSS. The administration of ERK inhibitor exacerbated DSS-induced colitis symptoms and prevented the protective effects of Lut. The results provide new mechanistic details underlying the anti-inflammatory, anti-apoptotic and anti-autophagic effects of Lut through the activation of the ERK signaling pathway. This suggested that Lut can be used as a novel therapeutic candidate in the treatment of UC or could be used as a supplement to existing therapy.
