• Fast and safe: new reversibly switchable fluorescent proteins for live-cell nanoscopy science news VII.10

    Russian scientists together with colleagues from Sweden and the USA developed red fluorescent tags that are safe for nanoscopy in living cells. This work was funded by a grant from the Russian Science Foundation (RSF), and the results are published in Nature Methods journal.

  • Genetically encoded fluorescent pH probe for precise monitoring of cellular biochemistry science news V.3

    One of the directions of the Molecular Technologies Laboratory is the development of new tools for bioimaging and optogenetics. Yulia Ermakova, Vsevolod Belousov and other lab members, in an article in Chemical Communications, describe a new member of SypHer family of genetically encoded pH indicators, SypHer3s.

  • Spider venom will cure from paralysis science news IV.13

    Scientists from IBCh RAS together with foreign colleagues discovered that a toxin from the venom of the spider Heriaeus melloteei may serve as a hit in drug discovery for hypokalemic periodic paralysis type 2. The disease is caused by mutations in the gene encoding voltage-gated sodium channels NaV1.4, characteristic of skeletal muscles. As a result of the mutations, these channels conduct aberrant currents, the muscles are unable to respond to the signals of the nervous system, and weakness develops followed by paralysis. Until now, there is no reliable medication for all cases of this disease. The results of the work are published in the Proceedings of the National Academy of Sciences of the USA (PNAS).

  • The lecture by prof. Chandi C. Mandal Cancer biology basics. An intriguing link between cholesterol and tumorigenesis science news VIII.2 (This event is over)

    Thursday, 2 august, 15-00.Seminar room, bld. 34, stage 5.   Chandi C. Mandal, PhD Associate Professor and Head Department of Biochemistry School of Life Sciences Central University of Rajasthan Dr. Mandal’s research interests: Finding the underlying molecular mechanism for cholesterol-induced cancer growth and Metastasis Investigating the molecular mechanism involved in cancer microcalcification and its prevention strategy Investigating the target identification for cold-mediated tumorigenesis Study for preventing mutation in mutation prone zones in cancer genome Identification of bioactive secondary metabolites for prevention of cancer metastasis   Part 1. Cancer biology basics (15-00) Part 2. An intriguing link between cholesterol and tumorigenesis (15-40) Obesity, diabetes and hormonal imbalance have been linked with cancer incidence and/or mortality. Several findings have focused on high cholesterol as a cancer driving intrinsic factor. Although, this link has not yet been established well. This study aimed to find out whether elevation of cellular cholesterol promotes tumorigenesis. Our nationwide statistical analyses found an existence of positive correlation between cancer mortality rate and total average serum cholesterol of the population of a country. This positive relationship was also noticed in various anatomical site-specific cancers including thyroid, breast, ovary and others, except liver and cervical cancers. Moreover, tumor sample study found the higher expressions of cellular cholesterol regulatory genes (e.g. HMGCoR, LDLR) and elevated level of cholesterol in malignant breast cancer tissues as compared to benign tissues. Cell culture study documented that treatment of breast cancer cells with cholesterol increased cell proliferation and migration of breast cancer cells. Whereas, cholesterol depleting MBCD inhibited cell proliferation, EMT and stemness in breast cancer cells.
