News ArticlesExploring CLOCK: Our Inner TimekeeperOur cells contain tiny molecular clocks that control a multitude of physiological and behavioral processes according to the circadian rhythm. Governed by a central clock, residing in the suprachiasmic nucleus of the brain, peripheral clocks are present in almost all tissues and organs (Hastings et al., 2003). They are, though able to persist in the absence of environmental cues, driven by the 24-hour patterns of light and temperature produced by the earth´s rotation, and periodically regulate functions such as body temperature, blood pressure, circulating hormones and metabolism (Mazzoccoli et al., 2012)...Read more Young researcher awarded large grant for FTD researchThe postdoc Emma Gerrits in Jan Mulders HPA related research group at KI has recently, as the youngest person ever, received a 1.2 MSEK grant from Alzheimerfonden for research on the development of Frontotemporal dementia (FTD)...Read more Altered plasma protein profiles in genetic FTDIn a study published in Molecular Neurodegeneration an international group of scientists including researchers from KTH have used a multiplex plasma profiling assay and a well-described genetic frontotemporal dementia (FTD) cohort collected within the GENFI study to explore potential plasma biomarkers that could reflect the pathology of this disease...Read more HSP60 - From Stress to SuccessProper three-dimensional structure of proteins is paramount to their function, and misfolded proteins not only lead to loss of that function but to aggregates that can disrupt cellular processes. In ideal conditions, proteins fold spontaneously into their native three-dimensional structures, driven by their amino acid sequence (Ellis, 1999). However, in the crowded and stressed environment of the cell, assistance is often required to avoid misfolding and aggregation. This week we highlight heat shock protein 60 (HSP60), pictured here in the mitochondria of U2OS cells. As a member of the class 1 chaperonin family, HSP60 assists in the folding of newly translated, imported, or denatured proteins in the mitochondrial matrix, particularly under conditions of stress such as high temperatures or UV light ( Hartl, 1996)...Read more A multi-omics strategy to discover and validate missing proteins in the ovaryIn a publication in Journal of Proteome Research transcriptomics and spatial proteomics were used to investigate and validate the expression of so-called missing proteins in the human ovary...Read more |
