News ArticlesFrom spatial proteomics to tissue validation: DHCR7 in early ovarian cancerA recent Molecular Systems Biology study used exploratory spatial proteomics to investigate early changes in high-grade serous ovarian cancer, including precursor lesions in the fallopian tube. In this interview by Gustav Ceder, Dr Fabian Coscia and Dr Mihnea-Paul Dragomir discuss how the team moved from spatial proteomics discovery to tissue-based validation using an Atlas Antibodies / Human Protein Atlas antibody against DHCR7...Read more RNF126 and the dedifferentiation of liver cancerAn article in PNAS describes how hypoxia and the elimination of peroxisomes drives HCC dedifferentiation, a hallmark of malignancy and a challenge for therapy. The E3 ubiquitin ligase RNF126 is identified as a hypoxia-inducible switch that determines peroxisomal fate and links the hypoxic microenvironment to loss of hepatocyte differentiation...Read more Multiplex tissue image of the month - BHLHA15 in salivary glandThe multiplex tissue image of this month showcases the spatial expression pattern of acinar cell-regulating basic helix-loop-helix family member a15 (gene: BHLHA15) in exocrine glandular structures of the salivary gland...Read more Mitochondria go where they are neededMitochondria are well known as the energy factories of human cells, but their roles extend well beyond ATP production, with multiple links to other cellular functions continuously being discovered. As can be seen in the subcellular resource of the HPA, the positioning of mitochondria within cells is variable, both between cell types and from cell-to-cell. This arrangement is not random, but rather regulated and highly dynamic. In fact, their proximity and direct interactions with other organelles can regulate cellular processes in these compartments...Read more Multiplex tissue image of the month - FOXJ1 and HMGN3 in fallopian tubeIn this edition of multiplex tissue image of the month, the expression pattern of ciliogenesis-activating transcription factor FOXJ1 is contrasted with chromatin-regulating protein HMGN3 in fallopian tube...Read more |
