Does chimeric transcript generated by cis-splicing of adjacent genes regulate prostate cancer cell proliferation?
With the absence of corresponding DNA rearrangement, chimeric fusion SLC45A3-ELK4 transcript in prostate cancer cells is generated by cis-splicing of adjacent genes/gene read-through instead of trans-splicing. SLC45A3-ELK4 controls prostate cancer cell proliferation, and the chimera level correlates with prostate cancer disease progression.
The target protein FSP1 identifies human fibroblasts and tubular epithelium undergoing EMT, and distinguishes them from the diaspora of alpha-SMA+ vascular smooth muscle cells. FSP1+ fibroblasts are critically related to the progression of IgAN; consequently, staining FSP1 in renal biopsy specimens provides a valuable histologic index of progression.
