    BIOCELL, Vol.49, No.3, pp. 503-518, 2025, DOI:10.32604/biocell.2025.059286 - 31 March 2025

    Abstract Background: Nudix Hydrolase 21 (NUDT21) is crucial for the regulation of alternative polyadenylation, with its reduced expression frequently resulting in a shortened mRNA 3 untranslated region (UTR), thereby enhancing the protein levels of downstream genes. Although NUDT21 is widely recognized for its tumor-suppressive function in various cancers, its involvement in colorectal cancer (CRC) remains poorly understood. Methods: The expression of NUDT21 in CRC and adjacent normal tissues was analyzed through qPCR, Western blot, and immunohistochemistry (IHC). Additionally, we investigated the correlation between NUDT21 expression and patient prognosis. With Cell Counting Kit-8 assay and Transwell assay, we… More >

    How to make the end of a gene, the simple way

    KAREL H. M. VAN WELY*

    BIOCELL, Vol.46, No.6, pp. 1453-1457, 2022, DOI:10.32604/biocell.2022.018939 - 07 February 2022

    Abstract Transcription termination of nearly all protein-coding genes in mammals requires 3’ end processing by a multiprotein complex that will cleave and polyadenylate the messenger RNA precursor. Because a variety of enzyme complexes intervene, 3’ end processing was thought to be fundamentally complex and subject to a multitude of regulatory effects. The possibility to select just one out of several polyadenylation sites, in particular, has caused much questioning and speculation. What appear to be separate mechanisms however can be combined into a defined set of rules, allowing for a relatively simple interpretation of 3’ end processing. More >
