    Compensatory induction of MYC expression by sustained CDK9 inhibition via a BRD4-dependent mechanism

    Huasong Lu et al.
    A new potent and selective CDK9 inhibitor induces the expression of the proto-oncogene MYC via a mechanism that depends on the bromodomain protein BRD4.

    Targeting MYC dependency in ovarian cancer through inhibition of CDK7 and CDK12/13

    Mei Zeng et al.
    A multi-transcriptional CDKs inhibitor suppresses MYC and induces regression of ovarian tumors, indicating that targeting CDK7, 12, 13 with THZ1 may be an effective approach for treating MYC-dependent malignancies.

    The CUL5 ubiquitin ligase complex mediates resistance to CDK9 and MCL1 inhibitors in lung cancer cells

    Shaheen Kabir et al.
    Targeting the CRL5 ubiquitin ligase complex in combination with CDK9 or MCL1 inhibition could combat innate and acquired resistance of cancer cells to MCL1-targeting therapeutics.

    Assessing the mechanism and therapeutic potential of modulators of the human Mediator complex-associated protein kinases

    Paul A Clarke et al.
    Detailed molecular profiling investigations alongside antitumor testing and tolerability studies in animals suggest caution when considering the clinical development of inhibitors of CDK8 and CDK19, since a clear therapeutic window could not be demonstrated with two structurally distinct, potent and selective prototype drugs.

    CDK9-dependent RNA polymerase II pausing controls transcription initiation

    Saskia Gressel et al.
    CDK9 inhibition in human cells uncovers that Pol II pause duration regulates the frequency of productive transcription initiation.

    The aryl hydrocarbon receptor and interferon gamma generate antiviral states via transcriptional repression

    Tonya Kueck et al.
    Distinct antiviral signaling pathways, triggered by the aryl hydrocarbon receptor and Interferon-gamma, converge on CDK/cyclin repression, causing inhibition of viral DNA synthesis.

    Reliable cell cycle commitment in budding yeast is ensured by signal integration

    Xili Liu et al.
    The decision to commit to cell division-the Start transition-in budding yeast is governed by time integration of G1 cyclin-CDK activity by the transcription factor Whi5.

    Cell cycle entry triggers a switch between two modes of Cdc42 activation during yeast polarization

    Kristen Witte et al.
    Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.

    Fcp1 phosphatase controls Greatwall kinase to promote PP2A-B55 activation and mitotic progression

    Rosa Della Monica et al.
    The phosphatase Fcp1 inactivates Greatwall kinase at the end of mitosis.

    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky et al.
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.
