Robust designation of meiotic crossover sites by CDK-2 through phosphorylation of the MutS gamma complex

Crossover formation is essential for proper segregation of homologous chromosomes during meiosis. Here, we show that Caenorhabditis elegans cyclin-dependent kinase 2 (CDK-2) partners with cyclin-like protein COSA-1 to promote crossover formation by promoti ...

Identification of novel PCTAIRE-1/CDK16 substrates using a chemical genetic screen

Kei Sakamoto, Caterina Collodet, Maria Deak

PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK) 16), is a Ser/Thr kinase that has been implicated in many cellular processes, including cell cycle, spermatogenesis, neurite outgrowth, and vesicle trafficking. Most recently, it has been propo ...

Bacterial cell cycle dynamics: size regulation during exponential growth and role of polyphosphate during starvation response

Aster Louis K Vanhecke

Bacteria are the most diverse and abundant kingdom of life and have adapted to survive and thrive in habitats around the globe. When provided with ample nutrients they grow and divide at staggering rates, increasing their population exponentially. Upon nut ...

Physiological regulation of the CDK16/PCTAIRE-1 protein kinase and its proposed role in the brain

Saifeldin Nasser Mohamed Ibrahim Shehata

Cell signalling, mediated to a large extent by protein kinase phosphorylation, plays a vital role in regulation of cellular function. PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK)16), is a Ser/Thr kinase that has been implicated in many ce ...

Aurora A kinase regulates proper spindle positioning in C-elegans and in human cells

Pierre Gönczy, Coralie Busso, Sachin Kotak

Accurate spindle positioning is essential for error-free cell division. The one-cell Caenorhabditis elegans embryo has proven instrumental for dissecting mechanisms governing spindle positioning. Despite important progress, how the cortical forces that act ...

NuMA phosphorylation by CDK1 couples mitotic progression with cortical dynein function

Pierre Gönczy, Coralie Busso, Sachin Kotak

Spindle positioning and spindle elongation are critical for proper cell division. In human cells, an evolutionary conserved ternary complex (NuMA/LGN/Gαi) anchors dynein at the cortex during metaphase, thus ensuring correct spindle positioning. Whether thi ...

Conjugation of organoruthenium(II) 3-(1H-benzimidzol-2-yl)-pyrazolo[3,4-b]pyridines and indolo-[3,2-d]benzazepines to recombinant human serum albumin: a strategy to enhance cytotoxicity in cancer cells

Paul Joseph Dyson, Angela Casini, Fabio Edafe

Following our strategy of coupling cyclin-dependent kinase (Cdk) inhibitors with organometallic moieties to improve their physicochemical properties and bioavailability, five organoruthenium complexes (1c-5c) of the general formula [RuCl(eta(6)-arene)(L)]C ...

Targeting cap-dependent translation blocks converging survival signals by AKT and PIM kinases in lymphoma

Elisa Oricchio

New anticancer drugs that target oncogenic signaling molecules have greatly improved the treatment of certain cancers. However, resistance to targeted therapeutics is a major clinical problem and the redundancy of oncogenic signaling pathways provides back ...

Tracking and synchronization of the yeast cell cycle using dielectrophoretic opacity

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre, Ana Valero

Cell cycle synchronization is an important tool for the study of the cell division stages and signalling. It provides homogeneous cell cultures that are of importance to develop and improve processes such as protein synthesis and drug screening. The main a ...

Cyclin D1 Enhances the Response to Estrogen and Progesterone by Regulating Progesterone Receptor Expression

Cathrin Brisken

Estrogen and progesterone are the defining hormones of normal female development, and both play critical roles in breast carcinogenesis. Cyclin D1 is a breast cancer oncogene whose amplification is linked to poor prognosis in estrogen and progesterone rece ...

Two distinct mechanisms underlie progesterone-induced proliferation in the mammary gland

Cathrin Brisken, Ayyakkannu Ayyanan, Marian Caikovski

The mouse mammary gland develops postnatally under the control of female reproductive hormones. Estrogens and progesterone trigger morphogenesis by poorly understood mechanisms acting on a subset of mammary epithelial cells (MECs) that express their cognat ...

H2AX is required for cell cycle arrest via the p53/p21 pathway

Peter Martin Beard, Michail Fragkos

Phosphorylation of H2AX (gamma H2AX) is an early sign of DNA damage induced by replication stalling. However, the role of H2AX in the repair of this type of DNA damage is still unclear. In this study, we used an inactivated adeno-associated virus (AAV) to ...

Plants, MEN and SIN

Viesturs Simanis

In fission yeast, the onset of septation is signalled through the septum initiation network (SIN) signaling pathway. Similarly, in budding yeast the onset of budding is signalled through the mitotic exit network (MEN) pathway. We previously characterized i ...

The double life of UPF1 in RNA and DNA stability pathways

Joachim Lingner

The DNA and RNA helicase UPF1 is well known for its central role in Nonsense Mediated RNA Decay (NMD), which promotes degradation of mRNAs containing premature stop codons. However, we have recently demonstrated that human UPF1 is also essential for DNA re ...

The human RNA surveillance factor UPF1 is required for S phase progression and genome stability

Joachim Lingner

The eukaryotic nonsense-mediated mRNA decay (NMD) pathway degrades mRNAs carrying premature stop codons (PTC). In humans, NMD depends on the RNA- and DNA-dependent 5'-3' helicase UPF1 and six other gene products referred to as SMG1, UPF2, UPF3, EST1A/SMG6, ...

A role for the Cdc14-family phosphatase Flp1p at the end of the cell cycle in controlling the rapid degradation of the mitotic inducer Cdc25p in fission yeast

Viesturs Simanis

The Schizosaccaromyces pombe protein Flp1p belongs to a conserved family of serine-threonine-phosphatases. The founding member of this family, Saccharomyces cerevisiae Cdc14p, is required for inactivation of mitotic CDKs and reversal of CDK mediated phosph ...

Flp1, a fission yeast orthologue of the s. cerevisiae CDC14 gene, is not required for cyclin degradation or rum1p stabilisation at the end of mitosis

Viesturs Simanis

In Saccharomyces cerevisiae, the phosphoprotein phosphatase Cdc14p plays a central role in exit from mitosis, by promoting B-type cyclin degradation and allowing accumulation of the cyclin-dependent kinase inhibitor Sic1p. Cdc14p is sequestered in the nucl ...
