Role for non-proteolytic control of M-phase-promoting factor activity at M-phase exit.

open access: yesPLoS ONE, 2007
M-phase Promoting Factor (MPF; the cyclin B-cdk 1 complex) is activated at M-phase onset by removal of inhibitory phosphorylation of cdk1 at thr-14 and tyr-15. At M-phase exit, MPF is destroyed by ubiquitin-dependent cyclin proteolysis.

Cyclin B3 is a dominant fast-acting cyclin that drives rapid early embryonic mitoses. [PDF]

open access: yes
Mitosis in early embryos often proceeds at a rapid pace, but how this pace is achieved is not understood. Here, we show that cyclin B3 is the dominant driver of rapid embryonic mitoses in the C. elegans embryo.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

M2I-1 disrupts the in vivo interaction between CDC20 and MAD2 and increases the sensitivities of cancer cell lines to anti-mitotic drugs via MCL-1s [PDF]

open access: yes, 2019
Background Drugs such as taxanes, epothilones, and vinca alkaloids are widely used in the treatment of breast, ovarian, and lung cancers but come with major side effects such as neuropathy and loss of neutrophils and as single agents have a lack of ...

Effect of Natural Polyphenols on Breast Cancer Chemoprevention and Treatment

open access: yesMolecular Nutrition &Food Research, EarlyView.
Effect of Natural Polyphenols on Breast Cancer proliferation and progression. ABSTRACT Breast cancer is the most common type of malignancy among women worldwide. Significant achievements have been made in diagnostic tools and cancer treatments in the past decade; however, the complexity and heterogeneity of certain breast cancer subtypes often lead to ...

Immortal, non‐tumourigenic mouse mammary outgrowths express high levels of cyclin B1 and activation of cyclin B1/cdc2 kinase

open access: yesCell Proliferation, 1996
Abstract. Neoplastic transformation of mouse mammary epithelial cells is the result of several identifiable phenotypic changes which presumably require sequential genetic alterations. In our model system, mammary cells progress from a mortal state (virgin duct) to several morphologically distinct intermediate states.

PD‐L1 Expression is Mediated by microRNA Processing, Wnt/β‐Catenin Signaling, and Chemotherapy in Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Inhibition of immune checkpoint proteins is effective in adult cancers but has shown limited efficacy in pediatric cancers. While factors regulating expression of immune checkpoint proteins such as PD‐L1 are well documented in adult cancers, their regulation is poorly understood in pediatric cancers.

Sodium selenite alters microtubule assembly and induces apoptosis in vitro and in vivo

open access: yesJournal of Hematology & Oncology, 2013
Background Previous studies demonstrated that selenite induced cancer-cell apoptosis through multiple mechanisms; however, effects of selenite on microtubules in leukemic cells have not been demonstrated.

Exosome‐Based Theranostic for Gastrointestinal Cancer: Advances in Biomarker Discovery and Therapeutic Engineering

open access: yesSmall Methods, EarlyView.
This review explores the dual roles of exosomes in gastrointestinal (GI) cancers as diagnostic biomarkers and therapeutic agents. It highlights advancements in exosomal miRNAs, lncRNAs, circRNAs, and proteins for cancer detection and prognosis. The study also examines engineering strategies for exosome‐based drug delivery systems, their potential to ...

MicroRNA-125b controls growth of ovarian granulosa cells in polycystic ovarian syndrome by modulating cyclin B1 expression

open access: yesArchives of Medical Science, 2019
Introduction There is a lot of evidence that suggests that microRNAs (miRs) play an imperative role in the pathogenesis of polycystic ovary syndrome (PCOS). This study was designed to decipher the role of miR-125b in PCOS pathogenesis.
