Tumour Antigen‐Specific Antibody Signatures as Diagnostic Biomarkers for Melanoma

International Journal of Cancer, EarlyView.
ABSTRACT Early detection of melanoma remains challenging, and minimally invasive diagnostic tools are needed to complement imaging and histopathology. Circulating tumour antigen‐specific antibodies (Abs) are promising biomarkers, but their diagnostic value across melanoma stages is not fully established.

Centrosome amplification primes ovarian cancer cells for apoptosis and potentiates the response to chemotherapy.

PLoS Biology
Centrosome amplification is a feature of cancer cells associated with chromosome instability and invasiveness. Enhancing chromosome instability and subsequent cancer cell death via centrosome unclustering and multipolar divisions is an aimed-for ...

Catalytic growth in a shared enzyme pool ensures robust control of centrosome size

eLife
Accurate regulation of centrosome size is essential for ensuring error-free cell division, and dysregulation of centrosome size has been linked to various pathologies, including developmental defects and cancer.

Excessive centrosome abnormalities without ongoing numerical chromosome instability in a Burkitt's lymphoma

Molecular Cancer, 2003
Numerical and structural centrosome abnormalities are detected in various human malignancies and have been implicated in the formation of multipolar mitoses, chromosome missegregation, and chromosomal instability.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal 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

CCDC102B functions in centrosome linker assembly and centrosome cohesion [PDF]

Journal of Cell Science, 2018
ABSTRACT The proteinaceous centrosome linker is an important structure that allows the centrosome to function as a single microtubule-organizing center (MTOC) in interphase cells. However, the assembly mechanism of the centrosome linker components remains largely unknown.

Basal body stability and ciliogenesis requires the conserved component Poc1 [PDF]

, 2009
Centrioles are the foundation for centrosome and cilia formation. The biogenesis of centrioles is initiated by an assembly mechanism that first synthesizes the ninefold symmetrical cartwheel and subsequently leads to a stable cylindrical microtubule ...

KAT8‐Low Osteosarcoma Suppresses Cisplatin Sensitivity via H4K16ac‐Mediated Cell Apoptosis

Med Research, EarlyView.
The scientific significance of this study is highlighted below: (1) Data mining and clinical discovery: These findings establish a direct clinical link between the KAT8–H4K16ac axis and chemotherapy response in osteosarcoma. (2) Multi‐omics and machine‐learning integration: We integrated proteomics and CUT&Tag multi‐omics to elucidate how chromatin ...

Sequential activities of Dynein, Mud and Asp in centrosome-spindle coupling maintain centrosome number upon mitosis

, 2017
Centrosomes nucleate microtubules and are tightly coupled to the bipolar spindle to ensure genome integrity, cell division orientation and centrosome segregation.

Cep164, a novel centriole appendage protein required for primary cilium formation [PDF]

, 2007
Primary cilia (PC) function as microtubule-based sensory antennae projecting from the surface of many eukaryotic cells. They play important roles in mechano- and chemosensory perception and their dysfunction is implicated in developmental disorders and ...
