Intertwined Functions of Separase and Caspase in Cell Division and Programmed Cell Death. [PDF]

open access: yes, 2020
Timely sister chromatid separation, promoted by separase, is essential for faithful chromosome segregation. Separase is a member of the CD clan of cysteine proteases, which also includes the pro-apoptotic enzymes known as caspases.

On the origin of trisomy 21 Down syndrome [PDF]

open access: yes, 2008
Background: Down syndrome, characterized by an extra chromosome 21 is the most common genetic cause for congenital malformations and learning disability.

Bacterial Chromosome Organization and Segregation [PDF]

open access: yesAnnual Review of Cell and Developmental Biology, 2015
If fully stretched out, a typical bacterial chromosome would be nearly 1 mm long, approximately 1,000 times the length of a cell. Not only must cells massively compact their genetic material, but they must also organize their DNA in a manner that is compatible with a range of cellular processes, including DNA replication, DNA repair, homologous ...

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier

open access: yesAdvanced Science, EarlyView.
SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

In Vivo Imaging of the Segregation of the 2 Chromosomes and the Cell Division Proteins of Rhodobacter sphaeroides Reveals an Unexpected Role for MipZ

open access: yesmBio, 2019
Coordinating chromosome duplication and segregation with cell division is clearly critical for bacterial species with one chromosome. The precise choreography required is even more complex in species with more than one chromosome.

Chromosome Segregation: Monopolin Goes Spindle [PDF]

open access: yesCurrent Biology, 2009
At anaphase onset the mitotic spindle undergoes dramatic changes in order to segregate sister chromatids. Surprisingly, the monopolin complex, best known for its role at kinetochores in meiosis, is now shown to localize to, and stabilize, the mitotic anaphase spindle.

Depletion of Sorcs3 Activates Totipotency in Mouse Embryonic Stem Cells by Modulating Key Signaling Pathways

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]

open access: yes, 2019
Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Chromosome Segregation: Reconstituting the Kinetochore [PDF]

open access: yesCurrent Biology, 2016
Faithful chromosome segregation is accomplished by attachment of chromosomes to spindle microtubules using the kinetochore. In a major step forward in understanding the functional and structural complexity of kinetochores, a 21-subunit human centromere - kinetochore complex has been reconstituted entirely from purified components, recreating the ...

A Novel FGFR3‐Targeting Antibody‐Drug Conjugate Induces Tumor Cell Apoptosis through the cGAS–STING Pathway in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
LZU‐WZLYCS01 is a novel FGFR3‐targeting ADC for bladder cancer with 7‐ethyl‐9‐fluorocamptothecin (A2) as its cytotoxic payload. LZU‐WZLYCS01 intracellularly releases A2, which targets MAD2L1 to activate the cGAS‐STING pathway and induce tumor cell apoptosis.
