Genetic Normalization of Differentiating Aneuploid Human Embryos [PDF]

, 2011
Early embryogenesis involves a series of dynamic processes, many of which are currently not well described or understood. Aneuploidy and aneuploid mosaicism, a mixture of aneuploid and euploid cells within one embryo, in early embryonic development are ...

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Targeting Cleavage of C-Terminal Fragment of Cytoskeletal Filamin A in Cancers

Cells
Human cancers express altered levels of actin-binding cytoskeletal filamin A (FLNA) protein. FLNA in mammals consists of an actin-binding domain at its N-terminus that is followed by 24 immunoglobulin-like repeat modules interrupted by two hinge regions ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Evidence for prelocalization of cytoplasmic factors affecting gene activation in early embryogenesis [PDF]

, 1965
Differentiation begins early in embryogenesis as different genes become active in different cells. Within the closed system of the early embryo, equal genomes thus direct the creation of diverse cell types.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Enteroviral 3C protease cleaves N4BP1 to impair the host inflammatory response

Journal of Virology
Enteroviral 3C protease (3Cpro) is an essential enzyme for viral replication and is responsible for combating the host anti-viral immune response by targeting cellular proteins for cleavage.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Characterization of full-length and cytoplasmic tail-truncated envelope glycoproteins incorporated into human immunodeficiency virus (HIV-1) virions and virus-like particles

Journal of Virology
During transport to the surface of infected cells, the human immunodeficiency virus (HIV-1) envelope glycoprotein (Env) trimer is cleaved to produce the mature functional Env trimer [(gp120/gp41)3].
