Haploinsufficiency networks identify targetable patterns of allelic deficiency in low mutation ovarian cancer.

Identification of specific oncogenic gene changes has enabled the modern generation of targeted cancer therapeutics. In high-grade serous ovarian cancer (OV), the bulk of genetic changes is not somatic point mutations, but rather somatic copy-number alterations (SCNAs). The impact of SCNAs on tumour biology remains poorly understood.

Integrin α4 Enhances Metastasis and May Be Associated with Poor Prognosis in MYCN-low Neuroblastoma.

High-risk neuroblastoma is associated with an overall survival rate of 30-50%. Neuroblastoma-expressed cell adhesion receptors of the integrin family impact cell adhesion, migration, proliferation and survival. Integrin α4 is essential for neural crest cell motility during development, is highly expressed on leukocytes, and is critical for transendothelial migration.

Caspase-8 isoform 6 promotes death effector filament formation independent of microtubules.

Caspase-8 can trigger cell death following prodomain-mediated recruitment to the 'death-inducing signaling complex.' The prodomain consists of two death effector domain (DED) motifs that undergo homotypic interactions within the cell. Aside from mediating recruitment of procaspase-8, the prodomains have also been implicated in regulating cell survival, proliferation, death, senescence, differentiation, and substrate attachment.
