TL;DR: increasing matrix stiffness promotes proliferation and chemotherapeutic resistance, whereas a soft environment induces reversible cellular dormancy and stem cell characteristics in HCC, which has implications for both the treatment of primary HCC and the prevention of tumor outgrowth from disseminated tumor cells.

TL;DR: Targeted disruption of Chk1 in mice showed that ChK1(-/-) embryos exhibit gross morphologic abnormalities in nuclei as early as the blastocyst stage, which may indicate that Chk 1 is indispensable for cell proliferation and survival through maintaining the G(2) checkpoint in mammals.
Abstract: The recent discovery of checkpoint kinases has suggested the conservation of checkpoint mechanisms between yeast and mammals. In yeast, the protein kinase Chk1 is thought to mediate signaling associated with the DNA damage checkpoint of the cell cycle. However, the function of Chk1 in mammals has remained unknown. Targeted disruption of Chk1 in mice showed that Chk1(-/-) embryos exhibit gross morphologic abnormalities in nuclei as early as the blastocyst stage. In culture, Chk1(-/-) blastocysts showed a severe defect in outgrowth of the inner cell mass and died of apoptosis. DNA replication block and DNA damage failed to arrest the cell cycle before initiation of mitosis in Chk1(-/-) embryos. These results may indicate that Chk1 is indispensable for cell proliferation and survival through maintaining the G(2) checkpoint in mammals.

TL;DR: Perturbations in each level of the IGF axis have been implicated in cancer formation and progression in various cell types and are believed to occur through IGFBP‐3‐specific cell surface association proteins or receptors and involves nuclear translocation.
Abstract: Interest in the role of the insulin-like growth factor (IGF) axis in growth control and carcinogenesis has recently been increased by the finding of elevated serum insulin-like growth factor I (IGF-I) levels in association with three of the most prevalent cancers in the United States: prostate cancer, colorectal cancer, and lung cancer. IGFs serve as endocrine, autocrine, and paracrine stimulators of mitogenesis, survival, and cellular transformation. These actions are mediated through the type 1 IGF-receptor (IGF-1R), a tyrosine kinase that resembles the insulin receptor. The availability of free IGF for interaction with the IGF-1R is modulated by the insulin-like growth factor-binding proteins (IGFBPs). IGFBPs, especially IGFBP-3, also have IGF-independent effects on cell growth. IGF-independent growth inhibition by IGFBP-3 is believed to occur through IGFBP-3-specific cell surface association proteins or receptors and involves nuclear translocation. IGFBP-3-mediated apoptosis is controlled by numerous cell cycle regulators in both normal and disease processes. IGFBP activity is also regulated by IGFBP proteases, which affect the relative affinities of IGFBPs, IGFs and IGF-1R. Perturbations in each level of the IGF axis have been implicated in cancer formation and progression in various cell types.

TL;DR: In this article, protein-free cell culture media supplements are described consisting of synergistic combinations of medium components, which when added to cell culture medium, either serum supplemented or serum-free, enhance cell growth, culture longevity and product expression.
