Tubulin-binding cofactor E-like (TBCEL), the protein product of the mulet gene, is required in the germline for the regulation of inter-flagellar microtubule dynamics during spermatid individualization
Summary: The leading cause of human male infertility is a failure to resolve spermatids from a germline syncytium during spermatid individualization. Here we characterize a mutation that disrupts this process.
Heart rate and cardiac response to exercise during voluntary dives in captive sea turtles (Cheloniidae)
Summary: Green turtles showed immediate cardiac response to exercise during submergence, presumably because they store oxygen primarily in the lungs and need blood circulation to meet the metabolic demand.
TRBP–Dicer interaction may enhance HIV-1 TAR RNA translation via TAR RNA processing, repressing host-cell apoptosis
Summary: HIV-1 RNA translation may be enhanced through TAR RNA processing by TRBP in collaboration with Dicer, repressing host–cell apoptosis.
Whole-genome fingerprint of the DNA methylome during chemically induced differentiation of the human AML cell line HL-60/S4
Summary: Epigenomics play a role in cell identity and differentiation. We present the DNA methylation landscape of leukemic cells during in vitro differentiation, adding another omics layer to better understand differentiation mechanisms.
Summary: We combine physiological, environmental and evolutionary aspects of fish growth in a state-dependent model where the optimal regulation of growth and survival is achieved through hormonal regulation of behaviour.
Summary: Loss of the apico-basal polarity regulator Crb2b-lf does not affect retinal development but leads to ocular anterior segment defects in old zebrafish.
Summary: The Greb1 transcriptional cofactor is expressed in the vertebrate tailbud and required for axial extension and segmentation of developing vertebrate embryos.
The absence of SOX2 in the anterior foregut alters the esophagus into trachea and bronchi in both epithelial and mesenchymal components
Summary: In response to the change in the epithelial characteristics from esophagus to trachea/bronchus that happens when SOX2 is inactivated, surrounding mesenchymal tissues also change their characteristics accordingly at all axial levels.
Polyphyllin II inhibits liver cancer cell proliferation, migration and invasion through downregulated cofilin activity and the AKT/NF-κB pathway
Summary: An important steroidal saponin extracted from Rhizoma Paris, Polyphyllin II suppressed cell viability and induced cell apoptosis in liver cancer cells. Low doses of Polyphyllin II also inhibited liver cancer cell migration and invasion.
Mechanical and molecular parameters that influence the tendon differentiation potential of C3H10T1/2 cells in 2D- and 3D-culture systems
Summary: Our results provide a better understanding of the culture conditions upon which we could act to trigger tendon cell differentiation from undifferentiated stem cells.
