Cover: Green sea turtles (Chelonia mydas) are ectothermic marine animals and have well-adjusted physiological functions for prolonged dives. However, little is known about their heart rate and cardiac response to exercise during submergence. A study by Okuyama and colleagues used animal-borne ECG recorder and accelerometer to simultaneously record their heart rate and activity level during submergence. The results demonstrated that the 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.

RESEARCH ARTICLES
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.
Hormones as adaptive control systems in juvenile fish
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.
Loss of Crb2b-lf leads to anterior segment defects in old zebrafish
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.
Greb1 is required for axial elongation and segmentation in vertebrate embryos
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.
FAM172A inhibits EMT in pancreatic cancer via ERK-MAPK signaling
Summary: FAM172A inhibits EMT in pancreatic cancer via specifically regulating ERK-MAPK signaling.
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.

The remarkable cellular diversity of the African turquoise killifish telencephalon

African turquoise killifish have a remarkably short natural lifespan and their central nervous system has human-like ageing. Caroline Zandecki and colleagues reveal the cellular diversity during the explosive growth of the telencephalon.
Propose a new Workshop for 2027

We are currently seeking proposals for Workshops to be held in 2027. As one of the scientific organisers of a The Company of Biologists Workshop, your involvement will be focused on interdisciplinary, cutting-edge science and promoting new partnerships and collaborations. We focus on the logistics. Are you thinking about proposing a topic for one of our Workshops? Apply by Friday 30 May 2025.
