Fibroblast lipid cues shape squamous cell carcinoma invasion
—
in Biochemistry, Genetics and Molecular Biology
What the study found Fibroblasts from different tissue sites provide site-specific lipid cues that influence squamous cell carcinoma (SCC) proliferation and invasion. Oral and lung fibroblasts transfer different lipids to SCC cells, while dermal fibroblasts are described as lipid poor. Why the authors say this matters The authors conclude that these fibroblast lipid cues help…
Model captures border cell cluster migration features in Drosophila
—
in Biochemistry, Genetics and Molecular Biology
What the study found A biophysically informed phase-field model reproduced key features of border cell cluster migration in the Drosophila melanogaster egg chamber. The model included a contact-mediated propulsion mechanism called Tangential Interface Migration (TIM) and captured motion shaped by tissue geometry and chemical cues. Why the authors say this matters The authors conclude that…
PAF15-PCNA exhaustion limits strand-specific DNA replication control

in Biochemistry, Genetics and Molecular Biology
Study reveals PAF15-PCNA interaction as a strand-specific constraint that couples lagging-strand synthesis capacity to global DNA replication control through dosage-sensitive mechanism.
