This study shows TGF-beta signaling suppresses epithelial permeability in Drosophila ovaries by enhancing E-Cadherin adhesion, independent of actomyosin contractility.

The paper tracks exocytic vesicle movements in epithelial cells to show microtubule organisation controls apical secretion and reveals spatially organised ECM secretion.

The paper shows that Rho/Rok-dependent regulation of actomyosin contractility at tricellular junctions controls epithelial permeability in Drosophila by modulating vertex tension.

This study investigates the role of Src42A in E-cadherin dynamics during Drosophila axis elongation, showing its requirement for junction contraction and planar polarity.

The paper identifies Stac-positive extracellular vesicles derived from multivesicular bodies that mediate tracheal tube fusion in Drosophila embryos through the action of Arl3, Rab27, and Rab35.

The paper shows that transient opening of tricellular vertices in Drosophila follicle epithelium allows paracellular transport of yolk proteins during oogenesis, regulated by adhesion and actomyosin dynamics.

This study shows Smg5 is essential for NMD in Drosophila, participating in two decay mechanisms and compensating for Smg1's reduced role when Smg5 is compromised.
