Adherens junctions limit the extent of the septate junctions in Drosophila midgut enterocytes but are not required for apical-basal polarity

C. A. Carvalho, M. A. Tame, D. St Johnston

The paper investigates the role of E-cadherin adhesion complexes in Drosophila midgut epithelial polarity, finding they limit septate junction extent but are not required for apical-basal polarity.

Tracking exocytic vesicle movements reveals the spatial control of secretion in epithelial cells.

J. H. Richens, M. Dmitrieva, H. L. Zenner, N. Muschalik, R. Butler, J. Glashauser, C. Camelo, S. Luschnig, S. Munro, J. Rittscher, D. St Johnston

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

User-friendly Oblique Plane Microscopy on a fully functional commercially available microscope base

G. Sirinakis, E. S. Allgeyer, D. Nashchekin, D. St Johnston

This paper presents an oblique plane microscope compatible with a commercial base, showing minimal impact on resolution and data fidelity despite objective lens displacement.

The Shot CH1 domain recognises a distinct form of F-actin during Drosophila oocyte determination

D. Nashchekin, I. Squires, A. Prokop, D. St Johnston

The study identifies the Shot CH1 domain's specific recognition of fusomal F-actin in Drosophila oocyte determination.

De novo apical domain formation inside the Drosophila adult midgut epithelium

J. Chen, D. St Johnston

The paper describes how enteroblasts in Drosophila midgut form an apical domain by creating an apical membrane initiation site and integrating into the epithelium.

A method for single molecule localization microscopy of tissues reveals nonrandom distribution of nuclear pores in Drosophila

J. Cheng, E. S. Allgeyer, J. H. Richens, E. Dzafic, A. Palandri, B. Lewkow, G. Sirinakis, D. St Johnston

This paper develops a line scanning SMLM system for tissue imaging, revealing nonrandom nuclear pore distribution in Drosophila tissues, contrasting with cultured cells.

RhoGAP19D inhibits Cdc42 laterally to control epithelial cell shape and prevent invasion

W. Fic, R. Bastock, F. Raimondi, E. Los, Y. Inoue, J. Gallop, R. B. Russell, D. St Johnston

The paper identifies RhoGAP19D as a Cdc42 GTPase Activating Protein that restricts Cdc42 activity to the apical domain, preventing epithelial invasion.

An alternative mode of epithelial polarity in the Drosophila midgut

J. Chen, A.-C. Sayadian, N. Lowe, H. Lovegrove, D. St Johnston

The paper shows that Drosophila midgut epithelia polarize without canonical polarity factors, using integrin adhesion instead, suggesting conserved diversity in polarity mechanisms across species.

Localised Dynactin Protects Growing Microtubules To Deliver Oskar mRNA To The Posterior Cortex Of The Drosophila Oocyte

R. Nieuwburg, D. Nashchekin, M. Jakobs, A. Carter, P. Khuc Trong, R. E. Goldstein, D. St Johnston

The paper shows that Dynactin protects microtubule growth to deliver oskar mRNA to the posterior cortex of the Drosophila oocyte.
