The JNK phosphatase puckered, whose expression can be reported via a lacZ enhancer trap, is expressed in very low levels in uninjured neurons; however, nerve crush induces a dramatic increase in puc-l...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria but not in germaria with UAS-boi[RNAi] expression (CIL#13742). Germ cells are identified using anti-Vasa (blue). Imag...

The unique-6 (U6) motif of the MAGUK protein, ZO-1, inhibits tight junction localization of GFP fusion proteins containing the SH3-GUK module. Stable MDCK II cell lines expressing GFP fusion proteins ...

Liver of a rat exposed to chemical carcinogens. Serial sections of the liver imaged by laser scanning confocal microscopy. F-actin (red) is in bile canaliculi at junctions of the hepatocytes, which ...

The JNK phosphatase puckered, whose expression can be reported via a lacZ enhancer trap, is expressed in very low levels in uninjured neurons; however, nerve crush induces a dramatic increase in puc-l...

Immunohistochemistry of neuron-specific β-III-tubulin (red) shows the delicate dendrites of Purkinje cells in the cerebellum. Cell nuclei are revealed with DAPI staining (blue). Scale bar, 100 µm.

Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...

The unique-5 (U5) and unique-6 (U6) motifs of the MAGUK protein, ZO-1 are required for localization of ZO-1 to the apical tight junction. Cell lines expressing the myc-tagged transgenes ZO1-FL (A and ...

Patched (Ptc, green) is expressed in most cells of the Drosophila wild-type germarium including follicle stem cells. Hedgehog (Hh, red) accumulates on the surface of the apical cells. Germ cells are i...

Smoothened (Smo; green), a downstream effector of Hedgehog (Hh), is expressed in most cells of the wild-type Drosophila germarium including follicle stem cells, but is excluded from Boi- and Hh-expres...
