However, in the OMCD, strong AQP3 expression was observed at the basolateral plasma membrane
of ND compared with the HFD (Figs.
This might be achieved by either changing their transport activity rates or, alternatively, their abundance in the basolateral plasma membrane
For the osmoregulatory organs, AQP3 is constitutively located in the basolateral plasma membrane
of tight-junctioned epithelial cells.
AQP3 and AQP4 are present in the basolateral plasma membrane
of collecting duct principal cells and represent exit pathways for water reabsorbed apically via AQP2 .
Basolateral plasma membrane vesicles were obtained as described by del Castillo et al (16).
Each experimental data (n) corresponds to results obtained from different basolateral plasma membrane preparations.
To verify the presence of both [Na.sup.+]-ATPase and [Na.sup.+]/[K.sup.+]-ATPase in basolateral plasma membrane the ATPase activity was measured (Table I).
However, in the OMCD, moderate AQP3 expression was observed at the basolateral plasma membrane of camel compared with the control (Figs.
To investigate whether AQP4 expression was similar to the AQP3 at the basolateral plasma membrane of the IMCD and the OMCD of camel, respectively.
The basolateral plasma membrane was relatively straight nearest the lumen, but closer to the basal lamina it was interdigitated with itself and adjacent cells (Fig.
Regions of the basolateral plasma membrane that contacted the basement membrane did not exhibit CAH.
Freeze fracture replicas showed that the only distinguishing intramembranous particles were in the basolateral plasma membrane. The size and distribution of the particles forming these clusters was comparable to those forming gap junctions in mammalian cells.
