Evolution of root apical meristem structures in vascular plants: plasmodesmatal networks.

The apical meristem generates indeterminate apical growth of the stem and root of vascular plants. Our previous examination showed that shoot apical meristems (SAMs) can be classified into two types based on plasmodesmatal networks (PNs), which are important elements in symplasmic signaling pathways within the apical meristem. Here, we examined the PNs of root apical meristems (RAMs) in comparison with those of SAMs.

Rab17 Regulates apical delivery of hepatic transcytotic vesicles.

A major focus for our laboratory is identifying the molecules and mechanisms that regulate basolateral-to-apical transcytosis in polarized hepatocytes. Our most recent studies have focused on characterizing the biochemical and functional properties of the small rab17 GTPase. We determined that rab17 is a mono-sumoylated protein and that this modification likely mediates selective interactions with the apically-located syntaxin 2. Using polarized hepatic WIF-B cells exogenously expressing wild type, dominant...

Par3 interacts with Prickle3 to generate apical PCP complexes in the vertebrate neural plate.

Vertebrate neural tube formation depends on the coordinated orientation of cells in the tissue known as planar cell polarity (PCP). In the neural plate, PCP is marked by the enrichment of the conserved proteins Prickle3 and Vangl2 at anterior cell boundaries. Here we show that the apical determinant Par3 is also planar polarized in the neuroepithelium, suggesting a role for Par3 in PCP. Consistent with this hypothesis, interference with Par3 activity inhibited asymmetric distribution of PCP junctional comp...

Effects of Various Pharmaceutical Excipients on the Intestinal Transport and Absorption of Sulfasalazine, a Typical Substrate of BCRP Transporter.

Breast cancer resistance protein (BCRP) transporter is an efflux transporter that utilizes energy from ATP hydrolysis to push its substrates, regardless of the concentration gradient. Its presence on the apical membrane of the intestinal mucosa is a major obstacle for the intestinal absorption of its substrates. In this study, we examined the effects of various pharmaceutical excipients on the intestinal transport and absorption of sulfasalazine, a BCRP substrate. Four excipients, including 0.05% and 0.075%...

Adjuvant agents enhance round window membrane permeability to dexamethasone and modulate basal to apical cochlear gradients.

Newly Synthesized Polycystin 1 Takes Different Trafficking Pathways to the Apical and Ciliary Membranes.

Mutations in the genes encoding polycystin 1 (PC1) and polycysin 2 (PC2) cause Autosomal Dominant Polycystic Kidney Disease (ADPKD). These transmembrane proteins co-localize in the primary cilia of renal epithelial cells, where they may participate in sensory processes. PC1 is also found in the apical membrane when expressed in cultured epithelial cells. PC1 undergoes autocatalytic cleavage, producing an extracellular N-terminal fragment that remains non-covalently attached to the transmembrane C-terminus. ...

Mechanism of luminal ATP activated chloride secretion in a polarized epithelium.

There are both secretory and absorptive pathways working in tandem to support ionic movement driving fluid secretion across epithelia. The mechanisms exerting control of fluid secretion in the oviduct is yet to be fully determined. This study explored the role of apical or luminal extracellular ATP (ATPe)-stimulated ion transport in an oviduct epithelium model, using the Ussing chamber short-circuit current (Isc) technique. Basal Isc in oviduct epithelium in response to apical ATPe comprises both chloride s...

Effects of loxoprofen on the apical root resorption during orthodontic tooth movement in rats.

Studies have revealed that severe apical root resorption during tooth movement is caused by the noninfective inflammatory reaction of apical root tissues. We hypothesized that loxoprofen can suppress apical root resorption during tooth movement. Cyclic tensile force (CTF) of 10 kPa was applied to the human pulp cells for 48 hours by the Flexcell Strain Unit. Loxoprofen (10 and 100 μM) was added to the culture cells, and expression of cyclooxygenase (COX)-1, COX-2, interleukin (IL)-1β, receptor activator o...

Apical PtdIns(4,5)P is required for ciliogenesis and suppression of polycystic kidney disease.

Cilia are hair-like structures that function like antennae to detect chemical and mechanical signals in the environment. Recently, phosphoinositides were shown to play an important role in cilia assembly and disassembly. However, the precise molecular and cellular mechanisms underlying this process remain unknown. Here, we report that suppression of apical phosphatidylinositol 4,5- bisphosphate [PtdIns(4,5)P], by overexpressing apically targeted PtdIns(4,5)P phosphatase or by knocking down type I phosphatid...

Projecting Pharmaceutical Expenditure in EU5 to 2021: Adjusting for the Impact of Discounts and Rebates.
