Immunohistochemical analysis of Pax6 and Pax7 expression in the CNS of adult Xenopus laevis

Publication date: May 2014 Source:Journal of Chemical Neuroanatomy, Volumes 57–58 Author(s): Sandra Bandín , Ruth Morona , Jesús M. López , Nerea Moreno , Agustín González Pax6 and Pax7 are transcription factors essential for the development of the CNS. In addition, increasing data, mainly obtained in amniotes, support that they are expressed in subsets of neurons in the adult, likely playing a role in maintaining neuron type identity. In the present study we analyzed the detailed distribution of Pax6 and Pax7 cells in the adult CNS of Xenopus laevis. Immunohistochemistry with antibodies that are required for high-resolution analysis of Pax-expressing cells was conducted. A wide distribution of Pax6 and Pax7 cells throughout the CNS was detected, with distinct patterns that showed only slight overlapping. Only Pax6 was expressed in the telencephalon, including the olfactory bulbs, septum, striatum and amygdaloid complex. In the diencephalon, Pax6 and Pax7 were distinct in the alar and basal parts, respectively, of prosomere 3. Large numbers of Pax6 and Pax7 cells were distributed in the pretectal region (alar plate of prosomere 1) but only Pax6 cells extended into basal plate. Pax7 specifically labeled cells in the optic tectum, including the ventricular zone, and Pax6 cells were the only cells found in the tegmentum. Pax6 was found in most granule cells of the cerebellum and Pax7 expression was found only in the ventricular zone. In...

Chronic disturbances in glucocorticoid homeostasis, i.e. in Addison's and Cushing's disease patients, predispose to the development of atherosclerotic cardiovascular disease. Here we review preclinical and clinical findings regarding the relation between changes in plasma glucocorticoid levels and the atherosclerosis extent. It appears that, although the altered glucocorticoid function can in most...

Small molecule medicines have dominated in the past while antibodies have grown dramatically in recent years. However, the failure of traditional small and large molecules in accessing certain targets has led to increased R&D efforts to develop alternative modalities. Therapeutic oligonucleotides (ONs) can accurately be directed against their ribonucleic acid (RNA...

ConclusionsThese results demonstrate that a novel proton-coupled organic cation antiporter plays a predominant role in the blood to brain influx of AC, MA and HA at the BBB, and thus affect the safety of Aconitum species.Graphical abstract

This study investigated the cardioprotective effect of vitexin against MIRI and its possible mechanism. Isolated SD rat hearts were subjected to MIRI in a Langendorff perfusion system, and H9c2 cells were subjected to hypoxia/reoxygenation (H/R) in vitro. Ex vivo experiments showed improved left ventricular function and reduced infarct size in the vitexin group. Transmission electron microscopy showed that I/R caused outer mitochondrial membrane rupture, cristae disappearance and vacuolation, while vitexin reduced mitochondrial damage and ultimately reduced cardiomyocyte apoptosis. In vitro, vitexin protected H9c2 cells fr...

This study aimed to explore the link between block copolymers’ interfacial properties and nanoscale carrier formation and found out the influence of length ratio on these characters to optimize drug delivery system. A library of diblock copolymers of PEG-PCL and triblock copolymers with additional PEI (PEG-PCL-PEI) were synthesized. Subsequently, a systematic isothermal investigation was performed to explore molecular arrangements of copolymers at air/water interface. Then, structural properties and drug encapsulation in self-assembly were investigated with DLS, SLS and TEM. We found the additional hydrogen bond in t...
