Article Title: Sex Differences in the Effects of Etonogestrel on Respiratory Recovery in an In Vivo Rat Model of Central Chemoreflex Impairment
doi: 10.1111/apha.70194
Figure Lengend Snippet: Molecular changes following ETO administration in the retrotrapezoid nucleus (RTN), the solitary tract nucleus (NTS), and the medial hypothalamus (MH) of female and male rats. (A–C) Quantitative PCR analysis of Nmb , transcription factor Phox2b , and proton‐sensing channels, Gpr4 and Task2 , in the RTN (A), NTS (B), and MH (C) of females and males. Naive males showed higher expression levels of Nmb and Gpr4 in the RTN (A) and Phox2b , Gpr4 , and Pgr in the NTS (B) compared with females. Following lesion or ETO treatment, Nmb expression was significantly reduced in both SHAM‐ and ETO‐treated animals compared with naive controls, in males and females (A). ETO‐treated females showed upregulation of Task2 and Gpr4 mRNA levels in the RTN (A), and downregulation of Phox2b and Task2 mRNA levels in the NTS (B), consistent with the observed recovery of the CO 2 chemoreflex. No significant changes were observed in the MH (C). In males, no significant transcriptional changes were detected in the RTN, NTS, or MH, except for the reduction of Nmb in the RTN. Graphs show mean ± SD with individual values represented as 2 −ΔCt with all statistical analyses performed on ΔCt values. Comparisons between naive males and females were analyzed using unpaired t ‐tests or Mann–Whitney U tests, whereas differences among experimental groups within each sex were analyzed using one‐way ANOVA (Tukey post hoc) or Kruskal–Wallis ANOVA (Dunn's post hoc). * p < 0.05, ** p < 0.01, *** p < 0.001.

Rabies labeled input neurons were largely (74.5 ± 1.1% SEM) restricted to the medulla (pink, MY) and exhibited a slight but consistent ipsilateral bias (55.6 ± 3.0% SEM). Major sources of these medullary inputs were the intermediate, gigantocellular, and parvocellular reticular nuclei. Inputs from the cortex, midbrain, and pons represented a minority of rabies-labeled neurons (1.6 ± 0.3% SEM, 6.4 ± 0.5% SEM, and 12.3 ± 1.1% SEM respectively). c – g Images at low magnification (left) and high magnification (right) of monosynaptic input neurons in the IRt, Peri5, mesencephalic nucleus of the trigeminal nerve, contralateral superior colliculus, and motor cortex.

Figure Lengend Snippet: GD2 and lineage marker expression in TH-MYCN tumors, primary explants and cell lines, and human neuroblastoma cell lines. (a) TH-MYCN +/+ neuroblastomas (NB), previously established and propagated TH-MYCN +/+ and human NB cell lines were examined for surface GD2 expression by flow cytometry in single, live, CD45- cells, and NCAM1+ and CD56+ for mouse and human NBs, respectively. Cell lines were passaged for 3 weeks to assess GD2 stability. (b) Fresh TH-MYCN +/+ tumors were explanted and carried in tissue culture to monitor the GD2+ proportion of tumor cells over time ex vivo. (c) Immunoblot detection of a principal adrenergic marker, Phox2b, principal mesenchymal marker, Yap1, and β-tubulin loading control. IMR5 and SHEP are neuroblastoma cell lines with a predominantly adrenergic or mesenchymal lineage, respectively. TH-MYCN +/+ primary tumors are predominantly adrenergic marker expressing. TH-MYCN +/+ tumor-derived cell lines are largely mesenchymal marker expressing when propagated ex vivo (>3 months, 3000-series cell lines) whereas marker expression is heterogeneous during earlier passage ex vivo (5000-series cell lines). (d) Immunocytochemistry and immunohistochemistry to detect Phox2b and Yap1 from FFPE cell line pellets or primary tumors are shown, concordant with immunoblot results.
