Variants within STK39 are associated with susceptibility to essential hypertension, and constitutively active SPAK mice are hypertensive and hyperkalemic, similar to familial hyperkalemic hyperkalemia in humans. SPAK null mice are hypotensive and mimic Gitelman syndrome, a rare monogenic salt wasting human disorder. Mice exhibit nephron segment-specific expression of full length SPAK and N-terminally truncated SPAK isoforms (SPAK2 and KS-SPAK) with impaired kinase function. SPAK2 and KS-SPAK function to inhibit phosphorylation of cation co-transporters by full length SPAK. However, the existence of orthologous SPAK2 or KS-SPAK within the human kidney, and the role of such SPAK isoforms in nephron segment-specific regulation of Na+ reabsorption, still have not been determined. In this study, we examined both human and mouse kidney transcriptomes to uncover novel transcriptional regulation of STK39. We established that humans also express STK39 transcript isoforms similar to those found in mice but differ in abundance and are transcribed from human-specific promoters. In summary, STK39 undergoes species-specific transcriptional regulation, resulting in differentially expressed alternative transcripts that have implications for the design and testing of novel SPAK-targeting antihypertensive medications. © 2020 The Authors.

Effective therapeutic treatment of this condition has been hampered by the unknown etiology and lack of understanding of cellular and molecular mechanisms that underlie idiopathic oligohydramnios. Amniotic fluid volume (AFV) is determined by intramembranous (IM) transport of amniotic fluid across the amnion and this pathway is regulated to maintain AFV within the normal range. To gain understanding of the causes of idiopathic oligohydramnios, we performed proteomics analysis of the human amnion to investigate the changes in protein expression profiles of cellular transport pathways and regulators in patients with oligohydramnios. Placental amnions from five patients with normal pregnancies and five patients with oligohydramnios were subjected to proteomics experiments followed by bioinformatics analysis.

However, the effects of neonatal BPA exposure on pubertal development has not been described. In this study, female Sprague-Dawley rats were exposed to 0.05, 0.5, 5, or 10 mg·kg-1 ·day-1 BPA, or corn oil vehicle alone from postnatal day 1 (PND1) to PND10 via subcutaneous injection. We evaluated day of vaginal opening (DVO), ovarian morphology, serum hormone concentrations, and hypothalamic expression of Gnrh1 and Kiss1 in female rats at PND35. DVO was significantly advanced in rats exposed to 5 and 10 mg·kg-1 ·day-1 BPA. find more Serum hormone concentrations increased as BPA dose increased. Additionally, hypothalamic Gnrh1 and Kiss1 expression were increased with BPA exposure; rats exposed to 10 mg·kg-1 ·day-1 BPA had significantly upregulated hypothalamic Gnrh1 and Kiss1 expressions in terms of both messenger RNA and protein levels. Our results suggest that exposure to a 10 mg·kg-1 ·day-1 dose of BPA might advance pubertal development significantly. In addition, within the range of 0 to 10 mg·kg-1 ·day-1 , neonatal exposure to BPA may affect pubertal development in a dose-dependent manner. © 2020 Wiley Periodicals, Inc.Australians want to live at home as they age and seek support from health and social care services to achieve this. The consumer driven market-based approach to community services in Australia has resulted in an increases in user's expectations of quality. What constitutes a quality service from the consumer's perspective is an important agenda to understand as the focus of care delivery moves to the domiciliary setting. This paper presents one aspect from a grounded theory PhD study, the aim of which was to understand the lived experience of receiving services in the home and its impact on the meaning of home. Participants were 11 people with dementia and 18 family supporters living in the state of Victoria, Australia. Data were collected between 2015 and 2017 through multiple interviews, photographic images, field notes and memos. NVIVO 10 qualitative analysis software program was used to support constant comparative analysis. Using a grounded theory approach, this study found that the decision to engage with community services was driven by the need to maintain autonomy, self-identity and home life. Participants sought quality services but discovered a dichotomy of positive and negative aspects in the way services were delivered. The most common reaction to the experience of poor-quality care was to reflect on their expectations for care quality; and manage the reality of what was delivered. Team work and service responsiveness were positive characteristics but were offset by service limitations and inefficiencies caused by poor communication and poor staff retention. The interpersonal relationships that participants developed with staff was highlighted; trust was an important factor whereas unreliable, task orientated and poorly trained staff would be rejected. The implications for policy and practice are described. © 2020 John Wiley & Sons Ltd.Puberty in girls represents a notable period of vulnerability for different psychological disorders. The research literature has primarily considered external and contextual factors that might explain these rises in symptomatology. In the present study, we investigate relations of pubertal status and timing with individual cognitive, emotional, and behavioral tendencies, commonly identified as transdiagnostic processes, in a sample of N = 228 girls (Mage  = 11.75 years). We also test whether these transdiagnostic processes mediate associations of pubertal status and pubertal timing with depressive symptoms. Results support greater endorsement of rumination, co-rumination, negative urgency, and both anxious and angry rejection sensitivity in girls with more advanced pubertal status, as well as in girls with early pubertal timing. Higher levels of transdiagnostic processes fully mediated associations of pubertal status and timing with depressive symptoms at significant and marginally significant levels, respectively.
