Estrogenic Modulation of Ionic Channels, Pumps and Exchangers in Airway Smooth Muscle. Int J Mol Sci 2023; 24:ijms24097879. [PMID: 37175587 PMCID: PMC10178541 DOI: 10.3390/ijms24097879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 02/28/2023] [Accepted: 02/28/2023] [Indexed: 05/15/2023] Open
Abstract
To preserve ionic homeostasis (primarily Ca2+, K+, Na+, and Cl-), in the airway smooth muscle (ASM) numerous transporters (channels, exchangers, and pumps) regulate the influx and efflux of these ions. Many of intracellular processes depend on continuous ionic permeation, including exocytosis, contraction, metabolism, transcription, fecundation, proliferation, and apoptosis. These mechanisms are precisely regulated, for instance, through hormonal activity. The lipophilic nature of steroidal hormones allows their free transit into the cell where, in most cases, they occupy their cognate receptor to generate genomic actions. In the sense, estrogens can stimulate development, proliferation, migration, and survival of target cells, including in lung physiology. Non-genomic actions on the other hand do not imply estrogen's intracellular receptor occupation, nor do they initiate transcription and are mostly immediate to the stimulus. Among estrogen's non genomic responses regulation of calcium homeostasis and contraction and relaxation processes play paramount roles in ASM. On the other hand, disruption of calcium homeostasis has been closely associated with some ASM pathological mechanism. Thus, this paper intends to summarize the effects of estrogen on ionic handling proteins in ASM. The considerable diversity, range and power of estrogens regulates ionic homeostasis through genomic and non-genomic mechanisms.

Abstract
BACKGROUND & AIMS The reason that women have a lower prevalence of duodenal ulcer is not clear. We investigated whether estrogen regulates human duodenal bicarbonate secretion (DBS) and whether this process accounts for sex differences in the prevalence of duodenal ulcer. METHODS We performed an epidemiologic study to correlate duodenal ulcer prevalence with sex and age. Proximal DBS was measured from healthy subjects. Estrogen-receptor expression was examined in human duodenal mucosa by immunoblot and immunohistochemical analyses. RESULTS Among women, the prevalence of duodenal ulcer was significantly lower than among men. The reduced prevalence was greatest among premenopausal women (20-49 y), who were 3.91- to 5.09-fold less likely to develop duodenal ulcers than age-matched men; the difference was reduced to 1.32-fold or less among subjects aged 60 years or older. Premenopausal (20-29 y), but not postmenopausal (60-69 y), women had significantly higher basal and acid-stimulated DBS than the age-matched men. Basal and acid-stimulated DBS in premenopausal women (20-29 y) were significantly higher than in postmenopausal women (60-69 y), whereas there were no significant differences in basal or acid-stimulated DBS between men who were aged 20-29 years or 60-69 years. Serum levels of estradiol changed in parallel with basal and acid-stimulated DBS during the physiological menstrual cycle in premenopausal women. 17β-estradiol-stimulated DBS was independent of age or sex. Estrogen receptors α and β were detected on plasma membranes and in the cytosol of human duodenal epithelial cells. CONCLUSIONS Estrogen regulates human DBS, which could reduce the risk for duodenal ulcer in women and contribute to sex differences in the prevalence of duodenal ulcer.

Abstract
OBJECTIVE Individuals with cystic fibrosis (CF) have exercise intolerance and skeletal muscle weakness not solely attributable to physical inactivity or pulmonary function abnormalities. CF transmembrane conductance regulator (CFTR) has been demonstrated in human bronchial smooth and cardiac muscle. Using (31)P-magnetic resonance spectroscopy of skeletal muscle, we showed CF patients to have lower resting muscle adenosine triphosphate and delayed phosphocreatine recovery times after high-intensity exercise, suggesting abnormal muscle aerobic metabolism; and higher end-exercise pH values, suggesting altered bicarbonate transport. Our objective was to study CFTR expression in human skeletal muscle. METHODS AND RESULTS We studied CFTR expression in human skeletal muscle by Western blot with anti-CFTR antibody (Ab) L12B4 and demonstrated a single band with expected molecular weight of 168kDa. We isolated the cDNA by reverse transcription polymerase chain reaction and directly sequenced a 975bp segment (c. 3,600-4,575) that was identical to the human CFTR sequence. We showed punctate staining of CFTR in sarcoplasm and sarcolemma by immunofluorescence microscopy with L12B4 Ab and secondary Alexa 488-labeled Ab. We confirmed CFTR expression in the sarcotubular network and sarcolemma by electron microscopy, using immunogold-labeled anti-CFTR Ab. We observed activation of CFTR Cl(-) channels with iodide efflux, on addition of forskolin, 3-isobutyl-1-methyl-xanthine, and 8-chlorphenylthio-cyclic adenosine monophosphate, in wild-type C57BL/6J isolated muscle fibers in contrast to no efflux from mutant F508del-CFTR muscle. INTERPRETATION We speculate that a defect in sarcoplasmic reticulum CFTR Cl(-) channels could alter the electrochemical gradient, causing dysregulation of Ca(2+) homeostasis, for example, ryanodine receptor or sarco(endo)plasmic reticulum Ca(2+) adenosine triphosphatases essential to excitation-contraction coupling leading to exercise intolerance and muscle weakness in CF.

Abstract
Irreversible destruction and widening of the airways due to acquired infections or genetic mutations as well as those of unknown cause are more severe in females. Differences between male and female anatomy, behavior, and hormonal state have been proposed to explain the increased incidence and severity in females with airway disease such as cystic fibrosis (CF); however, a mechanism to explain a sex-related difference has remained elusive. In this issue of the JCI, Coakley et al. report that elevations in the major estrogen hormone in humans--17beta-estradiol--reduce Ca2+-activated Cl- secretion by airway epithelial cells in culture, thereby disrupting ion and water balance (see the related article beginning on page 4025). They measure a similar diminution of nasal epithelial Ca2+-activated Cl- secretion in women with CF during the menstrual cycle phase at which 17beta-estradiol level is at its highest. These data suggest that for about one week of a four-week menstrual cycle, women with CF will have a reduced ability to efficiently clear airway secretions, the buildup of which is a hallmark of CF. The authors suggest that these data warrant the testing of antiestrogen therapy in females with CF and propose an alternative avenue for CF therapeutic development.

Abstract
Because human duodenal mucosal bicarbonate secretion (DMBS) protects duodenum against acid-peptic injury, we hypothesize that estrogen stimulates DMBS, thereby attributing to the clinically observed lower incidence of duodenal ulcer in premenopausal women than the age-matched men. We found that basal and acid-stimulated DMBS responses were 1.5 and 2.4-fold higher in female than male mice in vivo, respectively. Acid-stimulated DMBS in both genders was abolished by ICI 182,780 and tamoxifen. Estradiol-17beta (E2) and the selective estrogen receptor (ER) agonists of ERalpha [1,3,5-Tris(4-hydroxyphenyl)-4-propyl-1H-pyrazole] and ERbeta [2,3-bis(4-hydroxyphenyl) propionitrile], but not progesterone, rapidly stimulated ER-dependent murine DMBS in vivo. E2 dose dependently stimulated murine DMBS, which was attenuated by a Cl(-)/HCO3(-) anion exchanger inhibitor 4,4'-didsothio- cyanostilbene-2, 2'-disulfonic acid, removal of extracellular Cl(-), and in cystic fibrosis transmembrane conductance regulator knockout female mice. E2 stimulated murine DMBS in vitro in both genders with significantly greater response in female than male mice (female to male ratio = 4.3). ERalpha and ERbeta mRNAs and proteins were detected in murine duodenal epithelium of both genders; however, neither ERalpha nor ERbeta mRNA and protein expression levels differed according to gender. E2 rapidly mobilized intracellular calcium in a duodenal epithelial SCBN cell line that expresses ERalpha and ERbeta, whereas BAPTA-AM abolished E2-stimulated murine DMBS. Thus, our data show that E2 stimulates DMBS via ER dependent mechanisms linked to intracellular calcium, cystic fibrosis transmembrane conductance regulator, and Cl(-)/HCO3(-) anion exchanger. Gender-associated differences in basal, acid- and E2-stimulated DMBS may have offered a reasonable explanation for the clinically observed lower incidence of duodenal ulcer in premenopausal women than age-matched men.
