Project description:Body temperature is maintained in a narrow range in mammals, primarily controlled by sweating. In humans, the dynamic thermoregulatory organ, comprised of 2-4 million sweat glands distributed over the body, can secrete up to 4 liters of sweat per day1, thereby making it possible to withstand high temperatures and run long distances. The genetic basis for sweat gland function, however, is largely unknown. We find that a forkhead transcription factor, FoxA1, is required to generate mouse sweating capacity. When FoxA1 is ablated, mice are otherwise healthy and sweat gland morphogenesis occurs, but no sweating ensues, with the Nkcc1 sodium/potassium/chloride co-transporter and a specialized Ca2+-activated bicarbonate channel protein, Best2, both sharply down-regulated, and glycoprotein accumulating in gland lumens and ducts. Furthermore, Best2 knockout mice display comparable anhidrosis and glycoprotein accumulation. These findings link earlier observations that both sodium/potassium/chloride exchange and Ca2+ are required for sweat production. FoxA1 is inferred to regulate two corresponding features of sweat secretion. One, via Best2, catalyzes a bicarbonate gradient that could help to drive calcium-associated ionic transport; the other, requiring Nkcc1, facilitates monovalent ion exchange into sweat. These mechanistic components can be pharmaceutical targets to defend against hyperthermia and alleviate defective thermoregulation in the elderly2, and may provide a model relevant to more complex secretory processes. For expression profiling of FoxA1, hairless fore footpad skin (6) was collected from FoxA1 knockouts and wild-type littermates at P10, P14 and P31. Three skin samples from 3 embryos for each genotype at each time point were used for biological replicates. Total RNAs were isolated with Trizol (Invitrogen), precipitated by 7.5M LiCl (Ambion), and cyanine-3-labeled cRNAs were hybridized to the NIA Mouse 44K Microarray v3.0 (Agilent Technologies). Triplicate data were analyzed by ANOVA (6). Genes with FDR<0.05, fold difference>1.5 and mean log intensity>2.0 were considered to be significant.

Project description:Sweat glands play a fundamental role in thermal regulation in man, but the molecular mechanism of their development remains unknown. To initiate analyses, we compared the model of Eda mutant Tabby mice, in which sweat glands were not formed, to wild-type mice. We inferred developmental stages and critical genes based on observations at 7 time points spanning embryonic, postnatal and adult life. In wild-type footpads, sweat gland germs were detected at E17.5. The coiling of secretory portions started at postnatal day 1 (P1), and sweat gland formation was essentially complete by P5. Consistent with a controlled morphological progression, expression profiling revealed stage-specific gene expression changes. Similar to the development of hair follicles the other major skin appendage controlled by EDA sweat gland induction and initial progression was accompanied by Eda-dependent up-regulation of the Shh pathway. During the further development of sweat gland secretory portions, Foxa1 and Foxi1, not at all expressed in hair follicles, were progressively up-regulated in wild-type but not in Tabby footpads. Upon completion of wild-type development, Shh declined to Tabby levels, but Fox family genes remained at elevated levels in mature sweat glands. The results provide a framework for the further analysis of phased downstream regulation of gene action, possibly by a signaling cascade, in response to Eda.
