Diet-induced obesity impairs mammary development and lactogenesis in murine mammary gland.
We have developed a mouse model of diet-induced obesity that shows numerous abnormalities relating to mammary gland function. Animals ate approximately 40% more calories when offered a high-fat diet and gained weight at three times the rate of controls. They exhibited reduced conception rates, increased peripartum pup mortality, and impaired lactogenesis. The impairment of lactogenesis involved...
متن کاملUltrasonographic Examination of Mammary Glands in Caspian Mares during the Lactation and Dry Period
Objective- The aim of this study was to determine the normal ultrasonographic and morphologic appearance of mammary gland and teat in Caspian mares during lactation and dry period. Design- Experimental study. Animals- Seven mature Caspian mares Procedures- Using a 6.5-8.5 MHz linear transducer the ultrasonographic appearance of lactating and dry mammary glands was determined in 7 mature Casp...
متن کاملMammary Gland Specific Knockdown of the Physiological Surge in Cx26 during Lactation Retains Normal Mammary Gland Development and Function
Connexin26 (Cx26) is the major Cx protein expressed in the human mammary gland and is up-regulated during pregnancy while remaining elevated throughout lactation. It is currently unknown if patients with loss-of-function Cx26 mutations that result in hearing loss and skin diseases have a greater susceptibility to impaired breast development. To investigate if Cx26 plays a critical role in mamma...
متن کاملThe mammary souffle of pregnancy and lactation.
IN 1908 van den Bergh' described a loud systolic murmur of unusual quality that appeared in a woman the day after parturition. It was localized to a small area in the second right intercostal space, and disappeared entirely when firm pressure with the stethoscope bell was applied over the site of maximum intensity. He believed the murmur was extracardiae, and owed its origin to enlarged tortuou...
متن کاملAdaptations in lipid metabolism of bovine adipose tissue in lactogenesis and lactation.
The timing and magnitude of metabolic adaptations in adipose tissue during lactogenesis and lactation were determined in first lactation bovines. In vitro rates of lipogenesis and palmitate esterification were measured to estimate in vivo synthesis. Lipolysis was measured in the basal state and as maximally stimulated by norepinephrine or epinephrine to estimate physiological adaptations as wel...
