هدف:کورکومین دارای خواص آنتی اکسیدانی و ضدالتهابی است. القای بیانaqp5، عضوی از خانواده آکواپورین ها، از پروتئین های کانال آبی غشایی، در مراحل اولیه سرطان روده این حدس را بر می انگیزد که aqp5 یک نیروی به پیش برنده در آغاز سرطانزایی روده است. . فرض بر آن بود که کورکومین می تواند سطوح پروتئین آکواپورین 5 را در سلولهای سرطانی روده hct116 کاهش دهد. مواد و روشها: سلولهای سرطانی روده hct116 در محیط ...
Chorda tympani denervation (CTD) of rats was earlier shown to result in loss of submandibular gland (SMG) weight (at only 1 wk) and in continued reduction in aquaporin 5 (AQP5) protein expression (until 4 wk), without affecting its mRNA synthesis (Li X, Azlina A, Karabasil MR, Purwanti N, Hasegawa T, Yao C, Akamatsu T, Hosoi K. Am J Physiol Gastrointest Liver Physiol 295: G112-G123, 2008). The ...
AIMS The etiologies of Ménière's disease and idiopathic sudden sensorineural hearing loss (SSNHL) remain unclear. The homeostasis of the water and blood circulation in the inner ear is essential for maintaining its hearing and equilibrium functions, and aquaporins and estrogen are involved in the fluid or ion balance in the inner ear. We investigated the associations between genetic polymorphis...
Developmental expression of aquaporin water transport proteins is not well understood in respiratory tract or secretory glands; here we define aquaporin protein ontogeny in rat. Expression of aquaporin-3 (AQP3), AQP4, and AQP5 proteins occurs within 2 wk after birth, whereas AQP1 first appears before birth. In most tissues, aquaporin protein expression increases progressively, although transien...
We have previously shown that AQP5 and BTF3 genetic variation and expression in whole saliva are associated with caries experience suggesting that these genes may have a functional role in protecting against caries. To further explore these results, we tested ex vivo if variants in these genes are associated with subclinical dental enamel mineral loss. DNA and enamel samples were obtained from ...
The water channel aquaporin 1 (AQP1) and certain Rh-family members are permeable to CO(2) and NH(3). Here, we use changes in surface pH (pH(S)) to assess relative CO(2) vs. NH(3) permeability of Xenopus oocytes expressing members of the AQP or Rh family. Exposed to CO(2) or NH(3), AQP1 oocytes exhibit a greater maximal magnitude of pH(S) change (DeltapH(S)) compared with day-matched controls in...
In order to gain insight into the molecular mechanisms that allow taste cells to respond to changes in their osmotic environment, we have used primarily immunocytochemical and molecular approaches to look for evidence of the presence of aquaporin-like water channels in taste cells. Labeling of isolated taste buds from the fungiform, foliate, and vallate papillae in rat tongue with antibodies ag...
30 سر موش صحرایی به گروه های کنترل، کورکومین و نانوکورکومین تقسیم شدند. کلیه حیوانات داروی کارسینوژنیک آزوکسی متان (15 mg/kg, s.c) را هفته ای یک بار و به مدت دو هفته متوالی دریافت کردند. حیوانات در گروه های کورکومین و نانوکورکومین تا هفته 22 (از دو هفته قبل از تزریق آزوکسی متان تا 14 هفته بعد از آخرین تزریق آزوکسی متان) به ترتیب کورکومین 2/0 درصد و نانوکورکومین را دریافت نمودند. در پایان مطالعه...
Milk secretion involves significant flux of water, driven largely by synthesis of lactose within the Golgi apparatus. It has not been determined whether this flux is simply a passive consequence of the osmotic potential between cytosol and Golgi, or whether it involves regulated flow. Aquaporins (AQPs) are membrane water channels that regulate water flux. AQP1, AQP3 and AQP5 have previously bee...
