Oligodeoxyribonucleotide excess solution hybridization, Northern blot and in situ hybridization were used to analyze metallothionein gene expression in mouse decidua and placentae during gestation. Metallothionein (MT) -I and -II mRNA levels were constitutively elevated, 11- and 13-fold, respectively, relative to the adult liver, in the deciduum (D8), and decreased coordinately about 6-fold dur...
Transcriptional regulation of the prolactin gene in the decidua differs from that in the pituitary. Several lines of evidence strongly suggest this difference is due to regulation of the prolactin gene in the decidua and other extra-pituitary tissues by tissue-specific transcription factors, which activate distinct promoters to induce prolactin gene expression in extra-pituitary sites compared ...
SUMMARY The DNA contents of mouse decidual nuclei were estimated by microdensitometry and ploidies of up to 64 times the haploid DNA content were found. Electrophoretic studies, using the enzyme marker glucose phosphate isomerase (GPI-1), on decidual giant and multinucleate cells from a mouse chimera, revealed that cell fusion was not the mechanism of formation of such cells. The development of...
میوههای رسیده (میوههای با پوست و گوشت صورتی مایل به قرمز) و نارس (میوههای سبز رنگ با گوشت صورتی رنگ) کلیر در اواسط خرداد ماه 1380 از رویشگاه طبیعی کلیر در منطقه سیریک (واقع در 80 کیلومتری شرق میناب) جمعآوری گردید و بلافاصله به آزمایشگاه منتقل شدند. بهطور مجزا از میوههای رسیده و نارس نمونهبرداری شد و در آزمایشگاه صنایع غذایی مرکز تحقیقات منابع طبیعی و امور دام هرمزگان ارزش غذایی آن اندا...
Upper treeline ecotones are important life form boundaries and particularly sensitive to a warming climate. Changes in growth conditions at these ecotones have wide-ranging implications for the provision of ecosystem services in densely populated mountain regions like the European Alps. We quantify climate effects on short- and long-term tree growth responses, focusing on among-tree variability...
BACKGROUND Early pregnancy loss (EPL) is a frustrating clinical problem, whose mechanisms are not completely understood. DNA methylation, which includes maintenance methylation and de novo methylation directed by DNA methyltransferases (DNMTs), is important for embryo development. Abnormal function of these DNMTs may have serious consequences for embryonic development. METHODS To evaluate the...
