anuran amphibian germ cells
1. The presence of a large amount of glycoconjugates on the anuran amphibian germ cells was demonstrated using fluorescein isothiocyanate lectins binding specifically to D-galactose and at a lower level, by other lectins binding specifically to iV-acetyl-galactosamine. 2. Glycoconjugates including D-galactose were found near the pseudopodial expansions and in the extracellular space, between ge...
متن کاملLocal adaptation of an anuran amphibian to osmotically stressful environments.
Water salinity is an intense physiological stress for amphibians. However, some species, such as Bufo calamita, breed in both brackish and freshwater environments. Because selection under environmentally stressful conditions can promote local adaptation of populations, we examined the existence of geographic variation in water salinity tolerance among B. calamita populations from either fresh o...
متن کاملThe insulator protein CTCF regulates Drosophila steroidogenesis
The steroid hormone ecdysone is a central regulator of insect development. In this report we show that CTCF expression in the prothoracic gland is required for full transcriptional activation of the Halloween genes spookier, shadow and noppera-bo, which encode ecdysone biosynthetic enzymes, and for proper timing of ecdysone-responsive gene expression. Loss of CTCF results in delayed and less sy...
متن کاملAcid-base regulation and blood gases in the anuran amphibian, Bufo marinus, during environmental hypercapnia.
Specimens of Bufo marinus were exposed to aerial and aquatic hypercapnia (5% CO2) in a closed, water recirculation system to evaluate mechanisms involved in the compensation of a respiratory acidosis in these animals. Arterial PCO2 was elevated from about 9 mmHg (1 mmHg = 133.3 Pa) to 35 (1 h) and 37 mmHg (2 h), and gradually approached about 40 mmHg (24 h of hypercapnia). The typical hypercapn...
متن کاملHistone methyltransferase PRDM8 regulates mouse testis steroidogenesis.
A family of PRDM proteins are similar to histone methyltransferases (HMTases) with SET domain in that they modulate different cellular processes, including transcriptional regulation, through chromatin modifying activities. By applying a bioinformatic approach, we searched for proteins containing the SET domain and identified a double zinc-finger domain containing PRDM8 with HMTase activity. In...
