S100 A9 is expressed and secreted by the oviduct epithelium, interacts with gametes and affects parameters of human sperm capacitation in vitro
(Wiley, 2019-10)
Our previous findings demonstrate that some oviductal secretion proteins bind to gametes and affect sperm physiology and gamete interaction. One of these proteins possesses an estimated molecular weight of 14 kDa. The ...
Changes in islet plasma membrane calcium-ATPase activity and isoform expression induced by insulin resistance
(Elsevier Science Inc, 2009-10)
We studied the effect of insulin resistance (IR) induced by administration of a fructose-rich diet (FRD) to normal Wistar rats for 21 days, upon islet plasma membrane calcium ATPases (PMCAs) and insulin secretion. FRD rats ...
Genetic Analysis of Signal Peptides in Amphibian Antimicrobial Secretions
(Indian Academy of Sciences, 2018-12)
Amphibian secretion is an important source of bioactive molecules that naturally protect the skin against noxious microorganisms. Collectively called antimicrobial peptides (AMPs), these molecules have a wide spectrum of ...
Synthesis and secretion of volatile short-chain fatty acids in Triatoma infestans infected with Beauveria bassiana
(Wiley Blackwell Publishing, Inc, 2018-09)
Physically disturbed Triatoma infestans (Hemiptera: Reduviidae) adults, as well as adults of other Chagas' disease vectors, secrete a mix of volatile organic compounds (VOCs) with alarm and possible sexual and defence ...
Low-Molecular-Mass Penicillin Binding Protein 6b (DacD) Is Required for Efficient GOB-18 Metallo--Lactamase Biogenesis in Salmonella enterica and Escherichia coli
(American Society For Microbiology, 2014-01)
Metallo--lactamases (MBLs) are Zn2-containing secretory enzymes of clinical relevance, whose final folding and metal ion assembly steps in Gram-negative bacteria occur after secretion of the apo form to the periplasmic ...
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
(Academic Press Ltd - Elsevier Science Ltd, 2018-11)
After gene duplication, paralogous genes evolve independently, and consequently, the new proteins encoded by these duplicated genes are exposed to changes in their subcellular location. Although there are increasing evidence ...
Cadmium mimics estrogen-driven cell proliferation and prolactin secretion from anterior pituitary cells
(Public Library of Science, 2013-11-13)
Cadmium (Cd) is a heavy metal of considerable occupational and environmental concern affecting wildlife and human health. Recent studies indicate that Cd, like other heavy metals, can mimic effects of 17β-estradiol (E2) ...
Branched-Chain Amino Acid-Enriched Diet: Effects on Insulin Secretion and Cellular Immune Aggression
(Wiley Blackwell Publishing, Inc, 2008-07)
<p class="abstract">Several reports have demonstrated that high-protein diets may have beneficial effects on experimental models of diabetes and have raised the possibility that branched-chain amino acids could play a role ...
Rab Proteins: Insights into Intracellular Trafficking in Endometrium
(SAGE Publications, 2020-07)
Rab proteins belong to the Ras superfamily of small monomeric GTPases. These G proteins are the main controllers of vesicular transport in every tissue, among them, the endometrium. They are in charge of to the functional ...
Nectar ecology of the endemic epiphytic hummingbird-pollinated bromeliad vriesea altodaserrae: Secretion dynamics and pollinator visitation pattern
(Sociedade Botanica do Brasil, 2018-07)
Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators. Considering the specialization of hummingbird-pollinated bromeliads, ...
