High impact information on Poecilia

• Exocrine pancreatic neoplasms developed in the guppy Poecilia reticulata following a single brief exposure to methylazoxymethanol acetate [(MAM-Ac) CAS: 592-62-1] [1].
• Previously reported inhibitions of heart lactate dehydrogenase (Guppy, M., and Hochachka, P.W. (1978) J. Biol. Chem. 253, 8465-8469) and muscle pyruvate kinase (Kemp, R.G. (1973) J. Biol. Chem. 248, 3963-3967) by creatine phosphate are due to oxalate which is a contaminant found in some commercial preparations of creatine phosphate [3].
• Application of this technique for detection of lithium concentrations in plasma and tissues of Poecilia was the purpose of this investigation [4].
• Countergradient variation in the sexual coloration of guppies (Poecilia reticulata): drosopterin synthesis balances carotenoid availability [5].
• 17alpha-ethinylestradiol reduces the competitive reproductive fitness of the male guppy (Poecilia reticulata) [6].

Chemical compound and disease context of Poecilia

• To evaluate the usefulness of histopathology in aquatic toxicity testing, studies were carried out on the small freshwater fish Poecilia reticulata (guppy) following aqueous methyl mercury chloride exposure [7].
• Investigation of acute toxicity of chlorpyrifos-methyl on guppy Poecilia reticulata [8].

• Investigation of acute toxicity of beta-cypermethrin on guppies Poecilia reticulata [10].
• Investigation of acute toxicity and the effect of cadmium chloride (CdCl2 . H2O) metal salt on behavior of the guppy (Poecilia reticulata) [11].

Biological context of Poecilia

• Transient occurrence of chloride cells in the abdominal epidermis of the guppy, Poecilia reticulata Peters, adapted to sea water [12].
• Chloride cells are extremely rare in the epidermis of the guppy, Poecilia reticulata Peters, adapted to fresh water [12].
• DNA sequence analyses suggest that the genes cloned include the guppy homologue of Krox-20 and the zebrafish homologue of Krox-24, and that these genes diverged prior to the separation of the lineages leading to teleosts and to mammals [13].
• Thus, on the present results, the role of any particular steroid in maintaining gestation of the guppy is not obvious [14].
• Influence of survival time on the lethal body burden of 2,3,4,5-tetrachloroaniline in the guppy, Poecilia reticulata [15].

Anatomical context of Poecilia

• Norepinephrine (NE) and phenylephrine (Phe) were employed to study the ionic requirements for alpha adrenoceptor activation in the teleost Poecilia reticulata melanophores [16].
• Terminal processes of serotonin neurons in the caudal spinal cord of the molly, Poecilia latipinna, project to the leptomeninges and urophysis [17].
• Male black mollies treated with methyl-testosterone have significantly smaller GTH-cells and a lesser number of secretory vesicles and mitochondria in these cells [18].
• The metabolism in vitro of various radiolabeled steroid precursors by isolated ovarian follicles at various stages of the reproductive cycle and extrafollicular (EF) tissue of the guppy was investigated [19].
• We studied the central projections of the mesencephalic nucleus of the trigeminal nerve (MesV) in the guppy (Lebistes reticulatus), after application of horseradish peroxidase or fluorescein dextran amine into the eye orbit [20].

Associations of Poecilia with chemical compounds

• Male guppies appear to use drosopterin pigments in a manner that dilutes, but does not eliminate, the indicator value of carotenoid coloration [21].
• Groups of male guppies were exposed to 10.5, 44.4, or 112 ng/L of the synthetic estrogen 17alpha-ethinylestradiol (EE2) from birth to adulthood [6].
• The effects of vinclozolin, an anti-androgenic fungicide, on male guppy secondary sex characters and reproductive success [22].
• For a period of 30 days, groups of adult male guppies were exposed to vinclozolin, p,p'-DDE, or the therapeutic antiandrogen flutamide (used as positive control) applied to the fodder at concentrations between 0.1 and 100 microg/g fodder [23].
• We report that the orange spots that male guppies (Poecilia reticulata) display to females contain red pteridine pigments (drosopterins) in addition to carotenoids [21].

Gene context of Poecilia

• In vitro effects of thyrotropin-releasing hormone and somatostatin on prolactin and growth hormone release by the pituitary of Poecilia latipinna. I. An electrophoretic study [24].
• Using the electron-microscopic immunogold method, vasotocin, isotocin, somatostatin (SRIF), gonadotrophin-releasing hormone (LHRH) and corticotrophin-releasing factor (CRF)-like immunoreactivities were localized in separate neurosecretory fibres in the pituitary of a teleost fish Poecilia latipinna [25].
• Ultrastructural characterization of neurosecretory fibres immunoreactive for vasotocin, isotocin, somatostatin, LHRH and CRF in the pituitary of a teleost fish, Poecilia latipinna [25].

• Ionic requirements for melanin concentrating hormone (MCH) actions on teleost Poecilia reticulata melanophores [27].

Analytical, diagnostic and therapeutic context of Poecilia

• Atlantic mollies (Poecilia mexicana) inhabit a variety of surface habitats, but they also occur in a sulfur cave in southern Mexico. We examined male mate choice relative to female body size in the cave population and in the most closely related surface-dwelling population from a nearby river [28].
• Static bioassays were made to determine acute toxicity of chlorpyrifos-methyl, a wide spectrum organophosphorus insecticide and potential toxic pollutant of aquatic ecosystem, Guppy fish (Poecilia reticulata) [8].
• Chromosomes of the Amazon molly, Poecilia formosa, a unisexual species of hybrid origin, were investigated by C-banding, silver staining, and fluorescent staining with DAPI, quinacrine dihydrochloride, and chromomycin A3 [29].
