“…According to Perry and Tzaneva ( 2016 ), like in mammalian glomus cells (Summers et al, 1999 ), NO may inhibit ion channels involved in neurosecretion. This is supported by the NO-dependent regulation of intracellular Ca 2+ observed in the melanophore of the Indian snakehead Channa punctatus (Biswas et al, 2011 ) and in the growth hormone release of goldfish (Chang et al, 2014 ). Apart from its putative involvement in O 2 chemoreception, in teleosts, as well as in mammals, NO may play a role in the hypoxia-elicited response via a modulation of the ventilatory performance.…”

Changes in environmental oxygen (O2) are naturally occurring phenomena which ectotherms have to face on. Many species exhibit a striking capacity to survive and remain active for long periods under hypoxia, even tolerating anoxia. Some fundamental adaptations contribute to this capacity: metabolic suppression, tolerance of pH and ionic unbalance, avoidance and/or repair of free-radical-induced cell injury during reoxygenation. A remarkable feature of these species is their ability to preserve a normal cardiovascular performance during hypoxia/anoxia to match peripheral (tissue pO2) requirements. In this review, we will refer to paradigms of hypoxia- and anoxia-tolerant teleost fish to illustrate cardiac physiological strategies that, by involving nitric oxide and its metabolites, play a critical role in the adaptive responses to O2 limitation. The information here reported may contribute to clarify the molecular and cellular mechanisms underlying heart vulnerability vs. resistance in relation to O2 availability.

“…In the nervous system NO acts as a signaling molecule that functions like those of a neurotransmitter and neuromodulator (Dawson and Snyder, 1994; Garthwaite and Boulton, 1995). NO also plays major role in different biological and physiological activities including memory formation and pain modulation (Snyder and Bredt, 1992) and even color change (Biswas et al, 2014, 2011).…”

Nitric oxide (NO) is a chemically diffusible molecular messenger playing various roles in both vertebrates and invertebrates. Nitric oxide synthase (NOS) is the key enzyme in synthesis of NO. The neuroanatomical distribution pattern of neuronal nitric oxide synthase (nNOS) was studied and developing stages of Labeo rohita such as hatchlings (10-15mm), frys (15-35mm), semi-fingerlings (35-65mm), fingerlings (65-100mm) and adults (350-370mm) were used. In the telencephalon, nitrergic cells were observed in both pallial and subpallial regions along with entopeduncular nucleus suggesting the involvement of NO in the control of sensory functions throughout the development. In the diencephalon, nNOS positive neurons were localized in the nucleus preopticus periventricularis and preopticus parvocellularis throughout development while nucleus preopticus magnocellularis was found immunopositive only in adult specimens who suggest the involvement of NO in the hormonal regulation. nNOS immunoreaction was also noted in suprachaismatic nucleus, habenula, lateral tuberal nucleus, paraventricular organ and anterior division of preglomerular nucleus throughout development. In the mesencephalic region, nNOS immunoreactivity was seen in the optic tectum, torus longitudinalis, nucleus of median longitudinal fascicle and occulomotor nucleus indicate the role of NO in integration of visual inputs and modulates motor control of the eyes and movements. Caudally, in the rhombencephalon, the cerebellum, the nucleus reticularis, the octaval nucleus and the motor nucleus of vagal nerve were nNOS positive during development. nNOS reactive cells and fibers were noted in the spinal motor column, thus suggesting a role of NO in gestation and startle response from early development.

A strong literature base supports the notion that active learning improves retention in the science classroom. To that end, a course was designed to allow students to develop their own experiments around a central biological question. The model system used in this particular course is control of melanosome dispersal via second messenger systems in zebrafish (Danio rerio) scales. Students start by applying agonists and antagonists to the cAMP and Ca(2+) second messenger systems, and then can progress to more refined questions with the model system. This project is advantageous because it could be easily adapted to fit the needs of many different courses and ability levels; it is relatively easy to perform; it is enjoyable to teach; and students can be largely given a free reign to decide upon the design of their experiments.
