Somatostatin (SST) is a neuropeptide hormone that regulates the release of secondary hormones. Evidence suggests SST plays a neuromodulatory role due to its distribution throughout the central nervous system. Interestingly, SST has been suggested to affect the carotid body, the small peripheral chemoreceptors that regulate breathing. It has been shown that the peripheral chemoreflex sensitivity to CO2 and hypoxia is reduced by SST in humans (Pedersen et al., 1999; Pandit et al., 2014). SST has also been found to inhibit whole cell Ca2+ currents recorded from adult rat carotid body type I cells (e Silva & Lewis, 1995), but the …

Malignant transformation is the process by which cells develop cancer properties. While many causes for malignant transformation are known (i.e. common genetic mutations and/or exposure to toxins or viruses), the basic requirements that allow a cell to stay alive with altered nutrient and energy requirements are just now being studied. In some tumor types malignant cells undergo changes that result in metabolic differences compared to normal cells. These can include defects in mitophagy resulting in an accumulation of dysfunctional mitochondria and/or a metabolic switch resulting in increased glycolysis, termed the Warburg effect. Increased tumor growth and metastasis have also been …

Until now, observations regarding the central morphology and organization of Ia, group II and Ib Golgi tendon organ afferents have been confined to the cat model. As the use of rodents in the study of the development and organization of segmental spinal cord circuitry increases, a complete account of the peripheral encoding and central connectivity of rodent muscle proprioceptors is necessary. The data presented in this study establish the central morphology and spatial distribution of 12 (4 of each class) functionally phenotyped muscle proprioceptor afferents in the rat by intracellular labeling with Neurobiotin. Each afferent type showed a characteristic central …

There is currently no direct evidence that chemotherapy induced peripheral neuropathy (CIPN) necessarily explains the sensorimotor deficits seen in 90% patients treated with oxaliplatin (OX). Some patients develop sensory symptoms without CIPN. Our laboratory reported abnormal signaling from IA afferents in OX treated rats with no evidence of neuropathy. We hypothesized that in the absence of CIPN, the behavioral disability is associated with impaired sensory encoding in OX treated rats. The purpose of this study was to investigate the sensorimotor abilities of OX treated rats. The battery of behavioral tests was designed to address proprioception and sensorimotor integration. In the …
