Cancers (Basel) 11(4):587. doi: 10.3390/cancers11040587 PMID: 31027305

Objective: To investigate the potential of integrin alpha10beta1 as a therapeutic target in glioblastomas (GBMs).

Summary: Integrin alpha10beta1 has a crucial role in the migration, proliferation, and survival of GBM cells and that an integrin alpha10beta1 antibody–drug conjugate induced cell death of GBM cells both in vitro and in vivo.

Usage: Infusions of anti- 10-SAP or Anti-ctrl-SAP were made icv (1 mcg/2 L per infusion).

Objective: To study the ability of a novel bovine serum albumin-angiotensin II (BSA-Ang II) conjugate to effect responses of the AT1 angiotensin II receptor subtype mediated by the G-protein-coupled and the beta-arrestin pathways.

Summary: BSA-Ang II and Ang II stimulated water appetite equivalently but BSA-Ang II stimulated saline appetite more than Ang II. Both BSA-Ang II and Ang II were considerably more potent at causing calcium mobilization than β-arrestin binding.

Usage: Angiotensin II (Ang II) was conjugated with bovine serum albumin and compared with Ang II for competition binding to AT1 receptors, to stimulate aldosterone release from adrenocortical cells, to promote beta-arrestin binding to AT1 receptors, to promote calcium mobilization, and stimulate drinking of water and saline by rats.

Objective: To review the literature describing interconnections between the memory and feeding circuits of the body.

Summary: Gastrointestinal and memory systems within the body are heavily intertwined, something that has been evolutionarily selected for by having to remember food locations, social factors, etc. CCK-SAP (IT-31) has been used to study the connection of gastrointestinal-derived vagal-sensory neurons by selectively lesioning them. These CCK-SAP-treated rats were compared to un-lesioned animals and showed reduced brain-derived neurotrophic factor and memory impairment

Objective: To examine the existence of a neuronal pathway from the hindbrain ependymocytes to kisspeptin neurons in the arcuate nucleus (ARC) and anteroventral periventricular nucleus (AVPV).

Summary: The hindbrain ependymocytes have neuronal connections with the kisspeptin neurons, most probably via hindbrain noradrenergic and CRH neurons to relay low energetic signals for regulation of reproduction.

Objective: To determine the effects of NE depletion on the eCB system.

Summary: The results suggest that the endocannabinoids (eCB) system may be more responsive in males than females under conditions of NE perturbation, thus having potential implications for sex-specific treatment strategies of stress-related psychiatric disorders.

Usage: The authors used a DBH knockout model and DSP-4 (a compound that depletes endogenous norepinephrine and enhances release of [3H]norepinephrine). More specific mechanisms for further corroboration could be undertaken, such as using Anti-DBH-SAP to provide a more complete lesion compared to DSP-4.

Objective: To investigate the contribution of RVLM-C1 neurons on breathing disorders in chronic heart failure (CHF).

Summary: RVLM-C1 neurons play a critical role in the maintenance of altered breathing patterns in CHF rats and highlighted their contribution to the worsening of cardiac function during central chemoreflex activation. DBH-SAP treatment decreased active expiration in CHF rats and deleterious effects of central chemoreflex activation on diastolic cardiac function and cardiac autonomic control were blunted.

Usage: Stereotaxic bilateral injections of Anti-DBH-SAP (5 ng/150 nl).

Objective: The authors explored the role of A2A receptors in phrenic motor neuron cell death in vivo.

Summary: A2A receptors, which contribute to motor neuron death during toxic insults, are upregulated in spared phrenic motor neurons of CTB-SAP treated rats. This is an important finding since A2A receptor upregulation may accelerate motor neuron death in neurodegenerative diseases like ALS.

Usage: CTB-SAP selectively killed nearly all phrenic motor neurons within a week and caused diaphragm paralysis (p<0.01).
