Objective: To investigate the effect of binge-like methamphetamine (MA) dosing on brain-derived neurotrophic factor (BDNF) levels and its receptors, trkB and p75NTR.

Summary: The binge-like regimen of MA affects expression of BDNF and its receptors, particularly the trkB receptor, in a time and region dependent manner, and highlights the importance of the frontal cortex and the striatum in the response following MA binge-like dosing.

Objective: To test the hypothesis that A2A receptor antagonism promotes phrenic motor neuron survival and preserves diaphragm function when faced with toxic, neurodegenerative insults that lead to phrenic motor neuron death.

Summary: The authors utilized a novel neurotoxic model of respiratory motor neuron death using intrapleural injections of CTB-SAP. A2A receptors contribute to neurotoxic phrenic motor neuron death, an effect mitigated by A2A receptor antagonism.

Usage: Intrapleural administration of CTB-SAP (25 μg per side) causes: 1) profound phrenic motor neuron death (~5% survival); 2) ~7-fold increase in phrenic motor neuron A2A receptor expression prior to cell death; and 3) diaphragm muscle paralysis (inactive in most rats; ~7% residual diaphragm EMG amplitude during room air breathing).

Objective: To investigate whether there is a molecular mechanism underlying the regulation of LTBP1-TGF-b signaling by the BH4-biosynthesis pathway.

Summary: GTP cyclohydrolase I (GTPCH), 6-pyruvoyltetrahydropterin synthase (PTPS), and sepiapterin reductase (SR) are sequentially responsible for de novo synthesis of tetrahydrobiopterin (BH4), a known cofactor for nitric oxide synthase (NOS). PTPS metabolic activity is required for colorectal tumor cell growth under hypoxia.

Am J Physiol Lung Cell Mol Physiol 318(1):L27-L40. doi: 10.1152/ajplung.00007.2019

Objective: To determine the role of the central chemoreflex in the development of respiratory and autonomic dysfunction in volume overload heart failure (HF).

Summary: Episodic hypercapnic stimulation triggers ventilatory plasticity and elicits cardiorespiratory abnormalities in HF that are largely dependent on retrotrapezoid nucleus (RTN) chemoreceptor neurons.

Usage: Bilateral injections of SSP-SAP, 0.6 ng/30 nL, into the RTN were administered to destroy chemoreceptor neurons.

Objective: To discover the role of brainstem catecholaminergic (CA) neurons in the hypoxic ventilatory response (HVR).

Summary: Brainstem CA neurons modulate the HVR during the postnatal phase, and possibly thermoregulation during hypoxia.

Usage: Evaluation of brainstem CA neurons in the HVR during postnatal development in male and female rats through specific cell depletion with Anti-DBH-SAP (420 ng/nL) injected in the fourth ventricle.

Objective: To determine whether Chlorotoxin-conjugated Saporin (CTX-SAP) would inhibit the growth of aggressive thyroid cancer cell lines expressing MMP-2.

Summary: This in vitro study demonstrated the efficacy of a CTX-SAP conjugate in reducing the viability of ML-1 thyroid cancer cells in a dose dependent manner.

Usage: There was a statistically significant reduction in cell viability with increasing concentrations of the CTX-SAP conjugate (biotinylated Chlorotoxin mixed with Streptavidin-ZAP). The cell viability of ML-1 cells was decreased by 49.77% with the treatment of 600 nM of CTX-SAP (F=44.24). Unconjugated Chlorotoxin or Saporin had no significant effect on cell viability a using similar assay.
