Objective: To identify mutations associated with short-segment Hirschsprung disease (S-HSCR), and use the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 gene editing system to determine how mutations affect enteric neural crest cells (ENCC) function.

Summary: Mutations in vinculin gene (VCL) associated with S-HSCR were identified. Correction of this mutation in iPSC using CRISPR/Cas9 editing, as well as the RET G731del mutation that causes Hirschsprung disease with total colonic aganglionosis, restored ENCC function. The study demonstrates how human iPSCs can be used to identify disease-associated mutations and determine how they affect cell functions and contribute to pathogenesis.

Summary: Although conscious pain experience is driven by signals mediated supraspinally, the more high intensity pain generated by strong stimuli, tissue injury, and nerve injury is encoded at the spinal dorsal horn level. The control of pain signals at the spinal dorsal horn level is a tempting target for targeted pain therapy. This review discusses the potential targets for pain therapeutics in the spinal dorsal horn, and some of the spinal agents used to modulate pain transmission through that location. The use of SSP-SAP (Cat. #IT-11) is mentioned as a neurokinin-1 targeted molecule that can block some pain transmission.

Objective: To determine the functions and targeted suppression of asparaginyl endopeptidase (AEP) in a mouse model of breast cancer-induced bone pain.

Summary: Targeted suppression of AEP with specific small compounds significantly reduced bone pain while purified recombinant AEP proteins increased bone pain. AEP aggravates the development of breast cancer bone metastasis and bone pain by increasing the expression of neurotrophin receptors. AEP might be an effective target for treatment of breast cancer-induced bone pain.

Objective: To analyze the killing potential of TCR-like ADCs.

Summary: Data comprise proof-of-principle results that TCR-like ADCs mediate potent tumor cytotoxicity and support their continued development alongside agents that disrupt DNA replication.  Additionally, TCR-like antibody ligand binding appears to play an important role in ADC functionality and should be addressed during therapy development to avoid binding patterns that negate ADC killing efficacy.

Usage: TCR-like antibodies were indirectly bound to Saporin using Mab-ZAP.  Tumor cells (5×103) were plated in flat-bottom 96-well plates, then Mab-ZAP (100 ng) was added. Various dilutions of isotype control, BB7.2, TCR-like, and 4D5 antibodies were subsequently added to a final volume of 120 mcl and plates were incubated for 3– 5 d at 37 °C with 5% CO2.

Objective: Examine the effects of chronic stress on cognitive status and GR-PKAc-NF-κB signaling in rats with a loss of cholinergic input to the hippocampus and cortex.

Summary: The activation of NF-κB induced by cholinergic depletion appears to be aggravated by chronic stress, and this might explain the increased susceptibility of patients with Alzheimer’s disease to stress since activation of NF-κB is associated with stress.

Objective: To define a novel preclinical measure of movement-induced breakthrough pain (BTP) that is observed in the presence of morphine controlling ongoing pain.

Summary: Novel compounds targeting IB4-binding nociceptors may improve pain management for cancer pain patients and other patient populations suffering from BTP that is inadequately treated by currently available medications.

Usage: To determine the effect of eliminating input from IB4-binding fibers, separate groups of rats received spinal administration of IB4-SAP or the control, Blank-SAP (3.2 mcg/20 mcl saline) followed by a 10 mcl flush of saline. Movement of an air bubble placed between drug solution and saline was used to monitor progress of the injection.

Objective: To isolate nestin-negative outer root sheath cells (ORSCs) from adult healthy volunteers and investigate the neuronal differentiation of these cells.

Summary: The present study did not verify the value of neural differentiation into sphere-forming cells for therapeutic application, however, the differentiation of nestin-negative human hair follicle ORSCs into neurons in vitro may serve as a theoretical underpinning for neurodegenerative diseases and regenerative medicine.

Nat Commun 8:15262. doi: 10.1038/ncomms15262 PMID: 28497782

Objective: To investigate the contribution of Raf genes in tumor progression, from the onset of benign tumors to malignant tumor maintenance, in NRAS-induced mouse melanoma models

Summary: BRAF expression is required for ERK activation and nevi development, demonstrating a critical role in the early stages of NRAS-driven melanoma. After melanoma formation, single BRAF or CRAF ablation is not sufficient to block tumor growth, showing redundant functions for RAF kinases. Proliferation of resistant cells emerging in the absence of BRAF and CRAF remains dependent on ARAF-mediated ERK activation.
