Abstract
Nerve growth factor (NGF) was first discovered approximately 60 years ago by Rita Levi-Montalcini as a protein that induces the growth of nerves. It is now known that NGF is also associated with Alzheimer's disease and intractable pain, and hence, it, along with its high-affinity receptor, tropomyosin receptor kinase (Trk) A, is considered to be 1 of the new targets for therapies being developed to treat these diseases. Anti-NGF antibody and TrkA inhibitors are known drugs that suppress NGF/TrkA signaling, and many drugs of these classes have been developed thus far. Interestingly, local anesthetics also possess TrkA inhibitory effects. This manuscript describes the development of an analgesic that suppresses NGF/TrkA signaling, which is anticipated to be 1 of the new methods to treat intractable pain.

Suppressive effect of membrane-permeable peptides derived from autophosphorylation sites of the IGF-1 receptor on breast cancer cells. Eur J Pharmacol 2015; 765:24-33.

Abstract
Insulin-like growth factor-1 (IGF-1) receptors play a crucial role in the biology of human cancer, making them an attractive target for anti-cancer agents. We previously designed oligopeptides containing the amino-acid sequences surrounding the autophosphorylation sites of the insulin receptor and found that two of them, namely, Ac-DIYET-NH2 and Ac-DYYRK-NH2, suppressed phosphorylation of purified insulin receptors in a non-ATP-competitive manner, whereas Ac-NIYQT-NH2 and Ac-NYYRK-NH2 suppressed in an ATP-competitive manner. Because the IGF-1 receptor is closely related to the insulin receptor, the aim of this study was to observe the effects of these peptides, which correspond to the amino-acid sequences of the autophosphorylation sites of the IGF-1 receptor, on the activity of the human breast cancer cell lines MCF-7, T47D, MDA-MB-231, and MDA-MB-453. To facilitate peptide delivery into breast cancer cells, the cell-penetrating peptide, human immunodeficiency virus type 1-transactivator of transcription (Tat), was linked to these peptides. When breast cancer cells were treated with each of these synthetic Tat-conjugated peptides, the conjugated peptides penetrated into the cells and suppressed cell proliferation. An inhibitory effect of Tat-conjugated peptides against IGF-1-stimulated phosphorylation of IGF-1 receptors was observed. In addition, we found that combinations of these peptides suppressed phosphorylation of IGF-1 receptors to a greater extent than the peptides did individually. In conclusion, IGF-1 receptor autophosphorylation site-derived membrane-permeable peptides have the potential to suppress IGF-1 receptor function in breast cancer cells and to be developed into novel and useful agents for cancer therapy.

Abstract
In an attempt to develop non-ATP-competitive inhibitors of the autophosphorylation of IR, the effects of the synthetic peptides, Ac-DIY(1158)ET-NH(2) and Ac-DY(1162)Y(1163)RK-NH(2), on the phosphorylation of IR were studied in vitro. The peptides were derived from the amino-acid sequence in the activation loop of IR. They inhibited the autophosphorylation of IR to 20.5 and 40.7%, respectively, at 4000 microM. The Asp/Asn- and Glu/Gln-substituted peptides, Ac-NIYQT-NH(2) and Ac-NYYRK-NH(2), more potently inhibited the autophosphorylation than did the corresponding parent peptides. The inhibitory potencies of the substituted peptides were decreased with increasing concentrations of ATP, indicating that these peptides employ an ATP-competitive mechanism in inhibiting the autophosphorylation of IR. In contrast, those of the parent peptides were not affected. Mass spectrometry showed that the parent peptides were phosphorylated by IR, suggesting that they interact with the catalytic loop. Moreover, docking simulations predicted that the substituted peptides would interact with the ATP-binding region of IR, whereas their parent peptides would interact with the catalytic loop of IR. Thus, Ac-DIYET-NH(2) and Ac-DYYRK-NH(2) are expected to be non-ATP-competitive inhibitors. These peptides could contribute to the development of a drug employing a novel mechanism.

Abstract
Although voltage-gated sodium channel (VGSC) activity, upregulated significantly in strongly metastatic human breast cancer cells, has been found to potentiate a variety of in vitro metastatic cell behaviors, the mechanism(s) regulating channel expression/activity is not clear. As a step toward identifying possible serum factors that might be responsible for this, we tested whether medium in which fetal bovine serum (FBS) was substituted with a commercial serum replacement agent (SR-2), comprising insulin and bovine serum albumin, would influence the VGSC-dependent in vitro metastatic cell behaviors. Human breast cancer MDA-MB-231 cells were used as a model. Measurements of lateral motility, transverse migration and adhesion showed consistently that the channel's involvement in metastatic cell behaviors depended on the extracellular biochemical conditions. In normal medium (5% FBS), tetrodotoxin (TTX), a highly specific blocker of VGSCs, suppressed these cellular behaviors, as reported before. In contrast, in SR-2 medium, TTX had opposite effects. However, blocking endogenous insulin/insulin-like growth factor receptor signaling with AG1024 eliminated or reversed the anomalous effects of TTX. Insulin added to serum-free medium increased migration, and TTX increased it further. In conclusion, (1) the biochemical constitution of the extracellular medium had a significant impact upon breast cancer cells' in vitro metastatic behaviors and (2) insulin, in particular, controlled the mode of the functional association between cells' VGSC activity and metastatic machinery.

Abstract
Previously we found that short peptides surrounding major autophosphorylation sites of EGFR (VPEY(1068)INQ, DY(1148)QQD, and ENAEY(1173)LR) suppress phosphorylation of purified EGFR to 30-50% at 4000 microM. In an attempt to improve potencies of the peptides, we modified the sequences by substituting various amino acids for tyrosine or by substituting Gln and Asn for Glu and Asp, respectively. Among the modified peptides, Asp/Asn- and Glu/Gln-substitution in DYQQD (NYQQN) and ENAEYLR (QNAQYLR), respectively, improved inhibitory potencies. The inhibitory potency of NYQQN was not affected by the concentration of ATP, while that of QNAQYLR was affected. Docking simulations showed different mechanisms of inhibition for the peptides: inhibition by binding to the ATP-binding site (QNAQYLR) and inhibition by binding to a region surrounded by alphaC, the activation loop, and the catalytic loop and interfering with the catalytic reaction (NYQQN). The inhibitory potency of NYQQN for insulin receptor drastically decreased, whereas QNAQYLR inhibited autophosphorylation of insulin receptor as well as EGFR. In conclusion, NYQQN is not an ATP-competitive inhibitor and the binding site of this peptide appears to be novel as a tyrosine kinase inhibitor. NYQQN could be a promising seed for the development of anti-cancer drugs having specificity for EGFR.

Abstract
As TrkA, a high-affinity receptor of nerve growth factor (NGF), is a potential target for relieving uncontrolled inflammatory pain, an effective inhibitor of TrkA has been required for pain management. To identify a specific inhibitor of TrkA activity, we designed cell-penetrating peptides combined with amino-acid sequences in the activation loop of TrkA to antagonize tyrosine kinase activity. To select a peptide inhibiting TrkA activity, we examined the effect of cell-penetrating peptides on tyrosine kinase activity of recombinant TrkA in vitro and studied their effects on NGF-stimulated neurite outgrowth and protein phosphorylation in PC12 cells. Thereafter we investigated the effect of the selected peptide on NGF-stimulated TrkA activity and the expression of transient receptor potential channel 1 in PC12 cells. The selected peptide inhibited TrkA activity, but did not inhibit tyrosine kinase activities of other receptor-type tyrosine kinases in vitro. It also suppressed NGF-stimulated responses in PC12 cells. The selected synthetic cell-penetrating peptide antagonizing TrkA function would be a candidate for inflammatory pain therapy.

Abstract
1. Inhibition of uncontrolled epidermal growth factor receptor (EGFR) is one of the approaches for the treatment of breast and lung cancers. We designed oligopeptides consisting of amino-acid sequences of the major (Y1068, Y1148, and Y1173) and minor (Y992) autophosphorylation sites of EGFR. These peptides may be exogenous substrates or pseudosubstrates that interfere with the autophosphorylation of EGFR. The effects of the peptides on autophosphorylation of EGFR were studied. 2. Purified EGFR was phosphorylated in vitro with EGF in the presence of various synthetic peptides. The phosphorylation level of EGFR was then evaluated after SDS-PAGE separation, followed by Western blot analysis with antiphosphotyrosine antibody. 3. Ac-VPEYINQ-NH2 (Y1068) and Ac-DYQQD-NH2 (Y1148) showed the most potent inhibitory effects, followed by Ac-ENAEYLR-NH2 (Y1173). These peptides at 4 mM suppressed phosphorylation to 30-50%. 4. Combination of the three kinds of peptides much more strongly inhibited autophosphorylation. The 50% inhibitory concentration (IC50) value was 0.5 mM as a mixture and was comparable to that of AG1478 (IC50, 0.3 mM) at 0.2 mM ATP. 5. Neither Ac-DIYET-NH2 or Ac-KIYEK-NH2, designed previously based on the amino-acid sequence of an autophosphorylation site of insulin receptor, nor their related (Ac-KIFMK-NH2) or unrelated (Ac-LPFFD-NH2) peptides showed an inhibitory effect. These results suggest that the small peptides that originated from the autophosphorylation sites of EGFR interact solely with EGFR. 6. The peptides containing the sequences surrounding Y1068, Y1148, and Y1173 may be a promising seed for the development of therapeutic agents for breast and lung cancers.

Abstract
Local anesthetics suppress proliferation in several cancer cells. The mechanism of the suppression, however, is unknown. Our previous study shows that lidocaine, at the level of tissue concentration under topical or local administration, has a direct inhibitory effect on the activity of epidermal growth factor receptor (EGFR), which is a potential target for antiproliferation in cancer cells. Therefore, we hypothesized that lidocaine would suppress the proliferation of cancer cells through the inhibition of EGFR activity. We investigated the effects of lidocaine (40-4000 microM) on proliferation of a human tongue cancer cell line, CAL27, which has a high level of EGFR expression, and also examined the effect of lidocaine on epidermal growth factor (EGF)-stimulated autophosphorylation of EGFR in CAL27 cells. A clinical concentration of lidocaine (400 microM) suppressed both serum-induced and EGF-induced proliferation of CAL27 cells and inhibited EGF-stimulated tyrosine kinase activity of EGFR without cytotoxicity. A larger concentration of lidocaine (4000 microM) showed cytotoxicity with an antiproliferative effect. We suggest that the inhibition of EGF-stimulated EGFR activity is one of the mechanisms of the antiproliferative effect of lidocaine on CAL27 cells. Lidocaine administered topically within the oral cavity for cancer pain relief may suppress the proliferation of human tongue cancer cells.

Abstract
Local anesthetics (LAs) suppress sympathetic sprouting, which correlates with neuropathic pain. However, the precise mechanism of the suppression is unknown. Nerve growth factor (NGF) contributes to the sympathetic sprouting, and NGF signaling starts with NGF-stimulated autophosphorylation of TrkA, which is a high affinity receptor of NGF. We examined the effects of lidocaine, bupivacaine, and procaine on NGF signaling under suppression of NGF-stimulated neurite outgrowth in PC12 cells, which is a cellular model of sympathetic sprouting. To investigate the effect of these LAs on NGF-mediated neurite outgrowth of PC12 cells, cells were incubated with 40, 400, and 4000 microM of each LA. The effect of LAs on NGF-stimulated TrkA activity was examined to analyze autophosphorylation of TrkA using immunoprecipitation and immunoblotting. Cytotoxic effects of LAs on PC12 cells were also assessed by lactate dehydrogenase release and by propidium iodide staining. Lidocaine (400 microM), bupivacaine (40 and 400 microM), or procaine (4000 microM) suppressed either neurite outgrowth or autophosphorylation significantly without cytotoxicity. The inhibition of NGF-stimulated tyrosine kinase activity of TrkA might be involved in the mechanisms of suppression of neurite outgrowth induced by LAs.
