Chen Z, Liu M, Hu JH, Gao Y, Deng C, Jiang MH. Substance P restores spermatogenesis in busulfan-treated mice: A new strategy for male infertility therapy. Biomed Pharmacother 2021; 133:110868. [PMID: 33181455 DOI: 10.1016/j.biopha.2020.110868] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 10/06/2020] [Accepted: 10/07/2020] [Indexed: 01/15/2023] Open
Abstract
Male infertility has become an important health problem that is primarily caused by testicular dysfunction with abnormal spermatogenesis. In this study, we demonstrated that the neuropeptide, substance P (SP), is essential for spermatogonia proliferation in a seminiferous tubule culture system. In addition, SP (5 nmol/kg) treatment markedly restored spermatogenesis, improved sperm quality, and increased the number of ZBTB16+ or LIN28+ undifferentiated spermatogonia as well as STRA8+ differentiated spermatogonia in a busulfan-induced non-obstructive azoospermic mouse model. Furthermore, 100 nM SP treatment in vitro significantly stimulated the proliferation of GC-1 spg cells (a spermatogonia cell line) via activation of the Erk1/2 signaling pathway. Moreover, the sperm quality and the number of spermatogonia were significantly reduced after treatment with RP67580, a selective NK-1 receptor antagonist, suggesting that SP-NK1R signaling plays an important role in spermatogenesis. Taken together, these results suggest that SP may be a potential therapeutic agent for male infertility by accelerating the restoration of spermatogenesis.

Abstract
Changes in cell metabolism are an important feature of tumors that has always been an intense topic of study, particularly in regard to whether metabolic disorders are a cause or an effect of tumorigenesis. Studies have shown that the processes underlying metabolic changes in tumors involve the activation of protooncogenes and the inactivation of cancer suppressor genes, as well as changes in metabolic flux in cells due to the abnormal activation of signaling pathways that modulate metabolic enzymes and/or metabolic regulatory proteins at several levels, including transfer and posttranslational modification. Thus, the repair of abnormal metabolic pathways via intervention in the relevant tumor metabolic pathways that impact specific targets has become a new method of cancer prevention and treatment. Bioactive peptides, which have many biological functions, could specifically target malignant tumors. Their interaction with signal transduction molecules involved in the development and transference of tumors could regulate the relevant cell metabolic pathways and inhibit the development of tumors and/or accelerate apoptosis in tumor cells. In this review, several aspects of tumor suppression using bioactive peptides will be discussed and summarized, including the regulation of the PI3K/AKT/mTOR, AMPK, and STST3 signaling pathways, the modulation of the TRAIL death receptor signaling pathway, the regulation of aerobic glycolysis by PKM2, and the modulation of the NF-кB signaling pathway, to aid in the search for better and more specific antineoplastic drugs in the form of bioactive peptides.

[PMID: 30455626 PMCID: PMC6230717 DOI: 10.3389/fnins.2018.00806] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2018] [Accepted: 10/16/2018] [Indexed: 01/23/2023] Open
Abstract
Purpose: The pancreas is innervated by sensory nerves, parasympathetic and sympathetic nerves. The classical neurotransmitters, acetylcholine and noradrenaline, and some kind of neuropeptides are contained in the terminals of these nerves. Neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) co-released from the primary sensory fibers have been identified as the key neurotransmitters in pancreas. Pancreatic ductal epithelium cells are one of the important sources of the pancreatic islet β-cell neogenesis. We hypothesized that SP and CGRP might play a role on proliferation of ductal cells and differentiation of ductal cells toward the β-cell neogenesis. Methods: Primary ductal cells of rat pancreas at the third passage (P3) were used. The identification of P3 cells were confirmed with flow cytometry analysis and immunostaining by CK19 (the ductal cell marker). Proliferation of ductal cells was verified by CCK-8 assay and Ki67 immunostaining. Differentiation of ductal cells was determined with immunostaining and flow cytometry. Possible mechanism was explored by testing the key proteins of Wnt signaling using Western blot analysis. Results: Our data showed that SP but not CGRP promoted proliferation of ductal cells. Moreover, NK-1 receptor antagonist L-703,606 blocked the SP-induced stimulation of proliferation. The results of Western blot analysis showed that L-703,606 attenuated the effects of substance P on NK1R, GSK-3β, and β-catenin expression. However, SP did not directly induce the differentiation of ductal cells into β-cells, and did not promote the progression of ductal cells to differentiate into more insulin-produced cells in induction medium. Conclusions: These findings suggested that SP but not CGRP promoted proliferation of adult pancreatic ductal cells. SP promoted proliferation of ductal cells but not differentiation into β-cells. NK1R and Wnt signaling pathway might be involved in the mechanism of promoting the proliferation of ductal cells by SP. Findings in this study indicated the lack of SP might be a possible indicator for the initial of diabetes. SP could also be used as a drug candidate for the treatment of diabetes.

Abstract
Periodontitis is a chronic oral inflammatory disease caused by microorganisms. Human β-defensin-3 (HBD-3) is an endogenous antimicrobial peptide that inhibits a broad spectrum of microorganisms. Cell sheet technology has been widely applied in tissue and organ reconstructions. In the current study, it was aimed to investigate the anti-inflammatory effect of periodontal tissue engineered by HBD-3 gene-modified periodontal ligament cell (PDLC) sheets, and to identify a suitable method of promoting the regeneration of periodontal tissues. Western blot analysis and antimicrobial tests were used to confirm the expression of HBD-3. The effect of the cell sheets on anti-inflammatory activity and bone remodeling in a dog model of periodontitis was demonstrated by immunohistochemistry. The results demonstrated that the transfected PDLCs stably expressed HBD-3. Periodontal pathogens were susceptible to the antimicrobial activity of the cell sheets. In addition, the cell sheets relieved the bone resorption caused by inflammation in the in vivo model. HBD-3 may potentially be applied in the treatment of periodontitis and may function as osteogenic promoter via its anti-inflammatory effect.

Abstract
Tachykinins are a large group of neuropeptides with both central and peripheral activity. Despite the increasing number of studies reporting a growth supportive effect of tachykinin peptides in various in vitro stem cell systems, it remains unclear whether these findings are applicable in vivo. To determine how neurokinin-1 receptor (NK-1R) deficient hematopoietic stem cells would behave in a normal in vivo environment, we tested their reconstitution efficiency using competitive bone marrow repopulation assays. We show here that bone marrow taken from NK-1R deficient mice (Tacr1(-/-)) showed lineage specific B and T cell engraftment deficits compared to wild-type competitor bone marrow cells, providing evidence for an involvement of NK-1R signalling in adult hematopoiesis. Tachykinin knockout mice lacking the peptides SP and/or HK-1 (Tac1 (-/-), Tac4 (-/-) and Tac1 (-/-)/Tac4 (-/-) mice) repopulated a lethally irradiated wild-type host with similar efficiency as competing wild-type bone marrow. The difference between peptide and receptor deficient mice indicates a paracrine and/or endocrine mechanism of action rather than autocrine signalling, as tachykinin peptides are supplied by the host environment.

Abstract
Over 20.000 umblical cord blood transplantations (UCBT) have been carried out around the world. Indeed, UCBT represents an attractive source of donor hematopoietic stem cells (HSCs) and, offer interesting features (e.g., lower graft-versus-host disease) compared to bone marrow transplantation (BMT). Thereby, UCBT often represents the unique curative option against several blood diseases. Recent advances in the field of UCBT, consisted to develop strategies to expand umbilical stem cells and shorter the timing of their engraftment, subsequently enhancing their availability for enhanced efficacy of transplantation into indicated patients with malignant diseases (e.g., leukemia) or non-malignant diseases (e.g., thalassemia major). Several studies showed that the expansion and homing of UCBSCs depends on specific biological factors and cell types (e.g., cytokines, neuropeptides, co-culture with stromal cells). In this review, we extensively present the advantages and disadvantages of current hematopoietic stem cell transplantations (HSCTs), compared to UBCT. We further describe the importance of cord blood content and obstetric factors on cord blood selection, and report the recent approaches that can be undertook to improve cord blood stem cell expansion as well as engraftment. Eventually, we provide two majors examples underlining the importance of UCBT as a potential cure for blood diseases.

Abstract
AIMS Optimization of transduction condition is an important goal to improve gene transduction. Therefore, we aimed to assess the effect of SP and/or CGRP as novel growth/transducing factors on the efficacy of CD34(+) transduction. METHODS CD34(+) cells were transduced with Gibbon-Ape-Leukemia virus (GALV), containing Neomycin gene. CD34(+) cells were transduced with GALV presence of SP and/or CGRP. Real Time PCR and colony formation assay (CFU-C) was performed. RESULTS Viral vectors titration on Hela cells indicated transduction efficiency of 1×10(6)CFU/ml. Real Time PCR of Neo and CFU-C showed stimulatory role of SP on gene transfer 5.9% and 14.84% compared to 3.6% and 12.58% in control group, while opposite role observed for CGRP 0.89% and 7.86%. Both SP and CGRP showed no significant effect in these assays. DISCUSSION This study showed including of SP in growth factor cocktail is beneficial for CD34(+) transduction, which could be applied to genetic modification procedures.

Abstract
BACKGROUND Modulation of the expression of CXCR4 as a critical adhesion molecule on cord blood (CB) CD34+ cells could overcome delay following cord blood transplantation. Identification of beneficial effects of growth factors including cytokines and neuropeptides on CXCR4 expression would enable our understanding of this complicated network. Therefore, we aimed to assess the role of substance P (SP) and Calcitonin gene related peptide (CGRP) on CXCR4 levels. MATERIAL AND METHODS CD34+cells purified from CB were cultured in a serum-free liquid culture system. Different concentrations of SP and CGRP were used in combination with cytokine cocktail. Expression of CXCR4 at protein and genomic levels was assessed by flow cytometry and real time RT-PCR. RESULTS Our results indicate increased CXCR4+ CD34+ cells after 7 days cultivation with SP and/or CGRP. Increased gene expression of the CXCR4 molecule was observed at 10(-9) M either SP or CGRP individually, by day 11 as compared to control group. CONCLUSIONS Our study indicates that SP and CGRP induce CXCR4 protein expression in short term culture, and stimulate its expression. Consequently, the increased expression of CXCR4 could improve engraftment of CB CD34+ cells.

Abstract
Modulation of adhesion molecules expression on the surface of cord blood (CB) CD34(+) cells may assist in overcoming the delay in cord blood engraftment. Likewise, utilization of diverse growth factors such as neuropeptides could also be helpful. Therefore, we aimed to assess the role of Substance P (SP) along with a cytokine cocktail on CB CD34(+) adhesion molecule expression. CB CD34(+) cells were cultured in a serum-free media containing different concentrations of SP in combination with a cytokine cocktail (SCF, FL, TPO, IL-3, and IL-6). Expression of adhesion molecules CXCR4, CD44, CD49e, and CD62L was analyzed after 7 and/or 11 days of cell cultivation. Additionally, the colonogenic capacity of cells was analyzed by colony formation unit assay. Our results show an enhanced percentage of CD34(+)cells with CXCR4, CD44, and CD62L on day 7, as compared with control. Furthermore, an increase in frequency was observed for CD49e(+) CD34(+)cells by day 7 in both test and control groups compared with day 0. Colonogenic assays show occurrence of more total colony formation and immature progenitor cells in SP-treated cells. Our study indicates that SP could act as an effective modulator for expression of cell adhesion molecules.
