Abstract
PURPOSE Brain-derived neurotrophic factor (BDNF) belongs to the family of neurotrophic factors that can potentially increase cancer cell growth, survival, proliferation, anoikis, and migration by tyrosine kinase receptors TrkB and the p75NTR death receptor. The activation of BDNF/TrkB pathways leads to several downstream signaling pathways, including PI3K/Akt, Jak/STAT, PLCγ, Ras-Raf-MEK-ERK, NF-kB, and transactivation of EGFR. The current review aimed to provide an overview of the role of BDNF and its signaling in cancer. METHODS We searched a major medical database, PubMed, to identify eligible studies for a narrative synthesis. RESULTS Pathological examinations demonstrate BDNF overexpression in human cancer, notably involving the prostate, lung, breast, and underlying tissues, associated with a higher death rate and poor prognosis. Therefore, measurement of BDNF, either for identifying the disease or predicting response to therapy, can be helpful in cancer patients. Expression profiling studies have recognized the role of microRNAs (miR) in modulating BDNF/TrkB pathways, such as miR-101, miR-107, miR-134, miR-147, miR-191, miR-200a/c, miR-204, miR-206, miR-210, miR-214, miR-382, miR-496, miR-497, miR-744, and miR-10a-5p, providing a potential biological mechanism by which targeted therapies may correlate with decreased BDNF expression in cancers. Clinical studies investigating the use of agents targeting BDNF receptors and related signaling pathways and interfering with the related oncogenic effect, including Entrectinib, Larotrectinib, Cabozantinib, Repotrectinib, Lestaurtinib, and Selitrectinib, are in progress. CONCLUSION The aberrant signaling of BDNF is implicated in various cancers. Well-designed clinical trials are needed to clarify the BDNF role in cancer progression and target it as a therapeutic method.

Abstract
Brain-derived neurotrophic factor (BDNF) is involved in regulating the growth of ovarian follicles, maturation of the oocyte, and development of the early embryo through its receptor, tyrosine kinase receptor B (TrkB). However, it is still unclear as to how BDNF influences proliferation and steroidogenesis of bovine granulosa cells (GCs). In this paper, we confirmed that BDNF and TrkB were expressed in bovine GCs, and that proliferation and steroidogenesis by bovine GCs were reduced by knockdown of BDNF or inhibition of TrkB. With respect to GC proliferation, BDNF enhanced cellular viability and the percentage of cells in the S phase. BDNF also activated both protein kinase B (PKB, also known as AKT) and the extracellular signal-regulated protein kinase 1/2 (ERK1/2)-signaling pathway. Through the AKT-signaling pathway, BDNF increased the expression of proliferation-related genes, including cyclin A1 (CCNA1), cyclin E2 (CCNE2), cyclin D1 (CCND1), and cyclin-dependent kinase 1 (CDK1). However, through the ERK1/2 signaling pathway, BDNF only increased the expression of CCNA1 and CCNE2. Regarding steroidogenesis by bovine GCs, BDNF promoted progesterone (P 4 ) synthesis, but had no effect on estradiol; it also activated the AKT-signaling pathway and increased the expression of steroidogenesis-related genes, including steroidogenic acute regulatory protein (STAR) and hydroxy-δ-5-steroid dehydrogenase, 3β- and steroid δ-isomerase 1 (HSD3B1). In summary, our data are the first to show that BDNF promotes the proliferation of bovine GCs through TrkB-AKT and ERK1/2 signaling pathways and increases P4 synthesis by bovine GCs through the TrkB-AKT signaling pathway.

Abstract
Zebrafish, a suitable and widely used teleost fish model in basic biomedical research, displays morphophysiological features of adult gonads that share some commonalities with those of mammalian species. In mammals, gametogenesis is regulated, among several factors, by brain-derived neurotrophic factor (BDNF). This neurotrophin has a well-established role in the developing and adult nervous system, as well as gonads development and functions in vertebrate species. We hypothesize that BDNF has a role also in the gonadal functions of zebrafish. At this purpose, we investigated BDNF and its receptors p75 and TrkB in the ovary and testis of adult zebrafish, kept under laboratory conditions. Our results display (1) the expression of BDNF mRNA and pro-BDNF protein outside of the nervous system, specifically in the ovary and testis; (2) the presence of pro-BDNF in primary oocytes and follicular layer, and p75 in follicular cells; (3) the localization of pro-BDNF in type B spermatogonia, and Sertoli cells in testis. Altogether, these data lead us to consider that BDNF is involved in the gonadal function of adult zebrafish, and mainly in the adult ovary. Anat Rec, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
It is reported recently Tropomyosin-related receptor Kinase B (TrkB) plays key roles in the anoikis resistance during the processes of tumorigenesis and metastasis. However, its prognostic significance for clinical patients remains inconclusive. In order to establish a correct and practicable link between increased TrkB and prognostication of human solid tumors, a meta-analysis was performed in this article. A systematic literature research in the electronic databases PubMed, Embase and Web of Science was performed to identify eligible studies. A fixed-effects meta-analytical model was employed to correlate TrkB expression with OS, DFS and clinicopathological features. A total of 11 studies covering 1516 patients with various solid tumors were recruited in this meta-analysis. TrkB over-expression was associated with poorer OS and poorer DFS in multivariate analysis. Additionally, the pooled odds ratios (ORs) indicated that TrkB over-expression was associated with large tumor size, lymph node metastasis, distant metastasis and a higher clinical stage. Overall, these results indicated that TrkB over-expression in patients with solid tumors might be related to poor prognosis and serve as a potential predictive marker of poor clinicopathological prognosis factor.

Abstract
The neurotrophin family of proteins and their receptors act as important proliferative and pro-survival factors in differentiation of nerve cells and are thought to play key roles in the development of reproductive tissues and normal function of spermatozoa. The objective of the present study was to evaluate the effect of Brain-Derived Neurotrophic Factor (BDNF) on the sperm viability and motility, lipid peroxidation (LPO), mitochondrial activity and concentration of leptin, nitric oxide (NO) and insulin in normozoospermic men. Semen samples from 20 normozoospermic men were divided into three groups: (i) control, (ii) BDNF and (iii) BDNF + K252a. BDNF and K252a were added in the dose of 0.133 and 0.1 nM, respectively. Viability was assessed by eosin-nigrosin staining technique, and motility was observed by microscopy. NO concentration and mitochondrial activity were measured with flow cytometry, and LPO was analyzed using enzyme-linked immunosorbent assay (ELISA) kits. Results showed that exogenous BDNF at 0.133 nM could significantly (p < 0.05) influence viability, motility, NO concentration, mitochondrial activity and LPO content. Secretions of insulin and leptin by human sperm were increased in cells exposed to the exogenous BDNF, whereas viability, mitochondrial activity and insulin and leptin secretions were decreased in cells exposed to the K252.

Abstract
Sperm is highly differentiated cell that can be easily obtained and purified. Mature sperm is considered to be transcriptionally and translationally silent and incapable of protein synthesis. Recently, a large number of proteins have been identified in sperm from different species by using the proteomic approaches. Clinically, sperm proteins can be used as markers for male infertility due to different protein profiles identified in sperm from fertile and infertile male animals. Recent evidences have shown that the conditions of sperm preservation in vitro can also change the sperm protein profiles. This paper reviews the recent scientific publications available to address sperm proteome and their relationship with sperm cryopreservation, capacitation, fertilization, and separation of X and Y sperm. Future directions in the application of sperm proteomics to develop or optimize reproductive technologies in mammals are also discussed.

Abstract
Neurotrophins are a family of polypeptide growth factors that are required for the proliferation, differentiation, survival, and death of neuronal cells. A growing body of evidence suggests that they may have broader physiological roles in various non-neuronal tissues. The testicles are complex non-neuronal organs in which diverse cell types interact to achieve correct spermatogenesis. Both neurotrophins and their receptors have been detected in various cell types from mammalian testes, suggesting that neurotrophins may regulate or mediate intercellular communication within this organ. This review summarizes the existing data on the cellular distribution and possible biological roles of neurotrophins in the testes. The data reported in the literature indicate that neurotrophins affect somatic cell growth and spermatogenesis and imply that they play a role in regulating testicular development and male reproduction.

Abstract
The presence of a complex population of gene transcripts in mature human sperm is well established, and numerous mRNAs and non-coding mRNAs have been identified in sperm of men and other mammalian species using microarray and RT-PCR. The traditional concept that RNAs in mature sperm are only remnants from spermatogenesis and have no biological functions is in doubt. The findings that reverse transcriptases in sperm are active and that sperm can independently activate translation of stored mRNAs suggest that sperm RNAs may have significant effects on male fertility. The differences in expression profiles among RNAs in mature sperm from fertile and infertile men, and the regulation of sperm RNAs in embryonic development make them appealing markers for therapeutic and diagnostic tools in male infertility. In this review, methods for the detection and description of the diversity of gene transcript in sperm are discussed along with their putative roles in functional aspects of sperm and in embryogenesis.
