Abstract
Mutations in the transcription factor-coding gene SOX18, the growth factor-coding gene VEGFC and its receptor-coding gene VEGFR3/FLT4 cause primary lymphedema in humans. In mammals, SOX18, together with COUP-TFII/NR2F2, activates the expression of Prox1, a master regulator in lymphatic identity and development. Knockdown studies have also suggested an involvement of Sox18, Coup-tfII/Nr2f2, and Prox1 in zebrafish lymphatic development. Mutants in the corresponding genes initially failed to recapitulate the lymphatic defects observed in morphants. In this paper, we describe a novel zebrafish sox18 mutant allele, sa12315, which behaves as a null. The formation of the lymphatic thoracic duct is affected in sox18 homozygous mutants, but defects are milder in both zygotic and maternal-zygotic sox18 mutants than in sox18 morphants. Remarkably, in sox18 mutants, the expression of the closely related sox7 gene is elevated where lymphatic precursors arise. Sox7 could thus mask the absence of a functional Sox18 protein and account for the mild lymphatic phenotype in sox18 mutants, as shown in mice. Partial knockdown of vegfc exacerbates lymphatic defects in sox18 mutants, making them visible in heterozygotes. Our data thus reinforce the genetic interaction between Sox18 and Vegfc in lymphatic development, previously suggested by knockdown studies, and highlight the ability of Sox7 to compensate for Sox18 lymphatic dysfunction.

Abstract
Primary Ovarian Insufficiency (POI) is a female fertility disorder which affects 1% of women before 40 years of age and manifests with amenorrhea, elevation of serum gonadotrophins and low estrogens. POI has a strong genetic component with incomplete penetrance. Several candidate genes have been described so far, however, its etiopathogenesis is mostly unknown. In order to discover the POI-related causative mechanisms, microarray transcriptome analysis in human granulosa cells (hGCs) stimulated with recombinant human BMP15 (rhBMP15) and next generation sequencing analysis (NGS) on the identified differentially expressed genes in a selected group of patients with POI were conducted on NGS Illumina platform. In the present study, we obtained 19 differentially expressed genes upon rhBMP15 stimulation in hGCs. Results: showed that all identified genes were upregulated and associated to pluripotency, inhibition of apoptosis, cell proliferation, BMP signaling and apoptosis. Moreover, we identified nine POI patients bearing six rare variants in 5 of the BMP15-induced genes (SAMD11, SMAD6, ID1, USP35, GPCR137C). The BMP15-induced transcriptome analysis in hGCs contributed the understanding of BMP15 role as transcriptional regulator, through the activation of transcriptional repressors, by inducing pathways inhibiting the ovarian follicle maturation, thus possibly maintaining an undifferentiated state of hGCs. These findings lead to the identification of novel candidate genes for POI.

Abstract
Primary ovarian insufficiency (POI) is one of the major causes of female infertility associated with the premature loss of ovarian function in about 3.7% of women before the age of 40. This disorder is highly heterogeneous and can manifest with a wide range of clinical phenotypes, ranging from ovarian dysgenesis and primary amenorrhea to post-pubertal secondary amenorrhea, with elevated serum gonadotropins and hypoestrogenism. The ovarian defect still remains idiopathic in some cases; however, a strong genetic component has been demonstrated by the next-generation sequencing (NGS) approach of familiar and sporadic POI cases. As recent evidence suggested an oligogenic architecture for POI, we developed a target NGS panel with 295 genes including known candidates and novel genetic determinants potentially involved in POI pathogenesis. Sixty-four patients with early onset POI (range: 10-25 years) of our cohort have been screened with 90% of target coverage at 50×. Here, we report 48 analyzed patients with at least one genetic variant (75%) in the selected candidate genes. In particular, we found the following: 11/64 patients (17%) with two variants, 9/64 (14%) with three variants, 9/64 (14%) with four variants, 3/64 (5%) with five variants, and 2/64 (3%) with six variants. The most severe phenotypes were associated with either the major number of variations or a worse prediction in pathogenicity of variants. Bioinformatic gene ontology analysis identified the following major pathways likely affected by gene variants: 1) cell cycle, meiosis, and DNA repair; 2) extracellular matrix remodeling; 3) reproduction; 4) cell metabolism; 5) cell proliferation; 6) calcium homeostasis; 7) NOTCH signaling; 8) signal transduction; 9) WNT signaling; 10) cell death; and 11) ubiquitin modifications. Consistently, the identified pathways have been described in other studies dissecting the mechanisms of folliculogenesis in animal models of altered fertility. In conclusion, our results contribute to define POI as an oligogenic disease and suggest novel candidates to be investigated in patients with POI.

Abstract
Mucolipidosis type IV (MLIV) is an autosomal recessive lysosomal storage disorder caused by mutations in the MCOLN1 gene coding for mucolipin-1 (TRPML1). TRPML1 belongs to a transient receptor potential channels (TRP) subfamily, which in mammals includes two other members: mucolipin-2 (TRPML2) and mucolipin-3 (TRPML3). Bioinformatic analysis of the Danio rerio (zebrafish) genome and trascriptome revealed the presence of five different genes related to human mucolipins: mcoln1.1, mcoln1.2, mcoln2, mcoln3.1 and mcoln3.2. We focused our efforts on the characterization of the two putative zebrafish MCOLN1 co-orthologs. Transient-expression experiments in human HeLa cells demonstrated that fish Mcoln1.1 and Mcoln1.2, similarly to TRPML1, localize to late endosomal/lysosomal compartments. Real-Time PCR (RT-PCR) experiments showed that both genes are maternally expressed and transcribed at different levels during embryogenesis. RT-PCR analysis in different zebrafish tissues displayed ubiquitary expression for mcoln1.1 and a more tissue-specific pattern for mcoln1.2. Spatial and temporal expression studies using whole-mount in situ hybridization confirmed that both genes are maternally expressed and ubiquitously transcribed during gastrulation and early somitogenesis. Notably, in the next developmental stages they are more expressed in neural regions and in retina layers, tissues affected in MLIV. Interestingly, mcoln1.1 is detected, from 10 somite-stage until to 36 hpf, in the yolk syncytial layer (YSL) and in the intermediate cell mass (ICM), the earliest site of hematopoiesis. Overall, the redundancy of mucolipins together with their expression profile support the biological relevance of this class of proteins in zebrafish. The data herein presented indicate that Danio rerio could be a suitable vertebrate model for the study of some aspects of MLIV pathogenesis.

Abstract
Despite their importance as members of the Roundabout (Robo) family in the control of axonal and vascular patterning, the transcriptional regulation of these genes is poorly understood. In this study, we show that members of the Sry-related high mobility box (Sox) transcription factor family as being transcriptional regulators of roundabout4 (robo4), a Robo gene family member that participates in sprouting angiogenesis in vivo, in zebrafish. Double whole mount in situ hybridization analysis in zebrafish embryos revealed co-localization of the vascular relevant Sox factors sox7 or sox18 mRNA with robo4 transcripts in developing intersomitic vessels. A 3-kb human ROBO4 promoter element was able to drive reporter expression in zebrafish to recapitulate the endogenous temporal intersomitic vessel expression pattern of robo4. EMSA analysis confirmed binding of Sox18 to a canonical Sox binding site (from -1170 bp to -1176 bp) in the ROBO4 promoter (3 kb), and mutation analysis indicated that this site was partially responsible for ROBO4 promoter activity in ECs. A combination of gain- and loss-of-function analysis identified Sox7 and Sox18 co-regulation of robo4 but not fli1a transcripts in zebrafish. Finally, Sox-mediated robo4 transcriptional regulation is conserved across evolution. These studies imply Sox-mediated transcriptional regulation of Robo4 in the developing embryonic vasculature.

Abstract
The High-Mobility Group Box (HMGB) proteins are highly abundant proteins with both nuclear and extracellular roles in key biological processes. In mammals, three family members are present: HMGB1, HMGB2 and HMGB3. We characterized the HMGB family in zebrafish and report a detailed phylogenetic analysis of HMGB proteins. The B1, B2, and B3 subfamilies are present in cartilaginous fish, bony fish, and tetrapods, while jawless fish sequences emerge as basal to the gene family expansion. Two co-orthologs of each mammalian HMGB gene are present in zebrafish. All six zebrafish hmgb genes are maternally expressed, but huge differences in expression levels exist during embryonic development. The hmgb2a/hmgb2b genes are the most highly expressed, while hmgb3b is expressed at the lowest level. Remarkably, hmgb3 genes are not present in fugu, medaka, Tetraodon and stickleback. Our analysis highlights substantial overlaps, but also subtle differences and specificities in the expression patterns of the zebrafish hmgb genes.
