Abstract
MSX1 (Muscle Segment Homeobox 1) has pleiotropic effects in various tissues, including cardiomyocytes, while the effect of MSX1 on cardiomyocyte cellular function was not well known. In this study, we used AC16 cell culture, real-time fluorescence quantitative PCR (qPCR), protein blotting (Western blot), flow cytometry apoptosis assay and lactate dehydrogenase (LDH) ELISA (Enzyme-Linked Immunosorbnent Assay) to investigate the effect of the MSX1 gene on cardiomyocyte function. The results showed that MSX1 plays a protective role against hypoxia of cardiomyocytes. However, further studies are required to fully understand the role of MSX1 in the regulation of LDH expression in different cell types and under different conditions.

Abstract
Degenerative bone disorders have a significant impact on global health, and regeneration of articular cartilage remains a challenge. Existing cell therapies using mesenchymal stromal cells (MSCs) have shown limited efficacy, highlighting the necessity for alternative stem cell sources. Here, we have identified and characterized MSX1+ mesenchymal progenitor cells in the developing limb bud with remarkable osteochondral-regenerative and microenvironment-adaptive capabilities. Single-cell sequencing further revealed the presence of two major cell compositions within the MSX1+ cells, where a distinct PDGFRAlow subset retained the strongest osteochondral competency and could efficiently regenerate articular cartilage in vivo. Furthermore, a strategy was developed to generate MSX1+PDGFRAlow limb mesenchyme-like (LML) cells from human pluripotent stem cells that closely resembled their mouse counterparts, which were bipotential in vitro and could directly regenerate damaged cartilage in a mouse injury model. Together, our results indicated that MSX1+PDGFRAlow LML cells might be a prominent stem cell source for human cartilage regeneration.

Abstract
OBJECTIVE The purpose of this study was to investigate the contribution of MSX1 gene polymorphisms to the risk of developing NSCLP. DESIGN Case-Control Study. SETTING A tertiary care centre. PATIENTS/PARTICIPANTS The sample consisted of 200 subjects (100 cases and 100 controls). INTERVENTIONS None. MAIN OUTCOME MEASURE(S) Genotyping was performed by restriction fragment length polymorphism. Allele and genotype frequencies were calculated between patients and controls and analyzed using online Web Tools such as SISA and SNPstats. The MSX1 gene polymorphisms c. 799 GT, c.458 CA can be risk factors in the development of orofacial clefts. RESULTS In the cases, an association was found between NSCLP and c.799 and c.458 of the MSX1 gene when compared with the control. The dominant and overdominant models, c. 799 GT, c.458 CA genotypes and c. 799 T, c.458 A alleles in the population are said to be the main risk factors to develop the NSCLP in our study population. The genotype variation of c 799 G/T and c.458 C/A are revealed to be specifically contributing to an NSCLP-type Cleft lip and Palate. It is worth noting that NSCLP females in the study population showed a stronger association with heterozygous genotypes of c.799 and c.458. However, further investigation with a larger cohort is necessary to confirm these findings. CONCLUSION Overall the results of the study revealed that MSX1 c 799 G > T and c.458 C > A can be considered as one of the genetic risk factors in the formation of Non-Syndromic Cleft Lip and Palate in the study population.

Abstract
In recent research, there has been a growing awareness of the role of genetic factors in the positioning and eruption of teeth in the maxilla and mandible. This study aimed to evaluate the potential of specific polymorphic markers of single nucleotide polymorphisms (SNPs) located within the PAX9, MSX1, AXIN2, and IRF6 genes to determine the predisposition to tooth impaction. The study participants were divided into two groups: the first group consisted of individuals with at least one impacted secondary tooth. In contrast, the second group (control group) had no impacted teeth in their jaws. To analyze the genes, real-time PCR (polymerase chain reaction) and TaqMan probes were utilized to detect the selected polymorphisms. The findings suggest that disruptions in the structure and function of the mentioned genetic factors such as polymorphic and haplotype variants of PAX9, MSX1, AXIN2, and IRF6 genes, which play a direct role in tooth and periodontal tissue development, might be significant factors in tooth impaction in individuals with genetic variations. Therefore, it is reasonable to hypothesize that tooth impaction may be influenced, at least in part, by the presence of specific genetic markers, including different allelic variants of the PAX9, AXIN2, and IRF6 genes, and especially MSX1.

Abstract
OBJECTIVES This study investigated the association of MSX1 gene variants rs3821949 and rs12532 with nonsyndromic cleft lip and/or palate (NSCL/P) in the Pakistani population. DESIGN Comparative cross-sectional study.Setting: Multicenter of CL/P malformation.Patients/Participants: Unrelated Non-Syndromic cleft Lip/Palate patients and healthy controls were enrolled. METHODS One hundred (n = 100) subjects with NSCL/P and n = 50 unrelated healthy controls were enrolled in a multicenter comparative cross-sectional study. A tetra amplification refractory mutation system (ARMS) polymerase chain reaction (PCR) was performed to analyze MSXI gene single nucleotide variants (SNVs). RESULTS Among 100 NSCL/P subjects, the majority were males (56%; male: female = 1.27: 1). Most of the cases (74%) had cleft lip and palate (CLP) compared to isolated clefts. Genotyping of MSX1 gene variant rs3821949 showed an increased risk for NSCL/P in various genetic models (P < 0.0001), and the A allele exhibited a more than 4-fold increased risk among cases (OR = 4.22: 95% CI = 2.16-8.22; P < 0.0001). Our investigation found no significant difference between the rs12532 variation and NSCL/P. CONCLUSION Our study findings suggest that MSX1 gene variants may increase predisposition to NSCL/P in the Pakistani population. Further studies comprising large samples are required to identify the genetic aetiology of NSCL/P among our people.

Abstract
MSX1 is an important member of the muscle segment homeobox gene (Msh) family and acts as a transcription factor to regulate tissue plasticity, yet its role in goat endometrium remodeling remains elusive. In this study, an immunohistochemical analysis showed that MSX1 was mainly expressed in the luminal and glandular epithelium of goat uterus, and the MSX1 expression was upregulated in pregnancy at days 15 and 18 compared with pregnancy at day 5. In order to explore its function, goat endometrial epithelial cells (gEECs) were treated with 17 β-estrogen (E2), progesterone (P4), and/or interferon-tau (IFNτ), which were used to mimic the physiological environment of early pregnancy. The results showed that MSX1 was significantly upregulated with E2- and P4-alone treatment, or their combined treatment, and IFNτ further enhanced its expression. The spheroid attachment and PGE2/PGF2α ratio were downregulated by the suppression of MSX1. The combination of E2, P4, and IFNτ treatment induced the plasma membrane transformation (PMT) of gEECs, which mainly showed the upregulation of N-cadherin (CDH2) and concomitant downregulation of the polarity-related genes (ZO-1, α-PKC, Par3, Lgl2, and SCRIB). The knockdown of MSX1 partly hindered the PMT induced by E2, P4, and IFNτ treatment, while the upregulation of CDH2 and the downregulation of the partly polarity-related genes were significantly enhanced when MSX1 was overexpressed. Moreover, MSX1 regulated the CDH2 expression by activating the endoplasmic reticulum (ER) stress-mediated unfolded protein response (UPR) pathway. Collectively, these results suggest that MSX1 was involved in the PMT of the gEECs through the ER stress-mediated UPR pathway, which affects endometrial adhesion and secretion function.

Abstract
PURPOSE The goal of this study was to assess genes known to be associated with tooth agenesis with next-generation sequencing (NGS) and analyze the relationship between these mutations and tooth agenesis phenotypes. METHODS The study included 49 individuals aged between 6 and 13 years. A total of 14 genes related to nonsyndromic tooth agenesis were selected for targeted NGS. Mutations in Msh homeobox 1 (MSX1), Wnt family member 10A (WNT10A), axis inhibition protein 2 (AXIN2), keratin 17 (KRT17), lipoprotein receptor 6 (LRP6), and secreted protein, acidic and rich in cysteine (SPARC)-related modular calcium-binding protein 2 (SMOC2) genes were investigated. RESULTS Mutations in six genes were detected in 12 of 49 subjects. Fifteen variants were identified, including the unknown variants c.657G > C in MSX1, c.2029C > T in AXIN2, and c.1603A > T in LRP6. Second premolar tooth agenesis was observed in 43.3% of all tooth agenesis cases with mutations, and it was the predominant phenotype observed for each mutated gene, followed by tooth agenesis of the lateral incisors (20%). CONCLUSIONS Variations in MSX1, WNT10A, AXIN2, KRT17, LRP6, and SMOC2 may be a risk factor for hypodontia or oligodontia in the Turkish population.

Abstract
The expression pattern of the markers p19, Ki-67, MSX1, MSX2, PDL1, pRB, and CYCLINA2 was quantitatively and semiquantitatively analyzed in histologic sections of the developing and postnatal human eye at week 8, in retinoblastoma, and in various uveal melanomas post hoc studies by double immunofluorescence. The p19 immunoreactivity characterized retinal and/or choroidal cells in healthy and tumor tissues: expression was lower in the postnatal retina than in the developing retina and retinoblastoma, whereas it was high in epithelioid melanomas. Ki67 expression was high in the developing eye, retinoblastoma, and choroidal melanomas. MSX1 and MSX2 expression was similar in the developing eye and retinoblastoma, whereas it was absent in the postnatal eye. Their different expression was evident between epithelioid and myxoid melanomas. Similarly, PDL1 was absent in epithelioid melanomas, whereas it was highly expressed in developing and tumor tissues. Expression of pRB and CYCA2 was characteristic of developing and tumorous eye samples but not of the healthy postnatal eye. The observed expression differences of the analyzed markers correlate with the origin and stage of cell differentiation of the tissue samples. The fine balance of expression could play a role in both human eye development and ocular tumorigenesis. Therefore, understanding their relationship and interplay could open new avenues for potential therapeutic interventions and a better understanding of the mechanisms underlying the developmental plasticity of the eye and the development of neoplasms.

Abstract
Background. Hypodontia, or the absence of one or more teeth during tooth formation, is a highly prevalent dental anomaly. Nevertheless, the main causes are still unknown. Mutations in PAX9, MSX1, WNT10A, and AXIN2 genes are most commonly associated with non-syndromic tooth agenesis in the literature. This study investigated these candidate genes in an Iranian family with non-syndromic hypodontia and oligodontia. Methods. Peripheral blood samples of the proband and her family members were collected, and DNA extractions using the salting-out method were carried out. In addition, polymerase chain reaction (PCR) and Sanger sequencing for candidate genes were performed. Results. A missense variant (rs4904210) was identified in the PAX9 gene, with one heterozygous missense variant (rs2240308) and one stop-gained variant (rs121908568) in the AXIN2 gene. Conclusion. By surveying similar studies and analyzing the variant in bioinformatics websites, we concluded that the heterozygous stop-gained variant rs121908568 in exon 8 of the AXIN2 gene could be responsible for tooth agenesis in the Iranian population.

Abstract
Cutaneous melanoma represents one of the deadliest types of skin cancer. The prognosis strongly depends on the disease stage, thus early detection is crucial. New therapies, including BRAF and MEK inhibitors and immunotherapies, have significantly improved the survival of patients in the last decade. However, intrinsic and acquired resistance is still a challenge. In this review, we discuss two major aspects that contribute to the aggressiveness of melanoma, namely, the embryonic origin of melanocytes and melanoma cells and cellular plasticity. First, we summarize the physiological function of epidermal melanocytes and their development from precursor cells that originate from the neural crest (NC). Next, we discuss the concepts of intratumoral heterogeneity, cellular plasticity, and phenotype switching that enable melanoma to adapt to changes in the tumor microenvironment and promote disease progression and drug resistance. Finally, we further dissect the connection of these two aspects by focusing on the transcriptional regulators MSX1, MITF, SOX10, PAX3, and FOXD3. These factors play a key role in NC initiation, NC cell migration, and melanocyte formation, and we discuss how they contribute to cellular plasticity and drug resistance in melanoma.

Abstract
It is known that genetic factors determine odontogenesis; furthermore, studies have revealed that various genes in humans can regulate the development of different types and generations of teeth. In this study it has been assumed that tooth impaction—at least to some extent—also depends on the presence of specific genetic markers, especially allelic variants of the MSX1 gene. The primary objective of the study was to evaluate the suitability of selected molecular markers located within the MSX1 gene for the determination of the risk of tooth impaction in particular patients. The study participants were divided into two groups: (1) the study group—at least one secondary tooth was impacted in the jaws; (2) the control group—no impacted tooth in the jaws. Real-Time PCR and TaqMan probes were used to detect selected polymorphisms in the analyzed genes. Two single nucleotide polymorphisms of MSX1 were analyzed. After the two subgroups of patients were distinguished in the study group based on the number of impacted teeth, statistically significant differences in the frequency of genotypes described for rs12532 in the MSX1 gene were found.

Abstract
Purpose Progestin resistance is a critical obstacle for endometrial conservative therapy. Therefore, studies to acquire a more comprehensive understanding of the mechanisms are urgent. However, the pivotal molecules are still unexplored. Materials and Methods We downloaded GSE121367 from the GEO database. The “limma” R language package was applied to identify differentially expressed genes (DEGs). We conducted Gene Set Enrichment Analysis (GSEA) and Gene Set Variation Analysis (GSVA). Protein–protein interaction was constructed by STRING and visualized in Cytoscape. The tumor immune microenvironment was explored by the TISIDB database. Methylation validation and overall survival analysis were conducted by the TCGA database. In addition, the upstream modulators of hub genes were predicted by miRTarBase and Network Analyst databases. The expression levels of candidate genes were validated by quantitative real-time PCR (qRT-PCR), Western blot, and immunohistochemical assay (IHC). Cell growth, clone formation, migration, invasion, and wound healing assays were studied to explore the role of MSX1 in progestin resistance in vitro. Results A total of 3,282 DEGs were identified and they were mostly enriched in the cell adhesion pathway. We screened out ten hub genes whose genomic alteration rates were low based on the current endometrial carcinoma sample sets. Has-miR-335-5p, has-miR-124-3p, MAZ, and TFDP1 were the most prominent upstream regulators. The methylation status of CDH1, JAG1, EPCAM, and MSX1 was decreased, corresponding to their high protein expression, which also predicted better overall survival. The homeobox protein of MSX1 showed significant tissue specificity and better prognostic value and its knockdown inhibited epithelial–mesenchymal transitions (EMT) and enhanced progesterone efficacy. Conclusion Our study identified that the gene of MSX1 promised to be the specific indicator and therapeutic target for progestin resistance. This would shed new light on the underlying biological mechanism to overcome progestin resistance of endometrial cancer.

Abstract
Prognostic factors are of great interest in patients with endometrial cancer. One potential factor could be the protein MSX1, a transcription repressor, that has an inhibitory effect on the cell cycle. For this study, endometrioid endometrial carcinomas (n = 53), clear cell endometrial carcinomas (n = 6), endometrioid ovarian carcinomas (n = 19), and clear cell ovarian carcinomas (n = 11) were immunochemically stained for the protein MSX1 and evaluated using the immunoreactive score (IRS). A significant stronger expression of MSX1 was found in endometrioid endometrial carcinomas (p < 0.001), in grading 2 (moderate differentiation) (p = 0.001), and in tumor material of patients with no involvement of lymph nodes (p = 0.031). Correlations were found between MSX1 expression and the expression of β-Catenin, p21, p53, and the steroid receptors ERα, ERβ, PRα, and PRβ. A significant (p = 0.023) better survival for patients with an MSX1 expression in more than 10% of the tumor cells was observed for endometrioid endometrial carcinomas (21.3 years median survival (MSX1-positive) versus 17.3 years (MSX1-negative)). Although there is evidence that MSX1 expression correlates with improved long-term survival, further studies are necessary to evaluate if MSX1 can be used as a prognostic marker.

Abstract
An impacted third molar is one of the most common dental abnormalities. Among the reasons for impaction the most common are: insufficient space, time of eruption, improper position of the tooth bud, and genetic disruptions. To investigate if runt-related transcription factor 2 (RUNX2), bone morphogenetic protein 2 (BMP2), and msh homeobox 1 (MSX1) are differently expressed depending on the position of the molar, we studied 32 patients who had been referred for surgical removal. An orthopantomogram was used to separate them according to Winter's, and Pell & Gregory's, classifications. Bone samples were harvested during the operation for gene expression assay. The Kruskal-Wallis, Dunn's post hoc, and Spearman's correlation, tests were used to assess the significance of differences. No correlations were found in expression of the genes, and no differences between expression in maxillary and mandibular third molars, nor were they expressed differently according to Winter's or Pell and Gregory's classifications or in relation to impaction of the mandibular ramus. However, MSX1 was expressed differently when account was taken of the depth of impaction in maxillary third molars (p = 0.029), but there was no difference in expression of RUNX2, BMP2, and MSX1 for the Pell and Gregory classification of depth of impaction (p > 0.05). We conclude that MSX1 is expressed differently depending on the depth of maxillary impaction phenotypes.

Abstract
BACKGROUND Kinesin superfamily (KIFs) has a long-reported significant influence on the initiation, development, and progress of breast cancer. However, the prognostic value of whole family members was poorly done. Our study intends to demonstrate the value of kinesin superfamily members as prognostic biomarkers as well as a therapeutic target of breast cancer. METHODS Comprehensive bioinformatics analyses were done using data from TCGA, GEO, METABRIC, and GTEx. LASSO regression was done to select tumor-related members. Nomogram was constructed to predict the overall survival (OS) of breast cancer patients. Expression profiles were testified by quantitative RT-PCR and immunohistochemistry. Transcription factor, GO and KEGG enrichments were done to explore regulatory mechanism and functions. RESULTS A total of 20 differentially expressed KIFs were identified between breast cancer and normal tissue with 4 (KIF17, KIF26A, KIF7, KIFC3) downregulated and 16 (KIF10, KIF11, KIF14, KIF15, KIF18A, KIF18B, KIF20A, KIF20B, KIF22, KIF23, KIF24, KIF26B, KIF2C, KIF3B, KIF4A, KIFC1) overexpressed. Among which, 11 overexpressed KIFs (KIF10, KIF11, KIF14, KIF15, KIF18A, KIF18B, KIF20A, KIF23, KIF2C, KIF4A, KIFC1) significantly correlated with worse OS, relapse-free survival (RFS) and distant metastasis-free survival (DMFS) of breast cancer. A 6-KIFs-based risk score (KIF10, KIF15, KIF18A, KIF18B, KIF20A, KIF4A) was generated by LASSO regression with a nomogram validated an accurate predictive efficacy. Both mRNA and protein expression of KIFs are experimentally demonstrated upregulated in breast cancer patients. Msh Homeobox 1 (MSX1) was identified as transcription factors of KIFs in breast cancer. GO and KEGG enrichments revealed functions and pathways affected in breast cancer. CONCLUSION Overexpression of tumor-related KIFs correlate with worse outcomes of breast cancer patients and can work as potential prognostic biomarkers.

Abstract
BACKGROUND Tooth agenesis is one of the most common developmental anomalies in human and the main reasons for its occurrence are still unknown. Mutations of several genes such as PAX9, MSX1, AXIN2, KDF1 and WNT10A have been reported which are associated with non-syndromic tooth agenesis. However, PAX9, MSX1 and WNT10A are commonly reported in the literature. Hence, the aim of this study was to investigate the mutations of these genes in 4 Iranian families with non-syndromic tooth agenesis. METHODS DNA extractions from peripheral blood cells of patients with non-syndromic tooth agenesis from 4 unrelated Iranian families were performed by salting out method, and the candidate genes were amplified then followed by Sanger sequencing method. RESULTS One missense variant (rs4904210) and 4 Single Nucleotide Polymorphisms (SNPs) (rs2236007, rs12883298, rs12882923 and rs12883049) were found in PAX9 gene. Five variants (rs149370601, rs8670, rs186861426 and rs774949973) including a missense variant (rs36059701) were detected in MSX1 gene and no variants were found in WNT10A gene. CONCLUSION All variants were analyzed based on bioinformatics websites and Iranian gene databases, and as a result, it was revealed that variants of PAX9, MSX1 and WNT10A may not play a role in non-syndromic tooth agenesis among Iranian cases.

MATERIALS AND METHODS The study is comprised of 384 individuals divided into 4 groups: group 1, patients with unilateral complete NSCLP and premolar agenesis (n = 57); group 2, patients with unilateral NSCLP without tooth agenesis (n = 117); group 3, patients with premolar agenesis without oral cleft (n = 53) and group 4 (n = 157), a control group with individuals without tooth agenesis and oral cleft. Genotyping of rs12532 was carried out with Taqman chemistry, and associations were investigated using logistic regression analyses. RESULTS Overall rs12532 allele and genotype distributions revealed no significant differences between the groups of NSCLP or tooth agenesis. CONCLUSION Although our results are consistent with a lack of association of MSX1 rs12532 and the risk of unilateral NSCLP and tooth agenesis, further studies with additional SNPs and a more diverse ethnic cohort are warranted.

Abstract
Mutations of MSX1 have been associated with nonsyndromic hypodontia. To seek the causal gene mutation sites in a family with nonsyndromic oligodontia, whole-exome sequencing (WES) was performed to seek the causative locus of the family. The candidate mutation was further identified by Sanger sequencing afterward. Two mutations of MSX1 were found both in the proband and her mother. One novel heterozygous missense mutation (c.C667G, p.R223G) of MSX1 inherited from the asymptomatic mother with mosaic mutation was located in the highly conserved fragment of exon 2. The other was a synonymous mutation (c.C348T, p.G116G) in exon 1, which had been reported. The novel maternal heterozygous missense mutation (c.C667G, p.R223G) was likely to be the major reason for nonsyndromic oligodontia in the family. This is the first mosaic variant that has been recorded of the MSX1 gene. Our study expands the phenotype-genotype correlation associated with MSX1 variants. Our study also suggests that the determination of the mosaicism is essential for precise genetic counseling if a disease appears to arise de novo.

Abstract
OBJECTIVE Non-syndromic cleft lip, with or without cleft palate (NSCL/P), is a common craniofacial birth defect, the risk of which is influenced from multiple genetic loci. Association study outcomes between single nucleotide polymorphisms (SNPs) near the muscle segment homeobox gene 1 (MSX1) and NSCL/P have been inconsistent. This compels a meta-analysis to obtain more precise estimates. METHODS From 15 publications, we examined 12 SNPs under six groups (SG), based on linkage disequilibrium. Pooled odds ratios and 95% confidence intervals were calculated under the standard genetic models. The pooled effects were subjected to subgroup, outlier, sensitivity, and funnel plot (publication bias) analyses. RESULTS Three of the six SGs showed significant associations. SG1 and SG4 effects indicated reduced risks. SG1 outcomes were attributed to outlier treatment, which the Asian outcomes validated. In contrast, increased risks were observed in SG3. All these significant outcomes were deemed robust by sensitivity analysis with no evidence of publication bias. CONCLUSIONS Our study shows eight MSX1 SNPs associated with risk of NSCL/P. SG1 and SG4 carriers are protected (up to 23%), but SG3 carriers are 1.3-fold susceptible. Outlier treatment unmasked the significant associations in SG1. Non-heterogeneity and robustness helped elevate the level of evidence in our significant findings.

Abstract
Background Tooth agenesis, one of the most common developmental anomalies, can affect the function and esthetics of patients. The aim of the present study was to identify genetic clues for familial tooth agenesis and explore the underlying mechanisms, focusing on the role of human dental pulp stem cells (hDPSCs). Methods We applied Sanger sequencing to identify the cause of oligodontia in a Chinese family. DNA transfection and functional analysis in DPSCs was also performed to explore the impact of the identified mutation on this phenotype. Results In this study, a novel frameshift mutation, the twenty-nucleotide deletion (c.128_147del20, p.Met43Serfsx125), in exon1 of MSX1 was detected in a Chinese family causing autosomal dominant nonsyndromic oligodontia. The mutation cosegregated with the tooth agenesis phenotype in this family. DPSCs transfected with mutant MSX1 plasmid showed decreased capacity of osteo/odontogenic differentiation with a lower expression level of dentin sialophosphoprotein (DSPP) and bone sialoprotein (BSP) compared with those transfected with control MSX1 plasmid. Mechanically, control MSX1 showed nuclear localization while the mutant MSX1 inhibited its nuclear translocation and localized on the cytoplasm to inhibit ERK phosphorylation. Furthermore, we inhibited the ERK pathway using ERK inhibitor (U0126) treatment in control MSX1-transfected DPSCs which could downregulate mineralized nodule formation and the expression of odontogenic genes. Conclusion We demonstrated a novel MSX1 mutation causing familial nonsyndromic oligodontia and mechanically MSX1 regulates odontogenesis through the ERK signaling pathway in human dental pulp stem cells.

Abstract
PURPOSE The objectives of this study were to investigate the expression of MSX1 in cervical cells and tissues, the methylation status of the MSX1 promoter, the influence of overexpression of gene MSX1 on the proliferation, migration, and invasion of HeLa and SiHa cells, and finally the possible molecular mechanisms responsible for the suppressive effects of MSX1 upon cervical cancer cells. PATIENTS AND METHODS Semi-quantitative and quantitative reverse transcription-polymerase chain reactions were used to investigate the expression levels of MSX1, and methylation-specific polymerase chain reaction (MSP) was performed to investigate promoter methylation status in cervical cancer cell lines, primary cervical tissues, and normal cervical tissues. Clone formation, Cell Counting Kit-8 (CCK-8), cell wound scratch, and transwell assays were performed to verify whether MSX1 could inhibit the proliferation and migration of cervical cancer cells. Western blot was used to analyze the effect of MSX1 upon Notch1, Jagged1, c-Myc, cleaved PARP, cleaved caspse-3, and cyclin D1 (CCND1). RESULTS MSX1 was frequently downregulated or silenced in 60.0% (3/5) of cervical cancer cell lines. The promoter methylation of MSX1 was detected in 42.0% (42/100) of primary tumor tissues, while no methylation was observed in normal cervical tissues. Pharmacological demethylation reduced MSX1 promoter methylation levels and restored the expression of MSX1. The overexpression of MSX1 in cervical cancer cells thus inhibited the proliferation and migration of cervical cancer cells. The overexpression of MSX1 in cervical cancer cells downregulated the expression levels of Notch1, Jagged1, and c-Myc but upregulated the expression levels of CCND1, cleaved PARP, and cleaved caspase-3. CONCLUSION MSX1 appears to be a functional tumor suppressor that regulates tumorigenesis in cervical cancer by antagonizing Notch signaling.

Abstract
The most common outcome of defective dental morphogenesis in human patients is dental agenesis (absence of teeth). This may affect either the primary or permanent dentition and can range from 5 or fewer missing teeth (hypodontia), 6 or more (oligodontia), to complete absence of teeth (anodontia). Both isolated and syndromic dental agenesis have been reported to be associated with a large number of mutated genes. The aim of this review was to analyze the dental phenotypes of syndromic and nonsyndromic dental agenesis linked to gene mutations. A systematic review of the literature focusing on genes ( MSX1, PAX9, AXIN2, PITX2, WNT10A, NEMO, EDA, EDAR, EDARADD, GREMLIN2, LTBP3, LRP6, and SMOC2) known to be involved in dental agenesis was performed and included 101 articles. A meta-analysis was performed using the dental phenotypes of 522 patients. The total number and type of missing teeth were analyzed for each mutated gene. The percentages of missing teeth for each gene were compared to determine correlations between genotypes and phenotypes. Third molar agenesis was included in the clinical phenotype assessment. The findings show that isolated dental agenesis exists as part of a spectrum of syndromes for all the identified genes except PAX9 and that the pattern of dental agenesis can be useful in clinical diagnosis to identify (or narrow) the causative gene mutations. While third molar agenesis was the most frequent type of dental agenesis, affecting 70% of patients, it was described in only 30% of patients with EDA gene mutations. This study shows that the pattern of dental agenesis gives information about the mutated gene and could guide molecular diagnosis for geneticists.

Abstract
OBJECTIVE Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a birth defect for which several genes susceptibility genes been proposed. Consequently, it has been suggested that many of these genes belong to common inter-related pathways during craniofacial development gene-gene interaction. We evaluated the presence of gene-gene interaction for single nucleotide polymorphisms within interferon regulatory factor 6 (IRF6), muscle segment homeobox 1 (MSX1), bone morphogenetic protein 4 (BMP4) and transforming growth factor 3 (TGFB3) genes in NSCL/P risk in Chilean case-parent trios. DESIGN From previous studies, we retrieved genotypes for 13 polymorphic variants within these four genes in 152 case-parent trios. Using the trio package (R) we evaluate the gene-gen interaction in genetic markers pairs applying a 1°-of-freedom test (1df) and a confirmatory 4°-of-freedom (4df) test for epistasis followed by both a permutation test and a Benjamini-Hochberg test for multiple comparisons adjustment. RESULTS We found evidence of gene-gene interaction for rs6446693 (MSX1) and rs2268625 (TGFB3) (4df p = 0.024; permutation p = 0.015, Benjamini-Hochberg p = 0.001). CONCLUSIONS A significant gene-gene interaction was detected for rs6446693 (MSX1) and rs2268625 (TGFB3). This finding is concordant with research in animal models showing that MSX1 and TGFB3 are expressed in common molecular pathways acting in an epistatic manner during maxillofacial development.

Abstract
BACKGROUND Weighted co-expression network analysis (WGCNA) is a powerful systems biology method to describe the correlation of gene expression based on the microarray database, which can be used to facilitate the discovery of therapeutic targets or candidate biomarkers in diseases. OBJECTIVE To explore the key genes in the development of Alzheimer's disease (AD) by using WGCNA. METHODS The whole gene expression data GSE1297 from AD and control human hippocampus was obtained from the GEO database in NCBI. Co-expressed genes were clustered into different modules. Modules of interest were identified through calculating the correlation coefficient between the module and phenotypic traits. GO and pathway enrichment analyses were conducted, and the central players (key hub genes) within the modules of interest were identified through network analysis. The expression of the identified key genes was confirmed in AD transgenic mice through using qRT-PCR. RESULTS Two modules were found to be associated with AD clinical severity, which functioning mainly in mineral absorption, NF-κB signaling, and cGMP-PKG signaling pathways. Through analysis of the two modules, we found that metallothionein (MT), Notch2, MSX1, ADD3, and RAB31 were highly correlated with AD phenotype. Increase in expression of these genes was confirmed in aged AD transgenic mice. CONCLUSION WGCNA analysis can be used to analyze and predict the key genes in AD. MT1, MT2, MSX1, NOTCH2, ADD3, and RAB31 are identified to be the most relevant genes, which may be potential targets for AD therapy.

Abstract
MSX1 is one of the homeoproteins with the homeodomain (HD) sequence, which regulates proliferation and differentiation of mesenchymal cells. In this study, we investigated the nuclear localization signal (NLS) in the MSX1 HD by deletion and amino acid substitution analyses. The web-based tool NLStradamus predicted 2 putative basic motifs in the N- and C-termini of the MSX1 HD. Green fluorescent protein (GFP) chimera studies revealed that NLS1 (161RKHKTNRKPR170) and NLS2 (216NRRAKAKR223) were independently insufficient for robust nuclear localization. However, they can work cooperatively to promote nuclear localization of MSX1, as was shown by the 2 tandem NLS motifs partially restoring functional NLS, leading to a significant nuclear accumulation of the GFP chimera. These results demonstrate a unique NLS motif in MSX1, which consists of an essential single core motif in helix-I, with weak potency, and an auxiliary subdomain in helix-III, which alone does not have nuclear localization potency. Additionally, other peptide sequences, other than predicted 2 motifs in the spacer, may be necessary for complete nuclear localization in MSX1 HD.

Abstract
Before the secretion of hard dental tissues, tooth germs undergo several distinctive stages of development (dental lamina, bud, cap and bell). Every stage is characterized by specific proliferation patterns, which is regulated by various morphogens, growth factors and homeodomain proteins. The role of MSX homeodomain proteins in odontogenesis is rather complex. Expression domains of genes encoding for murine Msx1/2 during development are observed in tissues containing highly proliferative progenitor cells. Arrest of tooth development in Msx knockout mice can be attributed to impaired proliferation of progenitor cells. In Msx1 knockout mice, these progenitor cells start to differentiate prematurely as they strongly express cyclin-dependent kinase inhibitor p19INK4d. p19INK4d induces terminal differentiation of cells by blocking the cell cycle in mitogen-responsive G1 phase. Direct suppression of p19INK4d by Msx1 protein is, therefore, important for maintaining proliferation of progenitor cells at levels required for the normal progression of tooth development. In this study, we examined the expression patterns of MSX1, MSX2 and p19INK4d in human incisor tooth germs during the bud, cap and early bell stages of development. The distribution of expression domains of p19INK4d throughout the investigated period indicates that p19INK4d plays active role during human tooth development. Furthermore, comparison of expression domains of p19INK4d with those of MSX1, MSX2 and proliferation markers Ki67, Cyclin A2 and pRb, indicates that MSX-mediated regulation of proliferation in human tooth germs might not be executed by the mechanism similar to one described in developing tooth germs of wild-type mouse.

Abstract
We report two novel heterozygous missense MSX1 mutations in two Thai families (c.739C>T; p.Pro247Ser and c.607G>A; p.Ala203Thr). The p.Ala203Thr mutation was found in a female patient, her sister, and their father and is associated with unilateral cleft lip and palate, hypodontia, and microdontia. The p.Pro247Ser mutation was found in a three-generation Thai family and was associated with bilateral cleft lip and palate, hypodontia, microdontia, and dens invaginatus. The proband also had preaxial polydactyly of the left hand. The role of Msx1 in limb development in mice is discussed. Intrafamilial variability of the phenotypes is clearly evident. This is the first time that a limb anomaly has been reported to be associated with a mutation in MSX1.

Abstract
OBJECTIVE To determine the association of single-nucleotide polymorphisms (SNPs) in genes related to craniofacial development, which were previously identified as susceptibility signals for nonsyndromic oral clefts, in Brazilians with nonsyndromic cleft lip and/or palate (NSCL/P). DESIGN The SNPs rs748044 (TNP1), rs1106514 (MSX1), rs28372960, rs15251 and rs2569062 (TCOF1), rs7829058 (FGFR1), rs1793949 (COL2A1), rs11653738 (WNT3), and rs242082 (TIMP3) were assessed in a family-based transmission disequilibrium test (TDT) and a structured case-control analysis based on the individual ancestry proportions. SETTING The SNPs were initially analyzed by TDT, and polymorphisms showing a trend toward excess transmission were subsequently studied in an independent case-control sample. PARTICIPANTS The study sample consisted of 189 case-parent trios of nonsyndromic cleft lip with or without cleft palate (NSCL±P), 107 case-parent trios of nonsyndromic cleft palate (NSCP), 318 isolated samples of NSCL±P, 189 isolated samples of NSCP, and 599 healthy controls. MAIN OUTCOME MEASURE Association of alleles with NSCL/P pathogenesis. RESULTS Preferential transmission of SNPs rs28372960 and rs7829058 in NSCL±P trios and rs11653738 in NSCP trios (P = .04) were observed, although the structured case-control analysis did not confirm these associations. The haplotype T-C-C formed by TCOF1 SNPs rs28372960, rs15251, and rs2569062 was more frequently transmitted from healthy parents to NSCL±P offspring, but the P value (P = .01) did not withstand Bonferroni correction for multiple tests. CONCLUSIONS With the modest associations, our results do not support the hypothesis that TNP1, MSX1, TCOF1, FGFR1, COL2A1, WNT3, and TIMP3 variants are risk factors for nonsyndromic oral clefts in the Brazilian population.

Abstract
Glioblastoma is a type of primary brain tumor with poor prognosis. The hallmark phenotype of glioblastoma is its aggressive invasion. Understanding the molecular mechanism of the invasion behavior of glioblastoma is essential for the development of effective treatment of the disease. In our present study, we found that the expression levels of a homeobox transcription factor, MSX1, were significantly reduced in glioblastoma compared to normal brain tissues. The levels of MSX1 in glioblastoma tissues were also correlated with the survival of the patients. In cultured glioblastoma cells, MSX1 was a negative regulator of cell migration and invasion. Loss of MSX1 enhanced cell migration and induced mesenchymal transition as characterized by the downregulation of E-cadherin and the upregulation of N-cadherin. Overexpression of MSX1 on the other hand led to the inhibition of both cell migration and mesenchymal transition. We also found that MSX1 was able to inhibit the Wnt/β-catenin signaling pathway, and that the ability to regulate the Wnt/β-catenin signaling pathway is critical for MSX1 to suppress glioblastoma cell migration and invasion.

Abstract
OBJECTIVE Non-syndromic cleft lip, with or without cleft palate (NSCL/P) is a common craniofacial birth defect, characterised by an incomplete separation between nasal and oral cavities without any other congenital anomaly in humans. Several genes which play a role in cell differentiation, migration, growth and apoptosis, have been associated with clefting. The purpose of this study was to investigate the association between single-nucleotide polymorphisms (SNPs) near MSX1 gene and NSCL/P among South Indian population. METHODS A case-control analysis of five single nucleotide polymorphisms near MSX1 gene (rs11726039, rs868257, rs6446693, rs1907998 and rs6832405) was carried out in 173 patients with NSCL/P and 176 unaffected controls to determine their association with NSCL/P. RESULTS All SNPs were polymorphic in the study population. Comparisons of allele and genotype frequencies revealed that the C variant allele and the TC/CC genotypes of rs11726039 was significantly higher in controls than in the NSCL/P group (OR: 0.63; 95% CI: 0.41-0.097; p=0.037). However, neither of these findings remained significant after Bonferroni correction for multiple comparisons. The frequencies of rs868257, rs6446693, rs1907998 and rs6832405 minor alleles and genotypes were similar between the control and NSCL/P groups. No significant linkage disequilibrium (LD) was observed. Genotype-genotype interaction and the haplotype analysis did not reveal any significant association with NSCL/P. CONCLUSIONS The study results were suggestive of a positive association between MSX1 rs11726039 and NSCL/P in the South Indian population.

Abstract
Oligodontia is congenital absence of one or more teeth which has familial abnormality and attributable to various mutations or polymorphisms of genes often associated with malformative syndromes. The present case reports a rare case of non syndromic oligodontia in an 8-year-old girl with missing 14 permanent teeth excluding third molars in mixed dentition. It is a rare finding which has not been frequently documented in Indian children. Mutations in MSX1 and PAX9 have been described in families in which inherited oligodontia characteristically involves permanent incisors, lateral incisors, premolars and molars. Our study analysed one large family with dominantly inherited oligodontia clinically and genetically. This phonotype is distinct from oligodontia phenotypes associated with mutations in PAX9. Sequencing of the PAX9 revealed a novel mutation in the paired domain of the molecule. The multiple sequence alignment and SNP analysis of the PAX9 exon 2 revealed two mutations.

Abstract
OBJECTIVES In this study, the aim was to investigate a consanguineous Saudi family with non-syndromic premolars and third molars agenesis and to identify the causal mutation(s) using whole exome sequencing. DESIGN Family phenotype and family pedigree were constructed from clinical and radiographic examinations. Whole exome sequencing was performed in two affected members of the Saudi family using the SureSelect Human all Exon 50 Mb kit (Agilent Technologies, Inc., Santa Clara, CA) and then sequenced on an Illumina HiSeq. SNP and indel calling were performed using samtools version 0.18 and were annotated using the software ANNOVAR. RESULTS The family pedigree showed that the inheritance was autosomal dominant. Whole exome sequencing revealed that the affected members in this family were heterozygous with a novel frameshift mutation in exon 2 of the MSX1 gene, (NM_002448:c.750_751insACCGGCTGCC, p.F251PfsX92). CONCLUSIONS The novel MSX1 frameshift mutation was linked to a family with moderate to severe tooth agenesis phenotype affecting second premolars and third molars in both arches. This expands the genotype-phenotype of MSX1 associated conditions.

Abstract
Aim: To search for mutations on the MSX1 gene and to present a genetic basis for non-syndromic tooth agenesis in conjunction with dental anomalies in a Turkish population. Materials and Methods: The patients included in this study were otherwise healthy, with ages ranging from seven to eighteen years. Eighty-two of them had one to six teeth missing (Group I) and 26 had more than six teeth missing (Group II), except for the third molars,. The missing teeth and dental anomalies were examined clinically and radiographically. The MSX1 gene was sequenced from the blood samples of patients who consented to the study. Results: Mutations or polymorphisms on the MSX1 gene were identified in six patients. Taurodontism was seen in patients from both groups I and II. The nucleotide changes were identified by mutation screening. Conclusions: Performing family studies, screening other candidate genes, and investigation of interactions between genes will provide a basis for better analysis of tooth agenesis models and their association with other dental anomalies.

Abstract
An epidemiologic study from the year 2008 found a highly significant increase of congenital tooth agenesis in women with ovarian cancer suggesting that a common genetic etiology may predispose women to both conditions. The finding was reminiscent of a previously described family harboring an AXIN2 mutation which could be shown to segregate with both the tooth agenesis and the predisposition to colon cancer transmitted in this family. Since tooth agenesis as a marker for susceptibility to ovarian cancer would be of great relevance to both oncologists and women with inborn missing teeth, the relationship between the two disorders requires a thorough assessment. We examined DNA samples from the ovarian cancer patients who participated in the original study, to look for a possible genetic connection between their ovarian malignancies and tooth agenesis. MSX1, PAX9, AXIN2, EDA, WNT10A, BARX and BRCA1 genes were selected for sequence analysis as they may cause tooth agenesis, are expressed in the female reproductive system, and/or are involved in tumorigenesis in general or specifically in the ovary. Our study revealed evidence that one half of the dually affected patients had an independent causation of the two conditions, thus reducing the previously estimated ovarian cancer risk for women with congenital tooth agenesis quite significantly.

Abstract
Non syndromic cleft lip and/or palate (NSCLP) is a complex congenital anomaly with varying incidence among patients of different geographical origins. Multiple contributing factors are known to trigger the cleft formation. There are several genes involved in the aetiology of NSCLP and they are different in different populations. The genetic components of clefts that underlie the susceptibility to respond to the environment still remain unclear. In this study, five microsatellite polymorphisms from five candidate genes were employed to analyze the association between these genes and NSCLP in 83 patients and 90 controls. Genotyping was performed by separating and visualizing the fluorescently-labeled polymerase chain reaction (PCR) products. The association of the five microsatellite polymorphisms with NSCLP was tested by using the CLUMP v1.9 program that uses the Monte Carlo method. The genotypic distribution is in Hardy-Weinberg equilibrium in the control group for only the
MSX1
and
DLX3
genes. The
RARA
microsatellite was significantly associated with NSCLP. Our results suggest that the
RARA
gene is involved in pathogenesis of cleft lip and palate in South Indians.

Abstract
OBJECTIVES Oligodontia is defined as the congenital absence of 6 or more permanent teeth excluding the third molar. Tooth agenesis may be classified as syndromic/non-syndromic and as familial/sporadic. To date, more than 300 genes have been found to be involved in tooth development, but only a few of these genes, such as MSX1, PAX9 and AXIN2, are related to the condition of non-syndromic oligodontia. The objective of the present work was to investigate the disease-causing gene of non-syndromic oligodontia in a Han Chinese family and analyse the pathogenesis of mutations that result in oligodontia. DESIGN We examined all individuals of the oligodontia family by clinical and radiographic examinations. Based on the clinical manifestations, the candidate genes MSX, PAX9 and AXIN2 were selected to analyse and screen for mutations. RESULTS The clinical evaluation suggested that the family might show non-syndromic oligodontia. DNA sequencing of the MSX1 gene revealed two mutations in the two patients with oligodontia: a heterozygotic silent mutation, c.348C>T (P.Gly116=), in exon 1 and a homozygotic deletion of 11 nucleotides (c.469+56delins GCCGGGTGGGG) in the intron. However, the silent mutation and the deletion mutation were thought to be known polymorphisms (rs34165410 and rs34341187) by bioinformatics analysis. We did not detect any mutations in the PAX9 and AXIN2 genes of oligodontia patients. CONCLUSION Our finding suggests that identified polymorphisms (c.348C>T and c.469+56delins GCCGGGTGGGG) may be responsible for the oligodontia phenotype in this Chinese family, but the association requires further study.
