Homeobox protein MSX-1 (hereafter referred to as MSX-1) is essential for early tooth-germ development. Tooth-germ development is arrested at bud stage in Msx1 knockout mice, which prompted us to study the functions of MSX-1 beyond this stage. Here, we investigated the roles of MSX-1 during late bell stage. Mesenchymal cells of the mandibular first molar were isolated from mice at embryonic day (E)17.5 and cultured in vitro. We determined the expression levels of β-catenin, bone morphogenetic protein 2 (Bmp2), Bmp4, and lymphoid enhancer-binding factor 1 (Lef1) after knockdown or overexpression of Msx1...

Focal segmental glomerulosclerosis (FSGS) is a pathological lesion rather than a disease, with a diverse etiology. FSGS may result from genetic and non‑genetic factors. FSGS is considered a podocyte disease due to the fact that in the majority of patients with proven‑FSGS, the lesion results from defects in the podocyte structure or function. However, FSGS does not result exclusively from podocyte‑associated genes, however also from other genes including collagen IV‑associated genes. Patients who carry the collagen type IVA3 chain (COL4A3) or COL4A4 mutations usually exhibit Alport Syndrome (AS), thin basement membrane neuropathy or familial hematuria (FH)...

HOX family members encode transcription factors crucial for embryogenesis and may be associated with carcinogenesis. Here, we evaluated the expression of 39 HOX genes in cervical cancer by using clinicopathological information and gene expression data of 308 patients from The Cancer Genome Atlas (TCGA) database. Correlations between mRNA expression of HOX family members and clinicopathological variables were explored. Seventy-three (23.7%) patients died during the follow-up period (median, 22.0 months). Overall mortality was significantly associated with advanced FIGO stage, lymph node metastasis, lymphovascular invasion, and increased HOXA1, HOXA5, HOXA6, and HOXC11 mRNA expression...

Epidemiogical evidence has shown that the incidence of atrial fibrillation in tumor patients is higher than non-tumor patients and general population. The potential risk factors predisposing tumor patients to atrial fibrillation include advanced age, comorbidities, direct anatomic local occupying effect of tumors in the heart or adjacent organs, paraneoplastic manifestations of some tumors, tumor-induced dys-regulation of metabolism, radio-, bio- and chemo-therapeutics, disturbance of autonomous nerve system because of physical pain and psychological sufferings, chronic inflammation typical of most tumors, and surgical interventions among others...

Genital malformations are among the most common human birth defects, and both genetic and environmental factors can contribute to these malformations. Development of the external genitalia in mammals relies on complex signaling networks, and disruption of these signaling pathways can lead to genital defects. Islet-1 (ISL1), a member of the LIM/Homeobox family of transcription factors, has been identified as a major susceptibility gene for classic bladder exstrophy in humans, a common form of the bladder exstrophy-epispadias complex (BEEC), and is implicated in a role in urinary tract development...

Non-syndromic tooth agenesis (NSTA) is the most common developmental anomaly in humans. Several studies have been conducted on dental agenesis and numerous genes have been identified. However, the pathogenic mechanisms responsible for NSTA are not clearly understood. We studied a group of 28 patients with sporadic NSTA and nine patients with a family history of tooth agenesis. We focused on four genes - paired box 9 (PAX9), Wnt family member 10A (WNT10A), msh homeobox 1 (MSX1), and axin 2 (AXIN2) - using direct Sanger sequencing of the exons and intron-exon boundaries...

Corneal endothelial cells (CECs) are essential for maintaining the clarity of the cornea. Because CECs have limited proliferative ability, interest is growing in their potentially therapeutic regeneration from pluripotent stem cells. However, the molecular mechanisms of human CEC differentiation remain largely unknown. To determine the key regulators of CEC characteristics, here we generated a comprehensive promoter-level expression profile of human CECs, using cap analysis of gene expression (CAGE) with a single molecule sequencer...

The development of gastric cancer is significantly associated with chronic inflammation, such as caused by Helicobacter pylori (H. pylori) infection. Caudal-type homeobox 2 (CDX2) is a homeobox protein involved in intestinal differentiation in normal and in aberrant locations, and is associated with inflammation. The authors of the present study have previously reported that CDX2 may have a suppressive role in the progression and carcinogenesis of gastric carcinoma. In the present study, the authors initially confirmed that a decreased expression of CDX2, as detected by immunohistochemistry, is associated with poor cancer-specific survival in 210 gastric cancer cases, which is consistent with several previously published studies...

Interaction between islet cell subtypes and the extracellular matrix influences beta-cell function in mammals. The tissue architecture of rodent islets is very different to that of human islets; cell-to-cell communication and interaction with the extracellular matrix may vary between species. In this work, we have compared the responses of the human EndoC-βH1 cell line to non-human and human-derived growth matrices in terms of growth morphology, gene expression and glucose-stimulated insulin secretion (GSIS)...

B-cell lymphoma 6 (BCL6), a proto-oncogene, is an evolutionarily conserved zinc finger protein that functions as a transcriptional repressor. BCL6 is the master regulator of B-lymphocyte development, and it has been reported that BCL6 may serve an important role in breast cancer progression. The aim of the present study was to investigate the expression of BCL6, zinc finger E-box-binding homeobox (ZEB)1 and ZEB2 and their associations in breast cancer. The mRNA and protein expression of BCL6, ZEB1 and ZEB2 was assessed using in situ hybridization and immunohistochemistry, respectively, in 228 patients with breast cancer and 80 patients with benign breast disease...
