Various types of cancer, including melanoma and non-melanoma skin cancer, are associated with vitamin D receptor (VDR) polymorphisms. However, few studies have addressed VDR polymorphisms in patients with mycosis fungoides (MF), and previous studies have reported conflicting results. Aim of this case-control study was to assess the correlation between VDR single nucleotide polymorphisms (SNPs) Cdx2, Fok1, Apa1, Bsm1, and Taq1 and MF. Venous blood samples were collected from 41 patients with MF and 59 age- and sex-matched healthy controls...

POU5F1 is a transcription factor and master regulator of cell pluripotency with indispensable roles in early embryo development and cell lineage specification. The role of embryonic POU5F1 in blastocyst formation and cell lineage specification differs between mammalian species but remains completely unknown in cattle. The CRISPR/Cas9 system was utilized for targeted disruption of the POU5F1 gene by direct injection into zygotes. Disruption of the bovine POU5F1 locus prevented blastocyst formation and was associated with embryonic arrest at the morula stage...

Incomplete epigenetic reprogramming is one of the major factors affecting the development of embryos cloned by somatic cell nuclear transfer (SCNT). Histone 3 lysine 9 (H3K9) trimethylation has been identified as a key barrier to efficient reprogramming by SCNT. The aim of this study was to explore a method of downregulating H3K9me3 levels in donor cells by using histone lysine demethylase (KDM) protein. When sheep fetal fibroblast cells were treated with recombinant human KDM4D protein (rhKDM4D), the levels of H3K9 trimethylation and dimethylation were both significantly decreased...

Two major α-glucosidase (maltase) genes, sucrase-isomaltase (SI) and maltase-glucoamylase (MGAM), respectively, are expressed in the small intestine. In this review, we have summarized whether jejunal expression of these maltase genes is regulated by dietary manipulations, which may affect carbohydrate availability from the luminal side, through changes in the binding of transcription factors and/or histone code on these genes. Studies using a model of mice fed either a low-starch or a high-starch diet for 7 days, found the mRNA levels of SI, MGAM, and Na-glucose cotransporter (SGLT1) genes in the jejunum to be increased in parallel by feeding a high-starch diet...

Identification of the yolk sac tumor (YST) component in germ cell tumors (GCT) may prove challenging, and highly sensitive and specific immunohistochemical markers are still lacking. Preliminary data from the literature suggest that HNF1β may represent a sensitive marker of YST. The specificity of HNF1β has not been addressed in GCT. A cohort of 49 YST specimens from 45 patients was designed, occurring either as pure tumors, or as a component of a mixed GCT. Immunohistochemistry was conducted on whole tumor sections using HNF1β...

Computational analysis and bioinformatics have significantly advanced the ability of researchers to process and analyze biological data. Molecular data from human and model organisms may facilitate drug target validation and identification of biomarkers with increased predictive accuracy. The aim of the present study was to investigate the function of long non-coding RNAs (lncRNAs) in hepatocellular carcinoma (HCC) using online databases, and to predict their regulatory mechanism. HCC-associated lncRNAs, their downstream transcription factors and microRNAs (miRNAs/miRs), as well as the HCC-associated target genes, were identified using online databases...

A 20-membered N2 O2 S2 -macrocycle (L1 ) and a 40-membered N4 O4 S4 -macrocycle (L2 ) were employed as a [1:1] and a [2:2] cyclization product, respectively, for the preparation of diverse types of supramolecular complexes including a cascade complex. Six complexes (1-6) of the smaller macrocycle L1 including discrete to continuous forms, mono- to heteronuclear, and endo- to exo- and endo/exocoordination were prepared and their coordination modes were discussed systemically. First, the reaction of L1 with CuI in the presence of trifluoroacetic acid afforded an exocyclic 1-D coordination polymer {[(μ4 -Cu4 I4 )(HL1 )2 ](CF3 COO)2 } n (1)...

Upregulation of Cdx2 expression in outer cells is a key event responsible for cell lineage segregation between inner cell mass (ICM) and trophoderm (TE) in mouse morula stage embryos. In TE cells, polarization can regulate Hippo and ROCK signaling to induce the nuclear location of YAP, which has been demonstrated to further induce the expression of Cdx2. However, we found that CDX2 expression could not be detected in the outer cells of porcine morula stage embryos and could be found in only some TE cells at the early blastocyst stage...

Mucinous variant of intrahepatic cholangiocarcinoma (iCC) is rare, and its clinicopathological features and prognosis are far less clear. Six patients who had iCCs with more than 50% of mucinous component and 79 conventional iCCs were included in the study. The mean size of mucinous and conventional iCCs was 6.2cm and 6.0cm, respectively. The majority of patients (83%) with mucinous iCC presented at T3 stage or above, compared to 28% of the conventional group (p<0.01). Three patients with mucinous iCC (50%) died within 1year...

Objective: Loss of caudal-type homeobox transcription factor 2 (CDX2) expression in colorectal cancers (CRCs) has recently been proposed as a promising predictive biomarker for not only prognosis but also response to chemotherapy. However, the relationship between alterations in CDX2 expression during cancer progression and response to chemotherapy remains unclear. We herein aimed to determine the concordance of CDX2 expression between primary CRCs and corresponding liver metastases, in association with chemotherapy...

Loss of CDX2 expression has been proposed to be a prognostic biomarker in colorectal cancer (CRC) correlating with shorter overall (OS) and progression-free survival (PFS). Since metastatic disease, mismatch repair (MMR) deficiency, and the mutational status of BRAF are considered to be important prognostic determinants in CRC, the present study aimed to analyze CDX2 expression in correlation with these parameters. Immunohistochemistry for CDX2, hMLH1, and hMSH2 was applied to a study cohort of 503 CRC specimens (FIRE-3) and a matched case-control collection of 50 right-sided CRC specimens with synchronous distant metastases and 50 right-sided CRCs without distant metastases...

Cutaneous metastases from an adenocarcinoma of the Ampulla of Vater are very rare, with only a few cases previously reported. We present here an additional case in a 57-year-old woman who complained of a painful growth on her frontal scalp that she had noticed 4 months earlier. Her medical history included an ampullary adenocarcinoma, which was diagnosed 4 years ago, excised through a Whipple procedure, and treated using chemotherapy and radiotherapy. The scalp biopsy showed a dermal and epidermotropic well-differentiated glandular neoplasm with abundant neutrophils within the luminae of the tumoral glands...

Mesodermal populations can be generated in vitro from mouse embryonic stem cells (mESCs) using three-dimensional (3-D) aggregates called embryoid bodies or two-dimensional (2-D) monolayer culture systems. Here, we investigated whether Brachyury -expressing mesodermal cells generated using 3-D or 2-D culture systems are equivalent, or instead, have different properties. Using a Brachyury -GFP/E2-Crimson reporter mESC line, we isolated Brachyury- GFP+ mesoderm cells using flow-activated cell sorting and compared their gene expression profiles and ex vivo differentiation patterns...

So-called gastric-type adenocarcinoma and related premalignant lesions have been characterized in the cervix, but similar lesions are not widely recognized in the vagina. We report a series of 11 vaginal glandular lesions exhibiting gastric differentiation, comprising 5 cases of adenocarcinoma and 6 of adenosis. All cases occurred in adults (aged 33 to 69) with no known history of diethylstilboestrol exposure. The vaginal adenocarcinomas exhibited morphologic features identical to gastric-type adenocarcinoma of the cervix, but 1 case additionally demonstrated basaloid and sarcomatoid components, which have not been previously reported in cervical gastric-type adenocarcinoma...

The first segregation at the blastocyst stage is the symmetry-breaking event to characterize two cell components; namely, inner cell mass (ICM) and trophectoderm (TE). TEA domain transcription factor 4 (TEAD4) is a well-known regulator to determine TE properties of blastomeres in rodent models. However, the roles of bovine TEAD4 in blastocyst development have been unclear. We here aimed to clarify the mechanisms underlining TE characterization by TEAD4 in bovine blastocysts. We first found that the TEAD4 mRNA expression level was greater in TE than in ICM, which was further supported by TEAD4 immunofluorescent staining...

Distinguishing primary diffuse-type gastric carcinoma (PDGC) versus gastric involvement by metastatic breast carcinoma (mBC), particularly the lobular subtype, is difficult on histology alone. Both can appear morphologically similar. GATA3, a novel transcription factor, is used in certain scenarios as an immunohistochemical marker of breast origin. Our objective was to investigate the efficacy of GATA3 in differentiating PDGC and mBC and how it compares to another breast marker, BRST2. We retrospectively stained 40 cases of PDGC and 10 control cases of mBC from upper gastrointestinal tract specimens for antibodies: GATA3, BRST2, CDX2, and estrogen receptor...

Colorectal cancer (CRC) is the second most frequent and fatal cancer in Western countries. Understanding its biology with different incidence along the colon and rectum, genetic profile and how these factors contribute to local/distant progression, has been hampered by the lack of a suitable CRC model. We report a reproducible model, using human CRC cell lines (CL) (WiDr, LS1034, C2BBe1) injected (1 × 107 cells/animal) in RNU rats (n = 55) which underwent cecostomy and descending colostomy with mucosal-cutaneous fistula of the sigmoid colon...

Pilomatrical (pilomatrix) carcinoma is a rare cutaneous adnexal tumor with matrical differentiation and recurrent and metastatic potential. Sarcomatoid pilomatrix carcinoma is a rare variant which shows a sarcomatoid component intermingling with the epithelial one. There are only four cases previously published. We present an additional case on the hand of a 78 year-old man which appeared as a 6 mm hyperkeratotic ─focally ulcerated─ plaque. A shave biopsy demonstrated a dermal infiltrative neoplasm, composed of markedly atypical-appearing basaloid cells with focal necrotic/ghost cells, as well as an intimately associated population of atypical oval to spindle-shaped cells...
