AIM: To evaluate a novel grading system to predict lymph node metastasis (LNM) in patients with submucosal invasive colorectal carcinoma (SICRC). METHODS: We analyzed the associations between LNM and various clinicopathological features in 252 patients with SICRC who had undergone radical surgery at the Seoul Saint Mary's hospital between 2000 and 2015. RESULTS: LNM was observed in 31 patients (12.3%). The depth and width of the submucosal invasion, lymphatic invasion, tumor budding, and the presence of poorly differentiated clusters (PDCs) were significantly associated with the incidence of LNM...

Matrix metalloproteinases (MMPs) constitute a large group of endoproteases that play important functions during embryonic development, tumor metastasis and angiogenesis by degrading components of the extracellular matrix. Within this family, we focused our study on Mt4-mmp (also called Mmp17) that belongs to a distinct subset that is anchored to the cell surface via a glycosylphosphatidylinositol (GPI) moiety and with the catalytic site exposed to the extracellular space. Information about its function and substrates is very limited to date, and little has been reported on its role in the developing embryo...

Since its discovery in 1979, p53 has been on the forefront of cancer research. It is considered a master gene of cancer suppression and is found mutated in around 50% of all human tumors. In addition, the progressive identification of p53-related transcription factors p63 and p73 as well as their multiple isoforms have added further layers of complexity to an already dense network. Among the numerous models used to unravel the p53 family mysteries, S. cerevisiae has been particularly useful. This seemingly naive model allows the expression of a functional human p53 and thus the assessment of p53 intrinsic transcriptional activity...

Ribosomal RNAs (rRNAs) in budding yeast are encoded by ~100-200 repeats of a 9.1kb sequence arranged in tandem on chromosome XII, the ribosomal DNA (rDNA) locus. Copy number of rDNA repeat units in eukaryotic cells is maintained far in excess of the requirement for ribosome biogenesis. Despite the importance of the repeats for both ribosomal and non-ribosomal functions, it is currently not known how "normal" copy number is determined or maintained. To identify essential genes involved in the maintenance of rDNA copy number, we developed a droplet digital PCR based assay to measure rDNA copy number in yeast and used it to screen the yeast conditional temperature-sensitive mutant collection of essential genes...

This project was undertaken to address a critical cancer biology question: Is overexpression of the pluripotency molecule Nanog sufficient to initiate tumor development in a somatic tissue? Nanog1 is critical for the self-renewal and pluripotency of ES cells, and its retrotransposed homolog, NanogP8 is preferentially expressed in somatic cancer cells. Our work has shown that shRNA-mediated knockdown of NanogP8 in prostate, breast, and colon cancer cells inhibits tumor regeneration whereas inducible overexpression of NanogP8 promotes cancer stem cell phenotypes and properties...

Although a secondary mutation and the epithelial-to-mesenchymal transition (EMT) are encountered very often in patients received the EGFR-TKI targeted treatment. The entire detrimental morphological change of the cancer entity was rare reported. Herein we report a case that acquired resistance to EGFR-TKI with T790M mutation and complete EMT morphological change of the tumor tissue. The primary lung tumor from a 52-year-old woman was diagnosed with moderate differentiated adenocarcinoma, with intensively positiveTTF-1 and E-cadherin in differentiated glandular structure but not the budding cancer cell cluster which with an intensive Vimentin staining...

In colorectal carcinoma, poorly differentiated clusters (PDCs) are a poor prognostic indicator and show morphological continuity and behavioral similarities to micropapillary patterns (MPPs) as well as tumor buds (TBs). Epithelial-mesenchymal transition (EMT) and inhibition of cancer-stromal interactions may contribute to the development of PDCs. To clarify the biological nature of PDCs, we examined immunohistochemical stainings for β-catenin, Ki-67, E-cadherin, epithelial cell adhesion molecule (EpCAM), MUC1, and epithelial membrane antigen (EMA), which are associated with EMT and cancer-stromal interactions...

Tumor budding is defined as the presence of a single tumor cell or a small cluster of up to five cells in the tumor stroma, linking it to the epithelial-mesenchymal transition (EMT).(1) Imai(2) illustrated that tumors with this trait have more aggressive qualities and allocated the term "sprouting" instead of "budding." The term "tumor budding" was coined by Morodomi et al in 1989.(3) Tumor budding in vitro or in experiments has been addressed by many names, depending on the researcher's background, few of which are tumor cell dissociation, focal dedifferentia-tion, or EMT...

BACKGROUND: MiRNAs are often deregulated in colorectal cancer and might function as tumor suppressors or as oncogenes. They participate in controlling key signaling pathways involved in proliferation, invasion and apoptosis and may serve as prognostic and predictive markers. In this study we aimed to evaluate the role of miRNA-148a and miRNA-625-3p in metastatic colorectal cancer. METHODS: Fifty-four patients with a first-time diagnosed CRC receiving FOLFOX ± Bevacizumab were involved in the study...

OBJECTIVE: To explore the effect of nano carbon tattooing on the lesion localization in the early colon cancer for additional surgical procedure after endoscopic resection. METHODS: Thirty-five patients with early colon cancer accepted additional surgical procedures after endoscopic resection in Fuzhou General Hospital of PLA from May 2014 to November 2016. All the patients underwent nano carbon tattooing before the end of endoscopic resection: 0.1 ml carbon nanoparticles suspension was respectively injected into the normal intestinal submucosa from 1 cm outside the 4 sites (upper, lower, left and right) of the lesion border by colonoscopy, marking the original lesion location and guiding the subsequent additional surgery...

AIM: To evaluate the maspin expression in colorectal carcinomas (CRC) and its possible role in quantification of the tumor budding. METHODS: The tumor budding was prospectively quantified in 49 consecutive cases of patients that underwent surgical resection for CRC. The cases were divided in two groups: group A (n=23) - low budding (<5 tumor buds per high microscopic field) and group B (n=26) - high budding CRCs (≥5 buds). Maspin expression was evaluated in the tumor core and the buds from the hot spot area in 44 of the microsatellite stable adenocarcinomas...

It is of great clinical importance to identify simple prognostic markers from preoperative biopsies that could guide treatment planning. Here, we compared tumor budding (B), depth of invasion (D), and the combined scores (i.e., budding and depth of invasion (BD) histopathologic model) in preoperative biopsies and the corresponding postoperative specimens of oral tongue squamous cell carcinoma (OTSCC). Tumor budding and depth of invasion were evaluated in the pre- and postoperative samples from 100 patients treated for OTSCC...

Tumor budding is a well-established adverse prognostic factor in colorectal carcinoma (CRC). It may represent a form of epithelial-to-mesenchymal transition (EMT), although the underlying mechanisms remain unclear. High-temperature requirement A3 (HtrA3) is an inhibitor of the bone morphogenetic protein pathway, the suppression of which has been linked to EMT. Since HtrA3 is highly expressed in the desmoplastic stroma at the CRC invasive front, we sought to evaluate the relationship between tumor budding and HtrA3 expression in 172 stage II CRC resection specimens...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

Mammary gland development begins with the appearance of epithelial placodes that invaginate, sprout, and branch to form small arborized trees by birth. The second phase of ductal growth and branching is driven by the highly invasive structures called terminal end buds (TEBs) that form at ductal tips at the onset of puberty. Ectodysplasin (Eda), a tumor necrosis factor-like ligand, is essential for the development of skin appendages including the breast. In mice, Eda regulates mammary placode formation and branching morphogenesis, but the underlying molecular mechanisms are poorly understood...

Increased mTORC1 signaling from TSC1/TSC2 inactivation is found in cancer and causes tuberous sclerosis complex (TSC). The role of mesenchymal-derived cells in TSC tumorigenesis was investigated through disruption of Tsc2 in craniofacial and limb bud mesenchymal progenitors. Tsc2cKO(Prrx1-cre) mice had shortened lifespans and extensive hamartomas containing abnormal tortuous, dilated vessels prominent in the forelimbs. Abnormalities were blocked by the mTORC1 inhibitor sirolimus. A Tsc2/mTORC1 expression signature identified in Tsc2-deficient fibroblasts was also increased in bladder cancers with TSC1/TSC2 mutations in the TCGA database...

Substantial evidence has shown that epithelial-mesenchymal transition (EMT) plays critical roles in colorectal cancer (CRC) development and prognosis. To uncover the pivotal regulators that function in the cooperative interactions between cancer cells and their microenvironment and consequently affect the EMT process, we carried out a systematic analysis and evaluated prognosis in CRC specimens. Tumor buds and their surrounding stroma were captured using laser microdissection. We used gene expression profiling, bioinformatics analysis and regulatory network construction for molecular selection...
