We previously demonstrated that tamoxifen (TAM)-resistant human breast cancer (TAMR-MCF-7) cells showed increased expression of mesenchymal marker proteins compared to the parent MCF-7 cells. Notch is functionally important in the promotion of epithelial-mesenchymal transition (EMT) during both development and tumor progression. Notch1 and Notch4 have been reported as prognostic markers in human breast cancer. Here, we indicated that Notch4, but not Notch1, plays a critical role in the regulation of EMT signaling in TAMR-MCF-7 cells...

Pathological response to preoperative chemotherapy was recently found to be correlated with improved survival and has been proposed as a new outcome end-point following resection of liver metastases from colorectal cancer (CRC). It was demonstrated that, particularly after therapy with bevacizumab, CRC liver metastases decreased in size and underwent distinct morphological changes on computed tomography (CT). However, morphological changes in response to treatment with regorafenib have not yet been reported...

Choriocarcinoma is a human chorionic gonadotrophin (HCG)-secreting tumor that comprises vascular channels. It has a tendency for widespread metastasis, common sites for which include the lung, vagina, brain, liver, bone, intestine, and kidney. We describe a 30-year-old female who presented with hepatitis-like features and bilateral diminution of vision, and subsequently developed hemothorax and hemoperitoneum-all rare and seemingly unrelated manifestations which were finally attributable to metastases from gestational choriocarcinoma...

Never in mitosis gene A (NIMA)-related kinase 2 (NEK2) is a microtubule-associated protein that regulates spindle assembly in human cells and is overexpressed in various malignancies. However, the role of NEK2 in hepatocellular carcinoma (HCC) remains undetermined. We performed RNA-seq of the HCC cell line SMMC-7721 and the normal liver cell line HL-7702 using the Ion Proton System. NEK2 expression was detected using quantitative reverse transcription polymerase chain reaction in two cell lines and 5 matched HCC and adjacent non-tumorous liver tissues...

Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. The majority of the patients are Caucasian (97.8%) and aged 50-80 years. Choroidal melanoma is the predominant type (86.3%). The clinical presentation may range from no symptoms over various types of visual disturbances to visual loss. Examination includes slit-lamp biomicroscopy, indirect ophthalmoscopy and diagnostic testing, such as B-scan ultrasonography. A number of patients with posterior UM are treated with plaque radiation therapy or enucleation...

Colorectal cancer is a prevalent malignancy worldwide, and investigations are required to elucidate the underlying carcinogenic mechanisms. Amongst these mechanisms, de novo carcinogenesis and the adenoma to carcinoma sequence, are the most understood. Metastasis of colorectal cancer to the liver often results in fatality, therefore, it is important for any associated risk factors to be identified. Regarding the treatment of the disease, it is important to manage not only the primary colorectal tumor, but also the liver metastases...

BACKGROUND: Solitary fibrous tumours (SFT) are neoplasms of mesenchymal origin that predominantly arise from the pleura. SFT of the liver (SFTL) are a rare occurrence with little number of cases reported in English literature. Malignant cases of hepatic SFT are an even rarer occurrence. For this reason, the prognostic evaluation of SFTLs is unknown and difficult to measure. METHODS: A search on English literature on "Solitary Fibrous Tumour of the Liver" was conducted on common search engines (PubMed, Google)...

Liver resection is still the most commonly used therapeutic option for hepatocellular carcinoma (HCC) at present, and liver regeneration promotes HCC growth in the regenerating liver. The higher recurrence/metastasis of HCC is the main cause of death for HCC patients after liver resection. However, it remains unclear how to abolish the augmented growth and metastasis of the possible residual HCC induced by the promoted liver regeneration after liver resection. In this study, a rat model with liver cirrhosis and diffused HCC was established by Diethylnitrosamine administration, recombinant miR-203 adenovirus was administered to induce hepatic miR-203 overexpression and 30% partial hepatectomy (PH) was followed, then the effect of miR-203 on the proliferation, invasion and metastasis of the residual HCC in the remnant cirrhotic liver with promoted regeneration was investigated...

Talin-1 is a known oncogene-associated protein. In this study, we set out to determine its role and mechanisms in hepatocellular carcinoma (HCC) progression. We found Talin-1 to be highly expressed in HCC cells relative to non-cancer liver epithelial cells and to promote tumor growth and metastasis. We used Whole Human Genome Oligo Microarray analysis with HCC cells and HCC cells in which Talin-1 was knocked down using shRNA to identify transcripts regulated by Talin-1. Of the 40,000 tested genes, 3099 were differentially expressed after Talin-1 knockdown; expression of 1924 genes was increased, while expression of 2175 was decreased...

Nearly one-third of all melanoma patients will experience disease recurrence and the majority of the relapses eventually develop metastatic disease as a consequence of disease progression in the early-stage melanoma patients. Although the factors that predict the recurrence have already been described, very few numbers of studies have investigated the natural recurrence history of melanoma. In this retrospective study, we analyzed the time until recurrence along with the patterns and outcomes of the recurrences; thus, we aimed to understand the possible factors that might influence the recurrence course in early-stage cutaneous melanoma at the first relapse...
