OBJECTIVE: Recent studies have identified Engrailed-2 (EN-2), a homeobox-containing transcription factor, as a candidate oncogene in prostate cancer (PC). Therapeutic targeting on EN-2, however, is limited because the mechanism underlying EN-2 overexpression in prostatic cancer cells is unknown. This study was to investigate the potential regulatory role of miR-33a on EN-2 expression and explore this signaling axis in ability of prostate cancer survival and metastasis. METHODS: The relative expression of miR-33a and EN-2 in paired prostate cancer tissue and adjacent normal tissue as well as in prostate cancer cell lines, PC3 and DU145, was determined using quantitative real-time PCR or western blot, respectively...

Rho-associated coiled-coil-containing protein kinase 2 (ROCK2) has been known as an effector for the small GTPase Rho and plays an important role in tumor progression and metastasis. However, the effect of ROCK2 in gastric cancer (GC) has not been identified. This study showed that ROCK2 expression significantly increased in clinical GC tissues compared with adjacent non-cancer tissues. Immunohistochemistrical analysis showed that high expression of ROCK2 was correlated with tumor grade, tumor-node-metastasis stage, infiltration depth, lymph node invasion and Ki-67, and predicted poor prognosis in 135 gastric cancer specimens...

Oncogenic BRaf V600E mutation is involved in the development, invasion and metastasis of colon cancer. Selective inhibition of BRaf(V600E) mutant has been recognized as a therapeutic strategy for the cancer. Here, we carried out atomistic molecular dynamics (MD) simulations to characterize the structural basis, energetic property, and dynamics behavior of conformational change in BRaf activation loop upon the mutation. It is found that V600E mutation destabilizes inactive DFG-out conformation of activation loop and promotes its conversion to the active DFG-in conformation, thus conferring constitutive activity for BRaf kinase...

We report a case of adenocarcinoma of the esophagus presenting as an orbital metastasis prior to the primary diagnosis. A 66-year-old white male presented to his ophthalmologist with right orbital swelling for several months. Magnetic resonance imaging revealed a supraorbital infiltrative mass. Pathology from the mass revealed findings consistent with adenocarcinoma of gastrointestinal origin. Upper endoscopy revealed distal esophageal stricture and irregularities. Pathology from the esophagus showed the same malignancy found in the orbit...

Colon cancer metastasis to bone is extremely rare and has devastating consequences on patients' quality of life. Furthermore, radiofrequency ablation in conjunction with cementoplasty to nonweight bearing, flat bones has not been widely reported as palliative treatment for pain as a result of bone metastasis. Here, we present a case of a 47-year-old man who developed a sternal metastasis from an invasive adenocarcinoma of the colon originally diagnosed several years prior. The pain from the metastasis was originally treated with external beam radiation therapy, but after 6 weeks of continuous pain, it was retreated using radiofrequency ablation in conjunction with cementoplasty...

BACKGROUND: Breast cancer is the most common solid tumor to cause cutaneous metastases. These are incurable and the treatment goal is geared toward local control with surgical excision, radiation, and chemotherapy. However, treatment can be challenging in subjects with end-stage liver disease and a multidisciplinary approach is warranted. CASE REPORT: In this case report, we present a 61-year-old female with primary biliary cirrhosis and human epidermal growth factor-2 (HER-2)-positive breast cancer, who subsequently developed cutaneous metastases...

A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease...

INTRODUCTION: Carcinomatous meningitis in breast cancer occurs as a complication in up to 5% of all cases. It is a very devastating diagnosis, with a median patient survival of about 3 months. Treatment is very controversial, and different modalities of treatment have been used but none of them show significant benefit for overall survival. CASE REPORTS: We report 2 cases of carcinomatous meningitis in breast cancer patients. They received a similar treatment of a combination of intrathecal (IT) methotrexate followed by craniospinal radiotherapy...

Primary small-cell carcinoma arising from the bladder (SmCCB) is uncommon. It differs from urothelial carcinoma (UC), the most common type of bladder cancer, with respect to its cell of origin, biology, and prognosis. Biologically, prostatic SmCCB is much more aggressive than UC, and the prognosis for cases with distant metastasis is especially poor. We report here a case of primary SmCCB (cT3bN1M0) treated with radical cystectomy.

BACKGROUND: Chest wall recurrence (CWR) from breast cancer after mastectomy is a difficult to treat disease. Electrochemotherapy (ECT) provides a safe, efficient, and non-invasive locoregional treatment approach in this setting. CASE REPORT: A 61-year-old woman presented with unresectable breast cancer recurrence to the skin and subcutaneous tissue for which numerous lines of treatment were unsuccessful. Between February 2015 and May 2015, the patient underwent 3 courses of ECT after which a spectacular regression of the cutaneous metastatic foci was observed...

Choroidal and skin metastasis of colon cancer is rare. In women, the frequency of cutaneous metastasis from colon cancer as the primary lesion in is 9% and skin metastasis occurs in 0.81% of all colorectal cancers. We report a patient with colonic adenocarcinoma who presented with visual disorder in her right eye and scalp pain as her initial symptoms. Contrast-enhance orbital magnetic resonance imaging with fat suppression revealed an infrabulbar mass, and skin biopsy of the posterior parietal scalp confirmed adenocarcinoma...

Poly (ADP-ribose) polymerase-1 (PARP1) is a highly conserved enzyme focused on the self-repair of cellular DNA damage. Until now, numbers of PARP inhibitors have been reported and used for breast cancer therapy in recent years, especially in TNBC. However, developing a new type PARP inhibitor with distinctive skeleton is alternatively promising strategy for TNBC therapy. In this study, based on co-crystallization studies and pharmacophore-docking-based virtual screening, we discovered a series of dihydrodibenzo[b,e]-oxepin compounds as PARP1 inhibitors...

Lung carcinoma is the leading cause of cancer-related death worldwide, and among this cancer, non-small cell lung carcinoma (NSCLC) comprises the majority of cases. Furthermore, recurrence and metastasis of NSCLC correlate well with CD133+ve tumor cells, a small population of tumor cells, which has been designated as cancer stem cells (CSC). We here for the first time have demonstrated high expression of D2 dopamine (DA) receptors in CD133+ve adenocarcinoma NSCLC cells. Also, activation of D2 DA receptors in these cells significantly inhibited their proliferation, clonogenic ability and invasiveness by suppressing extracellular-signal-regulated kinases 1/2 (ERK1/2) and AKT, downregulation of octamer-binding transcription factor 4 (Oct-4) expression and matrix metalloproteinase-9 (MMP-9) secretion by these cells...

BACKGROUND: Although the survival of patients with cholangiocarcinoma has improved, the prognosis remains unfavorable. The overexpression of mesenchymal-epithelial transition factor (MET) and recepteur d'origine nantais (RON) has been considered to be indicative of a poor prognosis in some types of cancer. On the other hand, some studies have shown that the expression of MET and RON is a favorable prognostic factor in certain types of tumors. MATERIALS AND METHODS: Based on the immunohistochemical analysis of MET and RON, 290 patients who underwent resection for extrahepatic cholangiocarcinoma were divided into three groups: MET/RON-negative, -intermediate, and -positive...

Dysregulation pattern of microRNA-7 (miR-7) and the clinical significance of its expression in colorectal cancer (CRC) are unresolved. Here, we investigated the relationship between clinicopathological factors, including prognostic outcome, and miR-7 expression in CRC tissues. We analyzed miR-7 expression levels by real-time reverse transcription polymerase chain reaction in 210 colorectal tissues (196 CRCs and 14 normal mucosae from healthy volunteers). miR-7 expression levels were significantly up-regulated in CRC tissues compared to normal colorectal mucosae...
