Increased expression of long non-coding RNA CCAT2 predicts poorer prognosis in patients with hepatocellular carcinoma

Background: Long non-coding RNA colon cancer-associated transcript 2 (CCAT2) is a 1752-bp lncRNA transcribed from m8q24 genomic region. A lot of investigations have confirmed the involvement of CCAT2 in the tumorigenesis of many cancer types. Previous studies found that over-expression of CCAT2 significantly promoted cell migration and proliferation, and inhibited apoptosis of HCC cells. In the present investigation, the clinical value and prognostic significance of CCAT2 were investigated. Methods: The 122 pairs of HCC tissues and adjacent normal liver tissues were acquired between September 2013 and February 2018. The expression levels of CCAT2 in HCC tissues and their corresponding adjacent normal liver tissues were examined by RT-qPCR analysis. Survival was calculated using the Kaplan-Meier method and analyzed using the log-rank test. Independent prognostic indicators were determined in the multivariate analysis using Cox's proportional hazard model. Results: CCAT2 expression levels were significantly increased in HCC tissues compared to that in their normal counterparts (P

Authors: Modi A, Dwivedi S, Roy D, Khokhar M, Purohit P, Vishnoi J, Pareek P, Sharma S, Sharma P, Misra S Abstract Growth differentiation factor-15 (GDF-15) is a novel cytokine secreted by a variety of cells like macrophages, adipocytes, normally expressed in high amounts by placenta. It is also highly expressed in multiple carcinomas like Colon, Breast, Pancreas, Liver, and Ovarian. Several reports on serum GDF-15 as a potential biomarker for diagnosis and prognosis of cancer are hampered by the lack of robust data, with large sample size and critical patient recruitment. However, experimental accounts on cancer t...

AbstractWNT2 acts as a pro-angiogenic factor in placental vascularization and increases angiogenesis in liver sinusoidal endothelial cells (ECs) and other ECs. Increased WNT2 expression is detectable in many carcinomas and participates in tumor progression. In human colorectal cancer (CRC), WNT2 is selectively elevated in cancer-associated fibroblasts (CAFs), leading to increased invasion and metastasis. However, if there is a role for WNT2 in colon cancer, angiogenesis was not addressed so far. We demonstrate that WNT2 enhances EC migration/invasion, while it induces canonical WNT signaling in a small subset of cells. Kno...

ín del Valle Polydopamine has acquired great relevance in the field of nanomedicine due to its physicochemical properties. Previously, it has been reported that nanoparticles synthetized from this polymer are able to decrease the viability of breast and colon tumor cells. In addition, it is well known that the size of therapeutic particles plays an essential role in their effect. As a consequence, the influence of this parameter on the cytotoxicity of polydopamine nanoparticles was studied in this work. For this purpose, polydopamine nanoparticles with three different diameters (115, 200 and 420 nm) were synthet...

Hwan Kang While oncolytic vaccinia virus-based therapy has shown promising results for uncured patients with cancer, its effects on cholangiocarcinoma (CCA) remain unclear. Here, we evaluated the anti-cancer activity of the cancer-favoring oncolytic vaccinia virus (CVV), which was recognized as a promising therapy for stem cell-like colon cancer cells (SCCs) and metastatic hepatocellular carcinoma (HCC) in previous studies. CCA presents major challenges, such as clinical complexity, stem cell cancer characteristics, a high refractory rate, resistance to conventional therapy, and a dismal prognosis. In the present study...

ConclusionRCC rarely metastases to the colon but may occur years after curative resection. Therefore, RCC patients should be closely followed for the long term. In case of isolated metastasis, long-term survival can be achieved with R0 resection.

This study was to explore the impact of ropivacaine on the adhesion of tumour cells, providing evidences of its influence on the prognosis of carcinoma.Materials and methodsHuman umbilical vein endothelial cells (HUVECs) were pre-treated with ropivacaine (10–7–10–5 M; 30 min) prior to treatment with tumour necrosis factor alpha (TNF α) (10 ng ml−1; 1, 4 and 8 h). Intercellular adhesion molecule-1 (ICAM-1), endothelial-selectin (CD62E) and vascular cell adhesion molecule-1 (VCAM-1) mRNA levels were detected via quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). To clar...

ConclusionThe results of our series of 13 cases indicate that intraoral soft tissue metastatic carcinomas have a male predilection with a male to female ratio of 11:2, are commonly found in the gingiva and alveolar mucosa (76.9%), present frequently as an easy-bleeding pyogenic granuloma-like lesion (92.3%). In addition, the most common primary cancer site is the liver.
