Estudo genômico do tumor embrionário hepatoblastoma

O hepatoblastoma, câncer de fígado mais comum na infância, é um tumor embrionário que se supõe surgir da interrupção da diferenciação hepática durante a embriogênese. O genoma deste tipo tumoral carrega poucas alterações somáticas, principalmente aneuploidias cromossômicas e mutações em...

Retrospective analysis of efficacy, safety, and prognostic factors in a cohort of Chinese hepatocellular carcinoma patients treated with drug-eluting bead transarterial chemoembolization

Braz. j. med. biol. res; 52 (12), 2019
The aim of our study was to assess the efficacy, safety, and prognostic factors of drug-eluting bead transarterial chemoembolization (DEB-TACE) in Chinese hepatocellular carcinoma (HCC) patients. Patients (n=102) diagnosed as primary HCC were consecutively enrolled in this retrospective cohort study. Tre...

Ropivacaine promotes apoptosis of hepatocellular carcinoma cells through damaging mitochondria and activating caspase-3 activity

Biol. Res; 52 (), 2019
BACKGROUND: Recent evidences indicated that some local anaesthetic agents played a role in inhibiting the proliferation of cancer cells; Whether ropivacaine is able to promote apoptosis of hepatocellular carcinoma (HCC) cells is still unclear. The aim of this study was to investigate the effect of ropiva...

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Psoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic prolifer...

HPA-1a/1b could be considered a molecular predictor of poor prognosis in chronic hepatitis C

Abstract INTRODUCTION: HPA polymorphism has been associated with HCV presence and fibrosis progression in chronic hepatitis C. However, it is unknown if there is an association between HPA-1 polymorphism and hepatocellular carcinoma (HCC). Therefore, this study aimed to evaluate HPA-1 polymorphism in t...

lncRNA MEG3 inhibits the growth of hepatocellular carcinoma cells by sponging miR-9-5p to upregulate SOX11

Braz. j. med. biol. res; 52 (10), 2019
The long non-coding RNA (lncRNA) maternally expressed gene 3 (MEG3), a tumor suppressor, is critical for the carcinogenesis and progression of different cancers, including hepatocellular carcinoma (HCC). To date, the roles of lncRNA MEG3 in HCC are not well illustrated. Therefore, this study used western...

Comparison of the prognostic value of platelet-based prognostic models in patients with malignant hepatic tumors after TACE therapy

Acta cir. bras; 34 (7), 2019
Abstract Purpose: To investigate the prognostic value of 17 platelet-based prognostic scores in patients with malignant hepatic tumors after TACE therapy. Methods: In total, 92 patients were divided into death group and survival group according to long-term follow-up results. The AUC was calculated to ...

Sequencing of RAS/RAF pathway genes in primary colorectal cancer and matched liver and lung metastases

Appl. cancer res; 39 (), 2019
Background: Mutations in the RAS/RAF pathway predict resistance to anti-epidermal growth factor receptor antibodies in colorectal cancer (CRC), and may be targets for future therapies. This study investigates concordance of BRAF, HRAS, KRAS, NRAS and PIK3CA mutation status in primary CRC with matched liv...

Impacto do escore MELD na sobrevida de pacientes portadores de carcinoma hepatocelular, transplantados no Brasil: revisão sistemática

Rev. Col. Bras. Cir; 46 (6), 2019
RESUMO O objetivo do estudo foi o de analisar o valor preditivo do escore MELD (Model for End-Stage Liver Disease) na sobrevida de médio e longo prazo em pacientes portadores de carcinoma hepatocelular (CHC), transplantados no Brasil. O estudo foi registrado no PROSPERO (International Prospective Regist...

The long non-coding RNA H19 induces hypoxia/reoxygenation injury by up-regulating autophagy in the hepatoma carcinoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Long non-coding RNA H19 (H19) plays an important role by regulating protein expression in different tissues and organs of the body. However, whether H19 induces hypoxia/reoxygenation (h/R) injury via increase of autophagy in the hepatoma carcinoma cells is unknown. RESULTS: H19 was expressed ...
