An ultrasensitive sandwich-type electrochemical immunosensor was developed for quantitative monitoring of Alpha fetoprotein (AFP). To achieve this objective, an incorporated signal amplification strategy of platinum nanoparticles anchored on cobalt oxide/graphene nanosheets (Pt NPs/Co3O4/graphene) was proposed by acting as the label of secondary antibodies. The prepared label not only empowered by advantages of each component but exhibited better electrochemical performance than single Pt NPs, Co3O4 and graphene, which has shown large specific surface area and good catalytic activity towards the reduction of H2O2...

BACKGROUND: Alpha-fetoprotein (AFP) and Glypican 3 (GPC3) are both oncogenes and reactivated in hepatocellular carcinoma (HCC). PreS2 has been proved to be an important transactivator in HCC. In this study, we aim to provide evidence that HBV protein preS2 is responsible for AFP and GPC3's reactivation in HCC. METHODS: Totally Sixty-three cases of HCC, aged 34-79, who were surgically treated and pathologically confirmed were enrolled. The levels of AFP in peripheral serum were detected with electrochemical luminescence method before surgery...

BACKGROUND: Preoperative serum inflammatory markers have been correlated with outcome after resection of hepatocellular carcinoma (HCC), but studies have had conflicting results. This study aimed to evaluate the association of six inflammatory markers with recurrence-free survival (RFS), overall survival (OS), and microvascular invasion (MVI), a well-known prognostic factor. METHODS: This study investigated 370 patients who underwent resection of HCC from 1992 to 2016, retrospectively evaluating their inflammatory indices and individual components including their neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), prognostic nutritional index (PNI), aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase-to-neutrophil ratio index (ANRI)...

Hepatocellular carcinoma (HCC) is a highly lethal malignant tumor evolved from cirrhosis. It is quite significant to seek accurate, easy markers for early warning and diagnosis of HCC. Through prospective cohort follow-up study and mass spectrometry, we discovered and verified a serum marker valuable for early warning and diagnosis. Follow-up observation was performed on cirrhosis patients. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was adopted to detect the serums of patients, and the serum polypeptides with a potential value in early HCC warning and diagnosis were screened...

AIM: The prognostic significance of the half-lives (HLs) of alpha-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC) is unclear. We evaluated the HLs of AFP and DCP in a cohort of such patients. METHODS: This study included data on 202 patients with HCC who underwent curative hepatectomy and had preoperative AFP concentrations ≥ 100 ng/mL or DCP ≥ 200 mAU/mL. We calculated the HLs of AFP and DCP from their values just before and one month after hepatectomy...

Fifteen novel 1,2,3-triazole derivatives were prepared in series of synthetic steps starting from 4-amino-5-hydrazino-4H-1,2,4-triazole-3-thiol 1. The structures of the obtained compounds were verified through micoanalytical and spectral data. All the compounds were screened for their anticancer activity against liver human cancer cell lines (HEPG2) using Doxorubicin as standard. The most promising triazolothiadiazine derivative 12 was further tested for its degree of toxicity by estimating the median lethal dose (LD 50) and its antitumor activity through inhibiting the angiogenesis and progression of tumor against diethylnitrosamine (DENA)/CCl4 induced hepatocellular carcinoma (HCC) in rats...

We previously demonstrated that the Tg737 gene plays a critical role in the carcinogenesis of hepatocellular carcinoma (HCC). However, few systematic investigations have focused on the biological function of Tg737 in the invasion and migration of liver cancer stem cells (LCSCs) and on its clinical significance. In this study, Tg737 overexpression was achieved via gene transfection in MHCC97-H side population (SP) cells, which are considered a model for LCSCs in scientific studies. Tg737 overexpression significantly inhibited the invasion and migration of SP cells in an extracellular signal-regulated kinase1/2 (ERK1/2)/matrix metalloproteinase-2 (MMP-2)-dependent manner...

Hepatic resection (HR) and radiofrequency ablation (RFA) are popular local therapies for early-stage hepatocellular carcinoma (HCC). Alpha-fetoprotein, Lens culinaris agglutinin-reactive fraction of alpha-fetoprotein, and des-c-carboxy prothrombin are well-known and useful tumor markers for HCC. The positive number status of these tumor markers has recently been demonstrated as beneficial for predicting outcome for HCC patients treated with local therapy. Although the normal ranges reported have differed by institution, the positivity of tumor markers is consistent and can easily be assessed...

Alpha-fetoprotein is an effective biomarker as an aid in hepatocellular carcinoma detection in many countries. However, alpha-fetoprotein has its limitations, especially in early hepatocellular carcinoma diagnosis. Protein induced by vitamin K absence or antagonist-II is another biomarker that is used for hepatocellular carcinoma detection. The aim of this study is to compare the diagnostic performance of alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II alone and in combination to explore improving biomarker performance as an aid in early hepatocellular carcinoma detection...

Alpha-fetoprotein (AFP)-L3 was originally reported as a hepatocellular carcinoma (HCC)-specific tumor marker, and recent accumulation of evidence has revealed that AFP-L3 frequency predicts the biological malignancy potential of HCC. However, AFP-L3 elevation from undetectable levels after curative treatment could not be discussed due to the difficulties of calculating AFP-L3 concentrations when serum AFP levels were low. Here, as a novel method, we used highly sensitive AFP-L3 frequency to predict HCC recurrence after curative treatment...

OBJECTIVE: Prothrombin induced by the absence of vitamin K or antagonist-II (PIVKA-II) is a useful tumor marker for hepatocellular carcinoma (HCC). However, the usefulness of post-transplantation surveillance with PIVKA-II is not clear. We evaluated the clinical value of PIVKA-II in monitoring HCC recurrence after living-donor liver transplantation (LDLT). METHODS: One hundred twenty patients who had undergone LDLT for HCC from February 1999 to December 2010 and whose serum alpha-fetoprotein (AFP) and PIVKA-II had been measured sequentially before and after LDLT were included in this study...

Ovarian Sertoli-Leydig cell tumors (SLCTs) are uncommon neoplasms that are occasionally associated with an elevated level of serum alpha fetoprotein (AFP), a marker of germ cell neoplasms, particularly yolk sac tumor (YST). We report 7 cases of ovarian SLCT (3 moderately differentiated, 2 poorly differentiated, 2 retiform) with heterologous intestinal-type glands, 6 of which were associated with elevated serum AFP. The intestinal-type mucinous glands were immunoreactive for SALL4 (4 cases), AFP (4 cases), glypican 3 (1 case), CDX2 (6 cases), and villin (7 cases), markers that are commonly expressed in YSTs, although the latter 2 markers would be expected to be positive in intestinal-type glands...
