S100A4 promotes liver fibrosis via activation of hepatic stellate cells.
J. Hepatol.
PUBLISHED: 08-08-2014
Show Abstract
Hide Abstract
S100A4 has been linked to fibrosis of several organs as a marker for fibroblasts. However, the role of S100A4 itself in fibrosis development has little been investigated. Herein, we determined whether S100A4 regulates liver fibrogenesis and examined its mechanism by focusing on activation of hepatic stellate cells (HSCs).

Identification of two new HLA-A*0201-restricted cytotoxic T lymphocyte epitopes from colorectal carcinoma-associated antigen PLAC1/CP1.

Hide Abstract
BACKGROUND: To explore the potential application of placenta-specific PLAC1/Cancer Placenta (CP) 1 antigen for immunotherapy in CRC patients, further identification of the cytotoxic T lymphocyte epitopes from this antigen is necessary. METHODS: We assessed the protein expression of PLAC1/CP1 using a tissue chip and immunochemistry staining in CRC samples. Simultaneously, we predicted four PLAC1/CP1-derived HLA-A*0201-restricted peptides by using reverse immunology methods. Peptide-specific CD8(+) T cell responses were assessed by an IFN-? release ELISPOT assay. Effector CD8(+) T cells lyse HLA-A*0201 CRC cell line SW620 was detected in a granzyme-B release ELISPOT cytotoxicity assay. RESULTS: Our results indicated that PLAC1/CP1 was highly expressed in 56.7 % (55/97) of adenocarcinomas. PLAC1/CP1 protein expression was associated with CRC tumor differentiation, the tumor/node/metastasis stage, and lymph node metastasis. Two of four peptides showed high affinities in an HLA-A2 binding assay. In 66.7 % (6/9) of peripheral blood mononuclear cells of CRC samples with PLAC1/CP1 protein-positive expression, these two peptides, PLAC1/CP1 p41-50 (FMLNNDVCV) and PLAC1/CP1 p69-77 (HAYQFTYRV), were immunogenic in the induction of peptide-specific CD8(+) T cell responses as assessed by an IFN-? release ELISPOT assay. Furthermore, the generated effector CD8(+) T cells could specifically lyse the PLAC1/CP1 HLA-A*0201 CRC cell line SW620 in a granzyme-B release ELISPOT cytotoxicity assay. CONCLUSIONS: These results show that the PLAC1/CP1 antigen is a possible prognostic marker of CRC and that PLAC1/CP1 p41-50 and PLAC1/CP1 p69-77 are novel HLA-A*0201-restricted CD8(+) T cell epitopes and potential targets for peptide-based immunotherapy in CRC patients.

FOXP3 gene polymorphism is associated with hepatitis B-related hepatocellular carcinoma in China.
J. Exp. Clin. Cancer Res.
PUBLISHED: 02-06-2013
Show Abstract
Hide Abstract
Previous evidence has shown that the FOXP3 gene was involved in the pathogenesis of several tumors; however, the correlation between single nucleotide polymorphisms (SNPs) in the FOXP3 gene and the susceptibility to hepatitis B-related hepatocellular carcinoma (HCC) remains unclear.

Soil organic carbon and total nitrogen as affected by land use types in karst and non-karst areas of northwest Guangxi, China.
J. Sci. Food Agric.
PUBLISHED: 06-30-2011
Show Abstract
Hide Abstract
Human migration from the karst area to the non-karst area is an important approach for the restoration of degraded karst ecosystems. However, the effects of human-induced land-use change on soil properties are still unclear. The objective of this study was to investigate the effects of land use and parent material on soil organic carbon (SOC) and total nitrogen (TN) at a depth of 0-15 cm in karst and non-karst areas in southwest China.

Ancillary information improves kriging on soil organic carbon data for a typical karst peak cluster depression landscape.
J. Sci. Food Agric.
Show Abstract
Hide Abstract
Soil carbon management at landscape scale requires reliable information on the spatial distribution of soil organic carbon (SOC). However, how to improve the accuracy of spatial prediction is not well addressed in the karst region of southwestern China. This study evaluates the performance of univariate kriging (ordinary kriging (OK)) and hybrid kriging (co-kriging (CK), regression kriging (RK) and residual maximum likelihood (REML)) in mapping the spatial distribution of SOC at a depth of 0-15 cm. Terrain attributes and the normalised difference vegetation index (NDVI) were used as ancillary variables.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
