CXCL3 overexpression promotes the tumorigenic potential of uterine cervical cancer cells via the MAPK/ERK pathway.

CXCL3 belongs to the CXC-type chemokine family and is known to play a multifaceted role in various human malignancies. While its clinical significance and mechanisms of action in uterine cervical cancer (UCC) remain unclear. This investigation demonstrated that the UCC cell line HeLa expressed CXCL3, and strong expression of CXCL3 was detected in UCC tissues relative to nontumor tissues.

Overexpression of CXCL3 can enhance the oncogenic potential of prostate cancer.

Purpose: CXCL3 and its receptor CXCR2 were considered to play particularly important roles in the progression of malignancies. However, the investigations about CXCL3/CXCR2 axis in prostate cancer have been poorly involved. Herein we firstly reported our studies on the expression and biological roles of CXCL3 and CXCR2 in prostate cancer.

Necessity of screening water chestnuts for microcystins after cyanobacterial blooms break out.

Water chestnut is one of the most popular vegetables in Asian countries that grows in shallow water. Eighteen water chestnut samples were collected from Lake Tai and six samples were bought at markets in Wuxi, China, in October 2007. Extraction solution of water chestnut was cleaned up with a solid phase extraction column and immunoaffinity chromatography cartridges, then the microcystin (MC) level was detected by indirect competitive enzyme-linked immunosorbent assay (ELISA) and liquid chromatography-mass spectrometry (LC-MS).

Determination of microcystin-LR in water from Lake Tai, China.

Microcystin-LR (MC-LR) is a heptapeptide hepatotoxin produced by cyanobacteria. Immunoaffinity chromatography (IAC) column was prepared with CNBr-activated Sepharose 4B and monoclonal antibody of MC-LR. Water sample was cleaned up by IAC column and the content of MC-LR in water was determined by liquid chromatography-mass spectrometry (LC-MS).

[Production and characterization of gold labeled monoclonal antibody against MC-LR].

Objective: Production of the gold labeled monoclonal antibody against MC-LR. Study the simple mechanism of the conjugation by the spectral analysis.

Methods: Production and purification monoclonal antibodies against MC-LR by hybridoma technology.

[Production purification and characterization of polyantibodies against microcystin-LR].

Objective: Production and characterization the polyantibodies against MCYST-LR.

Methods: microcystin-LR (MC-LR) was conjugated to KLH, then immune the rabbit by the routine method. Purify the antiserum by centrifugal and saturated sulfuric ammonium precipitated methods.

[Preparation and characterization of immunogen against microcystin LR].

Objective: To prepare Microcystins-LR (MC-LR) conjugates with the carrier protein for developing a new immune assay for MC-LR.

Methods: MC-LR was coupled to BSA or KLH by "activated ester" and "water-soluble carbodimide". Measure the combine ratio of MC-LR with KLH or BSA by the UV scanning or the Bradford's method.
