Therapeutic effects of human monoclonal PSMA antibody-mediated TRIM24 siRNA delivery in PSMA-positive castration-resistant prostate cancer.

: Prostate specific membrane antigen (PSMA) is specifically expressed on prostate epithelial cells and markedly overexpressed in almost all prostate cancers. TRIM24 is also up-regulated from localized prostate cancer to metastatic castration-resistant prostate cancer (CRPC). Because of the high relevance of TRIM24 for cancer development and the universal expression of PSMA in CPRC, we investigated the efficacy of human monoclonal PSMA antibody (PSMAb)-based platform for the targeted TRIM24 siRNA delivery and its therapeutic efficacy in CRPC and .

T-vector and in vivo recombination as tools to construct a large antibody library of breast cancer.

The emergence of phage antibody libraries is an important advance in the field of antibody engineering. It provides a useful methodology to produce human antibodies and has the potential to replace traditional hybridoma technology. In our research, we used T-vector and in vivo recombination to construct a large antibody library from breast cancer patients.

[Expression, purification and activity analysis of human single-chain antibody against hepatocellular cancer].

Aim: To express and characterize an active form of a single-chain antibody (scFv) from the gene of human phage antibodies which is specific for hepatocellular cancer.

Methods: The complementary DNAs encoding the variable regions of the light chain (V(L)) and heavy chain (V(H)) were connected by a (Gly(4)Ser)(3) linker using a splicing by overlap extension polymerase chain reaction. The resultant scFv gene was cloned to the pET28a(+) vector and expressed in E.

[Construction of a large human scFv library against SARS virus].

Aim: To construct a large human scFv library against SARS virus by using in vivo recombination.

Methods: Total RNA was isolated from the lymphocytes of 6 patients recovered from SARS. mRNA was isolated and reverse transcribed into cDNA.

[Apoptosis of human hepatoma HepG2 cells induced by emodin in vitro].

Background & Objective: Emodin (3-methyl-1,6,8-trihydro- xyanthrax-quinone) is the main effective composition of some Chinese herbs. Previous studies showed that emodin could inhibit the proliferation of some kind of tumor cells, such as breast cancer and lung cancer, while the mechanism(s) by which emodin suppresses tumor growth remains unknown. The study was designed to investigate the inhibitory effects and mechanisms of emodin-induced cell death in human hepatoma cell HepG2.

[Construction and significance of directional expression cDNA library from myeloid leukemia cell line U937].

To construct the cDNA expression library from human U937 cell, total RNA and purified mRNA in myeloid leukemia cell line U937 were extracted. The first and second strand of cDNA were synthesized through reverse transcription. After blunting the cDNA termini, the cDNA fragments were connected with EcoR I adapters, and the end of EcoR I adapters was phosphorylated.
