SERPINA4 is a novel independent prognostic indicator and a potential therapeutic target for colorectal cancer.

Serpina family A member 4 (SERPINA4), also known as kallistatin, exerts important effects in inhibiting tumor growth and angiogenesis in many malignancies. However, the precise role of SERPINA4 in CRC has not been fully elucidated. The present study aimed to investigate the expression of SERPINA4 and its clinical significance in CRC.

[Relationship between multi-gene proteins in colorectal carcinoma complicated with chronic schistosomiasis: an immunohistochemical study by using tissue microarray techniques].

Objective: To investigate the relationship between p53, COX-2, Bax, c-myc genes and colorectal carcinoma complicated with chronic schistosomiasis.

Methods: One hundred and sixty patients with colorectal carcinoma were selected and divided into two groups; a schistosomiasis group (colorectal carcinoma complicated with chronic schistosomiasis, n = 80) and a non-schistosomiasis group (colorectal carcinoma uncomplicated with chronic schistosomiasis, n = 80). The tissue microarray techniques and immunohistochemistry method were used in all the patients to detect the expressions of p53, COX-2, Bax and c-myc proteins.

Higher LRRFIP1 expression in glioblastoma multiforme is associated with better response to teniposide, a type II topoisomerase inhibitor.

Previous studies from this laboratory indicated that microRNA-21 (miR-21) contributes to chemoresistance of glioblastoma multiforme (GBM) cells to teniposide, a type II topoisomerase inhibitor. We also showed that LRRFIP1 is a target of miR-21. In this study, we found that higher baseline LRRFIP1 expression in human GBM tissue (n=60) is associated with better prognosis upon later treatment with teniposide.

N-myc downstream-regulated gene 1/Cap43 may function as tumor suppressor in endometrial cancer.

Purpose: N-myc downstream-regulated gene 1 (NDRG1) reportedly regulates tumor progression in various cancers. Our previous studies showed that NDRG1 was aberrantly overexpressed in human endometrial cancer tissues. The purpose of the present study was to investigate the role of NDRG1 in endometrial carcinogenesis.

[Effects of urantide, a urotensin receptor inhibitor, on acute hepatocyte apoptosis in mice].

Objective: To explore the effects of urantide, a urotensin II receptor (UT) inhibitor, on lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute hepatocyte apoptosis in mice.

Methods: Male BALB/c mice were randomly divided into 4 groups (n = 6 each): normal control, pre-treatment control, model and pre-treatment model. The pre-treatment control and pre-treatment model groups received urantide (0.

The expression of protein inhibitor of activated signal transducers and activators of transcription 3 in the evolutionary process of gastric cancer.

Objective: To study the expression of PIAS3 (protein inhibitor of activated signal transducers and activators of transcription 3) in the evolutionary process of gastric cancer.

Methods: Samples were taken from the endoscopic biopsy specimens of 125 patients. Gastric mucosal lesions were diagnosed in HE staining, and chronic atrophic gastritis (CAG) with intestinal metaplasia (IM) were distinguished in AB-PAS and HID-AB staining.

PIAS3 expression in human gastric carcinoma and its adjacent non-tumor tissues.

Objective: PIAS3 is the endogenous inhibitor of STAT3, which has been implicated in the pathogenesis of many cancers. However, the effect of PIAS3 on human tumors remains elusive. The aim of this article is to investigate the expression of PIAS3 in gastric carcinoma and its adjacent non-tumor tissues.
