Background: Glioblastoma (GBM) is notorious for the aggressive behaviors and easily results in chemo-resistance. Studies have shown that the use of herbal medicines as treatments for GBM as limited by the blood-brain barrier (BBB) and glioma stem cells.
Purpose: The aim of this study was to investigate the relationship between GBM suppression and α-terpineol, the monoterpenoid alcohol derived from Eucalyptus glubulus and Pinus merkusii.

The roles of apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3C (A3C) in various human malignancies are not consistent. A3C expression is correlated with early-stage breast cancer and is presented as a good prognostic factor; however, it induces fewer therapeutic effects of cytotoxic drugs in low-grade gliomas. To explore the impact of A3C on gliomas, a statistical analysis of several public databases was conducted.

To date, no study has described the characteristics of Taiwanese patients harboring PAFP lymph nodes with metastatic prostate cancer involvement. Between December 2006 and May 2015, a total of 849 consecutive patients underwent robot-assisted laparoscopic radical prostatectomy with PAFP dissection.

In this study, the impact of intradialytic hypotension on intestinal barrier integrity is being explored.
Methods: Immunohistochemical staining was used to detect the expression of 4 types of tight junction (TJ) proteins such as occludin, zonula occludens-1 (ZO-1), claudin-1, and claudin-4, in colonic samples of a group of patients receiving segmental colectomy.
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease associated with a poor prognosis and high morbidity. Early diagnosis and complete tumor removal are still the principal factors extending life expectancy in PDAC patients. Here, the relationship of neurexophillin 1 (NXPH1) and NXPH2 expressions with clinicopathological parameters of PDAC was evaluated.

It is categorized into four histological types: papillary adenocarcinoma (PAC), tubular adenocarcinoma (TAC), mucinous adenocarcinoma (MAC), and signet ring cell adenocarcinoma (SRC). Effective differentiation of the four types of adenocarcinoma will greatly improve the treatment of gastric adenocarcinoma to increase its five-year survival rate.

To differentiate GISTs from adenocarcinomas is important because the surgical processes for both are different; the former excises the tumor with negative margins, while the latter requires radical gastrectomy with lymph node dissection. Endoscopy with biopsy is used to distinguish GISTs from adenocarcinomas; however, it may cause tumor bleeding in GISTs.

Cyclin T1 and Cdk9 are the key factors of the PTEFb pathways and are overexpressed in the human head and neck carcinoma cell line. However, there have been limited studies regarding the role of cyclin T1 and Cdk9 in gastric gastrointestinal stromal tumors (GISTs).

However, few studies have investigated the role of cyclin T1 and cyclin-dependent kinase 9 (CDK9) in gastric adenocarcinoma. Therefore, this study assessed the clinical significance of cyclin T1 and CDK9 expression in gastric adenocarcinoma.

Chordomas belong to the dysontogenetic bone tumors and appear primarily in the region of the axial skeleton. Chordomas are divided into conventional, chondroid, sarcomatoid and dedifferentiated subtypes.

Our aim was to examine the relationship of UCN expression to the clinicopathological parameters of pancreatic ductal adenocarcinoma (PDAC) and histological grade of pancreatic intraepithelial neoplasia (PanIN). Tissue microarray was used to analyze UCN protein expression in 89 surgical specimens including 21 PanIN, 3 PDAC arising from PanIN, and 65 PDAC without PanIN.

Gastric adenocarcinoma is a lethal disease with high incidence in Chinese people. The purpose of this study was to evaluate the expression of urocortin (UCN) in normal gastric mucosa and gastric adenocarcinomas. Immunohistochemical analysis of UCN was performed in 112 surgical specimens (21 normal gastric mucosa specimens and 91 gastric adenocarcinoma specimens varying in histologic grade and pathologic stage).

The aim of this study was to assess the correlation of OPN and EGFR expression with hepatocellular carcinoma (HCC) progression. Expression of OPN and EGFR was assessed by immunohistochemistry in 100 HCC specimens.

Immunohistochemical analysis of EGFR, Ki67, and p53 was performed in tissue microarray slides of 9 normal glandular tissues and 150 specimens including 49 well, 58 moderately, and 43 poorly differentiated colorectal adenocarcinomas. Differences in intensity of EGFR immunostaining and the percentages of Ki67 and p53 positive cells between normal and tumor specimens were evaluated using the Student t-test, one-way ANOVA, and linear regression analysis.

Aim: To test the association of LMX1A and osteopontin (OPN) expression with histologic differentiation or pathologic stage in pancreatic ductal adenocarcinoma.
Methods: Immunohistochemical analysis was performed to determine LMX1A and OPN expression in 100 surgical specimens obtained from Chinese patients with well-differentiated (n=15), moderately differentiated (n=65), and poorly differentiated (n=20) pancreatic ductal adenocarcinomas.
Results: LMX1A and OPN immunoreactivities were undetectable in normal pancreatic glandular epithelia.
Cortactin and fascin-1 are important factors affecting progression and metastasis of carcinomas. We tested the hypothesis that cortactin and fascin expression has significant correlation with clinicopathological parameters in pancreatic and ampulla of Vater adenocarcinomas. Immunohistochemical analysis of cortactin and fascin-1 was performed in 50 pancreatic and 40 ampulla of Vater adenocarcinomas.

Cancer stem cells (CSC) with several characteristics can lead to therapeutic resistance. CD133 has been identified as a putative CSC marker in colorectal cancer; however, its functional role still needs elucidation.

The expression of HDACs in colorectal cancer specimens and the effects of SAHA on colon cancer cells and tumors of nude mice were assessed. Treatment with SAHA (3 μm) for 72 h induced downregulation of different subtypes of HDAC proteins and also induced acetylation of histone 3 and histone 4.

Cortactin, fascin and survivin have been found in several human cancers to play important roles in tumor progression, but the expression pattern of these biomarkers in gliosarcoma is unclear. Immunostaining for cortactin, fascin and survivin was assessed in 6 surgical specimens of brain gliosarcoma, and the relationship between the expression of these biomarkers and tumor size or clinical parameters were examined.
