Oxidative stress is involved in a variety of diseases. Prospective studies investigating the relationship between oxidative stress biomarkers and the status and development of colorectal cancer (CRC) are scarce; previous studies have failed to establish a relationship between the serum total oxidant/antioxidant status and CRC. Therefore, we compared the total serum oxidant/antioxidant levels of CRC patients and healthy subjects, and analyzed their clinical significance in the CRC. Fasting blood samples from 132 CRC patients and 64 healthy subjects were collected...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most fatal human cancers due to its complicated genomic instability. PDAC frequently presents at an advanced stage with extensive metastasis, which portends a poor prognosis. The known risk factors associated with PDAC include advanced age, smoking, long-standing chronic pancreatitis, obesity, and diabetes. Its association with genomic and somatic mutations is the most important factor for its aggressiveness. The most common gene mutations associated with PDAC include KRas2, p16, TP53, and Smad4...

The activation of AKT is one of the causes of resistance to epidermal growth factor receptor (EGFR)- tyrosine kinase inhibitors (TKIs). Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) combines with related receptors to trigger apoptosis or protect the cells against TRAIL apoptosis. This research focused on the association of EGFR and KRAS mutations with expression of AKT, p-AKT, DR5 and DcR1 in non-small cell lung cancer. 82 NSCLC patients were included in the study. xTAG liquichip techonolgy (xTAG-LCT) was applied to investigate the genetic mutation of EGFR and KRAS, Quantitative Real-time PCR was used to test the mRNA expression of AKT, DR5 and DcR1 and Western Blot was applied to test the protein expression of AKT, p-AKT, DR5, and DcR1...

BACKGROUND: Abnormal telomere length is widely reported in various human cancers, and it is considered to be an important hallmark of cancer. However, there is remarkably little consensus on the value of telomere length in the prognostic evaluation of esophageal cancers. Here, we attempted to determine the association of variable telomere length with clinical outcome of esophageal cancer patients. MATERIALS AND METHODS: Using real-time quantitative PCR, we examined relative telomere lengths (RTL) in a cohort of esophageal cancer and normal esophageal tissues, and statistically investigated the association between RTL and clinical outcomes of esophageal cancer patients...

OBJECTIVES: Activating mutations in the epidermal growth factor receptor (EGFR) are strongly predictive of EGFR-tyrosine kinase inhibitor (TKI) activity in non-small cell lung cancer (NSCLC). However, primary resistance to EGFR-TKIs occurs in approximately 20-30% of NSCLC patients with EGFR mutations. The goal of this study was to determine whether p16/CDKN2A homozygous deletion (HD) is associated with primary resistance to EGFR-TKIs in lung adenocarcinoma patients with EGFR activating mutations...

Cigarette smoking is a major cause of lung cancer. Tumor-associated endothelial cells (TAECs) play important roles in tumor angiogenesis and metastasis. However, whether cigarette smoking can trigger genesis of lung TAECs has not been reported yet. In the current study, we used lung endothelial cell (EC) lines as a model to study the pathological effect of cigarette smoke extracts (CSEs) on human lung ECs, and found that a lower dose of 4% CSEs obviously caused abnormal morphological changes in ECs, increased the permeability of endothelial monolayer, while a higher concentration of 8% CSEs caused EC apoptosis...

The Cullin-RING ubiquitin ligases 4 is implicated in controlling cell cycle, DNA damage repair and checkpoint response based on studies employing cell lines and mouse models. CRL4 proteins, including CUL4A and CUL4B are often highly accumulated in human malignancies. Elevated CRL4 attenuates DNA damage repair and increases genome instability that is believed to facilitate tumorigenesis. However, this has yet to be evaluated in human cancer patients. In our study, 352 lung cancer and 62 normal lung specimens of Asian origin were constructed into tissue microarrays (TMAs) of four distinct lung cancer subtypes...

Importance: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) has a favorable prognosis, and p16 immunohistochemistry is a surrogate marker of high-risk HPV infection and strong prognosticator. Given this favorable prognosis, treatment de-escalation for p16-positive OPSCC is now being considered with the goal of decreasing treatment-associated morbidity without compromising tumor control. The role of adjuvant chemotherapy in this setting is becoming increasingly unclear...
