Materials And Methods: CL1-5-F4-bearing mice were divided into control, 40 mg/kg, and 60 mg/kg magnolol groups, once tumors reached 100 mm Tumor growth and body weight were monitored biweekly, and after 13 days, mice were euthanized for tumor and organ collection for subsequent staining.

Magnolol Induces Apoptosis Through Extrinsic/intrinsic Pathways and Attenuates NF-κB/STAT3 Signaling in Non-small-cell Lung Cancer Cells.

Background/aim: Non-small-cell lung cancer (NSCLC) is the most common type of lung cancer worldwide, and treatment outcomes are still poor. Magnolol, a hydroxylated biphenyl isolated from Magnolia officinalis, was found to be effective against hepatocellular carcinoma via inactivating nuclear-factor-kappa B (NF-B) signaling. However, whether magnolol targets not only NF-B but also other factors in NSCLC and may contribute to the suppression of tumor progression is unclear.

Induction of Apoptosis and Inhibition of EGFR/NF-κB Signaling Are Associated With Regorafenib-sensitized Non-small Cell Lung Cancer to Cisplatin.

Background/aim: The combination of regorafenib with cisplatin/pemetrexed has indicated controllable safety and encouraging antitumor activity in non-small cell lung cancer (NSCLC) patients. However, the anti-NSCLC effects and action mechanisms of regorafenib combined with cisplatin is ambiguous. The major goal of the study was to study the inhibitory effects and action mechanisms of regorafenib combined with cisplatin in NSCLC cells.

Association of p53 codon 72 genotypes and clinical outcome in human papillomavirus-infected lung cancer patients.

Background: We recently reported that high-risk human papillomavirus (HPV) 16/18 E6 protein was associated with p53 protein degradation in lung cancer. The present study addressed the relationship between the different p53 genotypes and HPV oncoprotein expression with respect to p53 protein degradation and clinical outcome in primary lung cancer patients.

Methods: We examined whether p53 codon 72 polymorphism and HPV oncoprotein expression could be associated with patients' outcome by collecting 319 lung tumors from patients with non-small cell lung cancer to determine p53 codon 72 polymorphisms, HPV 16/18 infection, and HPV 16/18 E6 and p53 protein expression by polymerase chain reaction (PCR)-restriction fragment length polymorphism, nested-PCR, and immunohistochemical analysis.

Expression status of ribonucleotide reductase small subunits hRRM2/p53R2 as prognostic biomarkers in stage I and II non-small cell lung cancer.

Overexpression of ribonucleotide reductase M2 (hRRM2) and p53-dependent RR small subunit (p53R2) has been correlated with tumor malignancy and progression in several types of cancer. The aim of this study was to determine the association of p53R2/hRRM2 expression with clinicopathological characteristics of stage I and II non-small cell lung cancer (NSCLC). Immunohistochemistry was conducted on a tissue array that included 92 samples.

cIAP2 upregulated by E6 oncoprotein via epidermal growth factor receptor/phosphatidylinositol 3-kinase/AKT pathway confers resistance to cisplatin in human papillomavirus 16/18-infected lung cancer.

Purpose: Inhibitors of antiapoptosis protein (IAP) have been implicated in the resistance to cisplatin. Therefore, verifying which pathway is involved in cIAP2 upregulation may be helpful in finding a feasible pathway inhibitor to increase the chemotherapeutic efficacy in human papillomavirus (HPV)-infected lung cancer.

Experimental Design: Specific inhibitors of different pathways were used to verify which pathway is involved in cIAP2 transcription.

p53R2 expression as a prognostic biomarker in early stage non-small cell lung cancer.

p53R2 is a small subunit of ribonucleotide reductase (RR) which has 80% homology to hRRM2 and metastasis-suppressing potential. Previous reports suggested that the expression of p53R2 is used as a prognostic factor and chemotherapy response indicator in several types of cancer. This study aimed to elucidate the association of p53R2 expression and the clinicopathological characteristics of early stage non-small cell lung cancer (NSCLC).

O6-Methylguanine-DNA methyltransferase hypermethylation modulated by 17beta-estradiol in lung cancer cells.

Background: Our recent report indicated that MGMT hypermethylation is more common in squamous cell carcinomas (SCC) in males, and smokers than in adenocarcinomas (ADC) in females, and nonsmokers. More interestingly, MGMT hypermethylation in SCC and ADC was pronouncedly influenced by gender factor, not by smoking status. We questioned whether 17beta-estradiol could modulate the machinery of promoter methylation to cause the gender difference of MGMT hypermethylation in lung cancer.

Association of O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation with p53 mutation occurrence in non-small cell lung cancer with different histology, gender, and smoking status.

Background: O(6)-methylguanine-DNA methyltransferase (MGMT) promoter methylation has been demonstrated to associate with the G:C-->A:T transition mutation in the p53 gene of lung tumors. The purpose of this study is to clarify whether MGMT promoter methylation is not only associated with the shift from the G:C-->A:T mutation in the p53 gene but also whether MGMT increases other mutation patterns in lung tumors.

Materials And Methods: To further verify whether a different prevalence of MGMT promoter methylation is observed in lung tumors with a different tumor histology, gender, and smoking status, 220 lung tumors were collected to evaluate the status of MGMT promoter methylation and p53 mutation using methylation-specific PCR (MSP) and direct sequencing, respectively.

DNA damage and endoplasmic reticulum stress mediated curcumin-induced cell cycle arrest and apoptosis in human lung carcinoma A-549 cells through the activation caspases cascade- and mitochondrial-dependent pathway.

Curcumin, a major component of the Curcuma species, is known to have antioxidant, anti-inflammatory properties and induce apoptosis of cancer cells, however, the precise molecular mechanisms of apoptosis in vitro are unclear. In this study, we showed that curcumin, a plant product containing the phenolic phytochemical, caused DNA damage and endoplasmic reticulum (ER) stress and mitochondrial-dependent-induced apoptosis through the activation of caspase-3 at a treatment concentration of 30 microM in human lung cancer A-549 cells. In contrast, treatment with 5-10 microM of curcumin did not induce significant apoptosis, but rather induced G2/M-phase arrest in A-549 cells.

Effects of aspirin on the in vitro and in vivo acetylation of 2-aminofluorene in Sprague-Dawley rats.

The present study was undertaken to determine the effect of acetylsalicylic acid acid on the in vitro N-acetyltransferase (NAT) enzyme activity and in vivo acetylation of 2-aminofluorene in laboratory rats. In the in vitro experiments, cytosols of blood, bladder, colon and liver cells, with or without acetylsalicylic acid co-treatment, showed different percentages of 2-aminofluorene acetylation. The data indicated that there was decreased NAT activity associated with increased acetylsalicylic acid in the cytosol reaction.

Effects of a membrane-permeable radical scavenger, Tempol, on intraperitoneal sepsis-induced organ injury in rats.

There is good evidence that endotoxemia, sepsis, and septic shock are associated with the generation and release of reactive oxygen species (ROS) such as superoxide anion (O2), indicating that oxygen-derived free radicals play an important role in the pathogenesis of sepsis/shock. Studies on the application of free oxygen radical scavengers to limit the damage to tissues and organs have been recently attempted. A stable piperidine nitroxide of low molecular weight (Tempol) can permeate biological membranes and scavenge O2 in vitro and in vivo.

Comparison of terbutaline and dobutamine in rats with endotoxemia.

It is generally accepted that bacterial endotoxin (lipopolysaccharide, LPS) acts via endogenous mediators leading to endotoxicity. Among these endogenous mediators, tumor necrosis factor-alpha (TNF-alpha) seems to induce all characteristics for endotoxemia. Inhibition of TNF-(alpha production by cAMP-elevating agents has been well documented.
