BACKGROUND: Despite advances in early diagnosis and treatment, cancer remains the major cause of mortality in the world. The Tob/BTG antiproliferative (APRO) protein family is reported to participate in diverse human diseases. However, there's little known about their expression and prognostic values in most human cancers. METHODS: We performed a detailed cancer vs. normal analysis. The mRNA expression levels of APRO family in various cancers were analyzed via the Oncomine database...

OBJECTIVE: Lung cancer, which is the leading cause of cancer death worldwide, is influenced by a wide variety of environmental and genetic risk factors. The silent information regulator 1 (SIRT1) gene is located on the long arm of chromosome 10 (10q21.3) and has been shown to play crucial roles in lung cancer development in previous studies. In this study, we determined whether variation in the SIRT1 gene is associated with lung cancer in Chinese population. METHODS: The case-control study comprised 246 controls and 257 non-small cell lung cancer patients, comprising 79 squamous cell carcinoma patients and 124 adenocarcinoma patients...

Lung squamous cell carcinoma (SCC), accounting for approximately 30% of non-small cell lung cancer, is often refractory to therapy. Screening a small molecule library, we identified digitoxin as a high potency compound for suppressing human lung SCC growth in vitro and in vivo. Mechanistic investigations revealed that digitoxin attenuated YAP phosphorylation and promoted YAP nuclear sequestration. YAP activation led to excessive accumulation of reactive oxygen species (ROS) by downregulating the antioxidant enzyme GPX2 in a manner related to p63 blockade...

Cutaneous metastasis is considered as a hazardous condition depending on the mean survival around 9 months, which usually originates from cancers of the breast, lung, ovary, colon, and rarely from the cervix. The crucial prognostic factor of cutaneous metastasis depends on the period between the primary malignancy and cutaneous metastasis. We report two cases of the unusual presentation of squamous cell cancer of the cervix that developed vulvar and umbilical metastasis in the 5(th) month of primary treatment...

We performed a comprehensive immuno-genomic analysis of tumor microenvironment immune types (TMITs), which is classified into four groups based on PD-L1+CD8A or PD-L1+cytolytic activity (CYT) expression, across a broad spectrum of solid tumors in order to help identify patients who will benefit from anti- PD-1/PD-L1 therapy. The mRNA sequencing data from The Cancer Genome Atlas (TCGA) of 14 solid cancer types representing 6,685 tumor samples was analyzed. TMIT was classified only for those tumor types that both PD-L1 and CD8A/CYT could prefict mutation and/or neoantigen number...

Mutation burden in a tumor, presumably involving neo-antigens in the tumor tissue, is also thought to be one of the better predictors for the efficacy of immune checkpoint inhibitors. However, it is difficult to analyze the mutation burden routinely in the clinic. Here, we describe more convenient factors that can be used as surrogate markers of mutation burden. Ninety-four patients with NSCLC who underwent resection in our institution were recruited for this study. Mutation burden and major gene alterations were analyzed by using next generation sequencing...

In this study, we developed an image analysis algorithm for quantification of two potential apoptotic biomarkers in non-small-cell lung cancer (NSCLC): FLIP and procaspase-8. Immunohistochemical expression of FLIP and procaspase-8 in 184 NSCLC tumors were assessed. Individual patient cores were segmented and classified as tumor and stroma using the Definiens Tissue Studio. Subsequently, chromogenic expression of each biomarker was measured separately in the nucleus and cytoplasm and reported as a quantitative histological score...

DNA repair pathways present in all cells serve to preserve genome stability, but in cancer cells they also act reduce the efficacy of chemotherapy. The endonuclease ERCC1-XPF has an important role in the repair of DNA damage caused by a variety of chemotherapeutic agents and there has been intense interest in the use of ERCC1 as a predictive marker of therapeutic response in non-small cell lung carcinoma, squamous cell carcinoma and ovarian cancer. We have previously validated ERCC1 as a therapeutic target in melanoma, but all small molecule ERCC1-XPF inhibitors reported to date have lacked sufficient potency and specificity for clinical use...

Introduction: Our previous study identified LIM homeobox domain 6 (LHX6) as a frequently epigenetically silenced tumor-suppressor gene in lung cancer. However, its clinical value has never been evaluated, and the in-depth anti-tumor mechanism remains unclear. Methods: Public database was used for lung cancer, lung adenocarcinoma and lung squamous carcinoma patients and tissue microarray data was used for lung adenocarcinoma patients to study prognostic outcome of LHX6 expression by Kaplan-Meier and Cox-regression analysis...

Malignant cell transformation is accompanied with abnormal DNA methylation, such as the hypermethylation of certain gene promoters and hypomethylation of retrotransposons. In particular, the hypomethylation of the human-specific family of LINE-1 retrotransposons was observed in lung cancer tissues. It is also known that the circulating DNA (cirDNA) of blood plasma and cell-surface-bound circulating DNA (csb-cirDNA) of cancer patients accumulate tumor-specific aberrantly methylated DNA fragments, which are currently considered to be valuable cancer markers...

OBJECTIVES: Nivolumab has recently been shown in the phase III clinical trial CheckMate-141 to have superior survival rates compared to the current standard of care chemotherapy for recurrent or metastatic platinum-resistant head and neck squamous cell carcinoma (HNSCC). Nivolumab targets the immune inhibitory receptor programmed cell death 1 (PD-1). Programmed cell death ligand 1 (PD-L1) genomics have been poorly characterized in the context of HNSCC, including expression levels of PD-L1 in individual tumors as well as related up or down-regulated genes that might function as co-targets...

Little is known about the human lung lipidome, its variability in different physiological states, its alterations during carcinogenesis and the development of pulmonary emphysema. We investigated how health status might be mirrored in the lung lipidome. Tissues were sampled for both lipidomic and histological analysis. Using a screening approach, we characterised lipidomes of lung cancer tissues and corresponding tumour-free alveolar tissues. We quantified 311 lipids from 11 classes in 43 tissue samples from 26 patients...
