Protein arginine methyltransferase 5 (PRMT5) plays critical roles in a wide variety of biological processes, including tumorigenesis. By screening a library of small chemical compounds, we identified eight compounds that selectively inhibit the PRMT5 enzymatic activity, with IC50 values ranging from 0.1 to 6 μM. Molecular docking simulation and site-directed mutagenesis indicated that identified compounds target the substrate-binding site in PRMT5. Treatment of lung cancer cells with identified inhibitors led to inhibition of the symmetrical arginine methylation of SmD3 and histones and the cellular proliferation...

Colorectal cancer (CRC) is a leading cause of tumor-related morbidity and mortality worldwide, with mortality most often attributable to metastatic disease. Bevacizumab, a humanized monoclonal antibody targeting vascular endothelial growth factor, has a significant role in the treatment of metastatic CRC (mCRC). However, patient access to bevacizumab may be limited in some regions or circumstances, owing to factors related to insurance coverage, reimbursement, patient out-of-pocket costs, or availability. As a result, outcomes for patients with mCRC may be worsened...

The tumors of the female genital tract represent a leading cause of morbidity and mortality among women worldwide. Substantial progresses have been made in ovarian cancer, with the increasing knowledge about BRCA mutated tumors and the recent development of PARP inhibitors, and in cervical cancer, thanks to extensive screening and widespread of vaccination against Human Papilloma Virus. Nevertheless many needs remain unmet, advanced stage diseases are still incurable and cervical and endometrial carcinoma, as well as platinum-resistant ovarian carcinoma, can certainly be classifiable among the cancers with poor sensitivity to conventional chemotherapy...

Isoalantolactone has recently been revealed to induce apoptosis in several types of cancer. However, little is reported on its anti-tumor potential on human lung cancer. Our present study was designed to investigate its effects on human lung squamous carcinoma SK-MES-1 cells. We found that Isoalantolactone induced cellular and DNA morphological changes and decreased the viability of SK-MES-1 cells. It significantly inhibited the growth of SK-MES-1 cells through apoptosis in a dose-dependent manner via activation of p53...

PURPOSE: Circulating molecules play important roles in lung cancer diagnosis. In addition, plasma lactate dehydrogenase (LDH) and creatine kinase (CK) have been shown to be closely related to tumor progression in breast cancer, prostate cancer, and colonel cancer. However, the relationships between LDH and CK levels with metastasis occurrence and the survival status of lung cancer patients remain unclear. EXPERIMENTAL DESIGN: A total of 1142 lung cancer patients were enrolled in this study and were separated into negative or positive groups, according to the plasma levels of CK or LDH...

The era of immunotherapy has changed the face of how we approach treatment for many oncologic and hematologic malignancies. Lung cancer has been in the forefront of checkpoint inhibition for the past 2 years and has paved the path for other subspecialties. While PD-1 inhibitors nivolumab and pembrolizumab have been approved for non-small cell lung cancer (NSCLC), this review focuses on atezolizumab, its landmark studies, and ongoing trials. Atezolizumab is the first programmed death ligand 1 (PD-L1) inhibitor to receive US Food and Drug Administration (FDA) approval for metastatic NSCLC patients who have progressed on frontline chemotherapy...

Lung cancer is the leading cause of cancer mortality. A substantial progress in the understanding of lung cancer biology has resulted in several promising targeted therapies for advanced disease. Druggable targets today include point mutations such as EGFR, BRAF and re-arrangements in genes such as ALK and ROS1. Liquid biopsies collecting e.g., circulating tumor DNA (ctDNA) reflects overall tumor information and is not biased by analyzing of only a small fraction of the tumor and is always accessible in contrast to the lung cancer tissue...

BACKGROUND/PURPOSE: Surgery followed by radioiodine is a mainstay of treatment for thyroid cancers of follicular origins. However, about 5% of the thyroid cancers are non-operable and/or radioiodine-refractory diseases, which are either locally advanced or metastatic and result in a survival of less than 5 years. How to treat this population of thyroid cancer patients becomes a critical issue requiring further understanding of the tumor's genetic information. METHODS: We used formalin-fixed paraffin-embedded specimens of 22 fatal thyroid cancers and their corresponding non-tumor parts, if available, to yield genomic DNA, and applied the Ion Torrent™ Personal Genome Machine (IT-PGM) System (Life Technologies), a next generation sequencing technology, to interrogate 740 mutational hotspots in 46 oncogenes...

Large-scale sequencing efforts have described the mutational complexity of individual cancers and identified mutations prevalent in different cancers. As a complementary approach, allele-specific competitive blocker PCR (ACB-PCR) is being used to quantify levels of hotspot cancer driver mutations (CDMs) with high sensitivity, to elucidate the tissue-specific properties of CDMs, their occurrence as tumor cell subpopulations, and their occurrence in normal tissues. Here we report measurements of PIK3CA H1047R mutant fraction (MF) in normal colonic mucosa, normal lung, colonic adenomas, colonic adenocarcinomas, and lung adenocarcinomas...

Metastatic non-small-cell lung cancer (NSCLC) with activating EGFR mutations responds very well to first and second generation tyrosine-kinase inhibitors (TKI) including gefitinib, erlotinib and afatinib. Unfortunately, drug resistance will eventually develop and about half of the cases are secondary to the emergence of acquired T790M somatic mutation. In this work, we prospectively recruited 68 patients with metastatic EGFR-mutated NSCLC who have developed progressive disease after first-line TKI with or without subsequent TKI and/or other systemic therapy...
