Programmed death ligand 1 (PD-L1) as one the most important immune checkpoint was verified to involve in chemotherapy resistance in non-small cell lung cancer (NSCLC). Ginsenoside Rg3 is isolated from Chinese herb-Panax ginseng which is recognized to boost immune and has anti-cancer activity against a majority of carcinomas including NSCLC. In this study, we aim to identify whether Rg3 could attenuate the PD-L1 expression induced by resistance to cisplatin and draw out the underlying mechanisms of PD-L1 in this process...

Merkel cell carcinoma (MCC) frequently contains integrated copies of Merkel cell polyomavirus DNA that express a truncated form of Large T antigen (LT) and an intact Small T antigen (ST). While LT binds RB and inactivates its tumor suppressor function, it is less clear how ST contributes to MCC tumorigenesis. Here we show that ST binds specifically to the MYC homolog MYCL (L-MYC) and recruits it to the 15-component EP400 histone acetyltransferase and chromatin remodeling complex. We performed a large-scale immunoprecipitation for ST and identified co-precipitating proteins by mass spectrometry...

BACKGROUND: Arsenic is a well-documented human carcinogen, and studies on urinary and skin cancers have shown that the carcinogenicity of ingested arsenic has cell-type specificity. To evaluate whether this is also true for lung cancers, we conducted a study on 243 townships in Taiwan. METHODS: The arsenic levels were assessed using measurement reports from a previous survey, and the incidence of lung cancer was assessed using the data gathered by the National Cancer Registry Program...

Although radiotherapy remains the most powerful as well as the primary treatment modality for nasopharyngeal carcinoma (NPC), approximately 20% of NPC patients still have local recurrence. Carbonic anhydrase IX (CAIX)-related signaling pathways that mediate radioresistance have been found in various kinds of cancer. However, the role of CAIX in NPC radioresistance is still unknown. In this study, we investigated the effect of CAIX silencing on sensitization to ionizing radiation in NPC by using Lipofectamine 2000, which delivers small interfering ribonucleic acid (siRNA) that targets CAIX...

Elevated VEGF mRNA (-ΔCT) was significantly associated with adenocarcinoma histology (vs squamous) and advanced NSCLC clinical stages in a univariable analysis; however, this association did not remain significant in the multivariable analysis. Of interest, a Kaplan-Meier analysis showed that NSCLC patients with higher VEGF mRNA (-ΔCT ≥10) had a significantly poorer overall survival and shorter postoperative relapse time in adenocarcinoma and in stage III/IV than those with VEGF mRNA of -ΔCT <10 (P < 0...

BACKGROUND: With advent of personalized medicine, precise classification of malignant tumors becomes essential. Squamous cell carcinoma (SCC) is rarely found in serous effusions and has morphologic and immunohistochemical (IHC) overlap with other neoplasms. METHODS: 17-year review identified 49 fluids from 26 patients where SCC was recognized. RESULTS: SCC was more frequent in pleural fluid (84%) and rare in other effusions. Lung SCC was common (65%), followed by head and neck (16%), with other origins less represented...

BACKGROUND: One immunotherapeutic agent for patients with advanced non-small cell lung carcinoma, pembrolizumab, has a companion immunohistochemistry (IHC)-based assay that predicts response by quantifying programmed death-ligand 1 (PD-L1) expression. The current study assessed the feasibility of quantifying PD-L1 expression using cytologic non-small cell lung carcinoma specimens and compared the results with those from small biopsy and surgical resection specimens. METHODS: PD-L1 expression was quantified using the IHC-based 22C3 pharmDx assay, with "positivity" defined as staining in ≥50% viable tumor cells; ≥ 100 tumor cells were required for test adequacy...

De novo hepatocellular carcinoma (HCC) post-transplantation in patients without viral hepatitis is extremely rare, with only three reported adult cases in the English literature. Here, we present a case of de novo HCC that developed in a 7-year-old female, who at 8 months of age received a liver, small bowel, spleen, and pancreas transplantation 6.5 years ago for gastroschisis and total parenteral nutrition (TPN)-related cirrhosis. The post-transplant course was complicated by Epstein-Barr virus (EBV) infection, post-transplant lymphoproliferative disease, and subsequent development of multifocal EBV-associated post-transplant smooth muscle tumors (EBV-PTSMT) in the small bowel 1 year and 10 months after transplantation, respectively...

We report a case of ALK-positive renal cell carcinoma coincident with Hodgkin lymphoma. The patient was a 19 year-old-girl without sickle cell trait. The right renal tumor was discovered concomitantly with Hodgkin lymphoma (HL). After chemotherapy for HL, right nephrectomy was performed. Microscopically, the tumor showed a solid and focally pseudo-papillary growth pattern studded with tubular structures. Most tumor cells were small bland eosinophilic cells, but rhabdoid cells, vacuolated cells, pleomorphic multinucleated giant cells were also admixed...

Intestinal neoplasms are common in zebrafish (Danio rerio) research facilities. These tumours are most often seen in older fish and are classified as small cell carcinomas or adenocarcinomas. Affected fish populations always contain subpopulations with preneoplastic lesions, characterized by epithelial hyperplasia or inflammation. Previous observations indicated that these tumours are unlikely caused by diet, water quality or genetic background, suggesting an infectious aetiology. We performed five transmission experiments by exposure of naïve fish to affected donor fish by cohabitation or exposure to tank effluent water...

The prognostic role of tumor-infiltrating tryptase(+) mast cells in human solid tumors remains controversial. Herein, we conducted a meta-analysis including 28 published studies with 4224 patients identified from PubMed and EBSCO to assess the prognostic impact of tumor-infiltrating tryptase(+) mast cells in human solid tumors. We found that tryptase(+) mast cell infiltration significantly decreased overall survival (OS) and disease-free survival (DFS) in all types of solid tumors. In stratified analyses, tryptase(+) mast cell infiltration was significantly associated with worse OS in non-small cell lung cancer, hepatocellular carcinoma and 5-year survival in colorectal cancer...

Highly upregulated in liver cancer (HULC) is a long noncoding RNA (lncRNA), which has recently been identified as a key regulator in the progression of hepatocellular carcinoma, gliomas and gastric cancer. However, its role in epithelial ovarian carcinoma (EOC) remains unknown. In this study, HULC expression was examined in EOC, borderline and benign ovarian tumors, and normal ovarian tissues by RT-PCR. Ovarian cancer cell phenotypes, as well as autophagy-associated proteins were examined after HULC overexpression or downregulation by plasmid or small interfering RNA (siRNA) transfection, respectively...

There remain gaps in knowledge concerning how vascular morphology evolves during carcinogenesis. In this study, we imaged neovascularization by label-free dark field microscopy of a DMBA-induced hamster cheek pouch model of oral squamous cell carcinoma (SCC). Wavelength-dependent imaging revealed distinct vascular features at different imaging depths and vessel sizes. Vascular tortuosity increased significantly in high-risk lesions, while diameter decreased significantly in hyperplastic and SCC lesions. Large vessels preserved the same trends seen in the original images, whereas small vessels displayed different trends, with length and diameter increasing during carcinogenesis...

Four novel water-soluble Cu(II) derivatives based on the meso-10, 15, 20-Tris (N-methyl-X-pyridyl)-5-(4'-salicyloylhydrazone) metalloporphyrin ligands (X=4, M=Zn(1) Co(2); X=2, M=Zn(3), Co(4)), have been prepared and isolated. Various physicochemical techniques indicate that complex 2 interacts with calf thymus DNA stronger than the others through partial intercalation, suggesting that Co(II) has no axial ligands at porphyrin core plays a crucial role, interestingly, 2 exhibits higher DNA binding affinity compared to 4, which could be ascribed to the influences of peripheral electronic effect of porphyrin ring...

Distinct prognostic roles of HSPB1 expression in non-small cell lung cancer Lung cancer is the leading cause of cancer morbidity and mortality around world. Heat shock protein beta-1 (HSPB1) expression is aberrantly increased in non-small cell lung cancer (NSCLC) patients. However, the roles of HSPB1 expression in the prognosis of NSCLC are still elusive. In this study, we investigated the prognostic roles of HSPB1 in NSCLC by using "The Kaplan-Meier plotter" (KM plotter) database. Our data indicated that HSPB1 mRNA low expression was correlated to better overall survival (OS) for all NSCLC patients, hazard ratio (HR) 1...
