This study aimed to investigate the expression of β-catenin in hepatocellular carcinoma (HCC) tissues and its relationship with α-fetoprotein (AFP) in HCC. Immunohistochemistry was used to determine the expression of β-catenin in normal liver tissues (n=10), liver cirrhosis tissues (n=20), and primary HCC tissues (n=60). The relationship between β-catenin expression and clinical parameters of HCC was investigated. Real-time PCR and Western blotting were used to detect the mRNA and protein expression levels of β-catenin in the liver cancer cell line SMMC-7721 transfected with a plasmid encoding AFP, and also the mRNA and protein expression levels of β-catenin were measured in the liver cancer cell line Huh7 before and after the transfection with AFP shRNA plasmids...

MicroRNAs (miRNAs) function as oncogenes or tumor suppressors and are dysregulated in cancer. miRNAs therefore represent promising therapeutic targets for cancer. Small molecules that could modulate the expression of miRNAs would thus have potential as anticancer agents. Library screening of small molecules targeting miRNAs is a useful technology platform for anticancer drug development. Here, we describe a hepatocellular carcinoma (HCC) cell-based luciferase reporter system which could be used to screen for small molecule modulators of tumor suppressor microRNA-34a...

Response rates to conventional chemotherapeutics remain unsatisfactory for hepatocellular carcinoma (HCC) due to the high rates of chemoresistance and recurrence. Tumor-initiating cancer stem-like cells (CSLCs) are refractory to chemotherapy, and their enrichment leads to subsequent development of chemoresistance and recurrence. To overcome the chemoresistance and stemness in HCC, we synthesized a Pt nanocluster assembly (Pt-NA) composed of assembled Pt nanoclusters incorporating a pH-sensitive polymer and HCC-targeting peptide...

Tumor necrosis factor-related apoptosis-induced ligand (TRAIL) induces apoptosis selectively in cancer cells without affecting the majority of normal human cells. However, hepatocellular carcinoma (HCC) cells often display resistance to TRAIL-induced apoptosis. Ibulocydine (IB) is an isobutyrate ester pro-drug of a novel synthetic Cdk inhibitor that targets Cdk7 and Cdk9. In this study, we show that treatment with subtoxic doses of IB in combination with TRAIL displays potent cytotoxicity in TRAIL-resistant human HCC cells...

BACKGROUND: A number of complex and rare mutations in epidermal growth factor receptor (EGFR) gene have been identified and the clinical implication of serum EGFR ligands has also been reported. However, the prognostic significance of these mutations and also the serum EGFR and its ligands in Non-Small Cell Lung Carcinoma (NSCLC) has remained a challenging issue. This study is aimed at finding the prognostic importance of EGFR rare mutations and serum EGFR, amphiregulin (AR), and TGF-α (Transforming Growth Factor-alpha) in NSCLC...

In the oral cavity, the tongue is the anatomic subsite most commonly involved by invasive squamous cell carcinoma. Current treatment protocols often require significant tissue resection to achieve adequate negative margins and optimal local tumor control. Reconstruction of the tongue while preserving and/or restoring its critical vocal, chewing, and swallowing functions remains one of the major challenges in head and neck oncologic surgery. We investigated the in vitro feasibility of fabricating a novel combinatorial construct using porcine small intestinal submucosa extracellular matrix (SIS-ECM) and human gingival mesenchymal stem cells (GMSCs) as a GMSC/SIS-ECM tissue graft for the tongue reconstruction...

Yang Cong, Ge Shen, Shikai Wu, Ruimin Hao
Out-of-field tumor response, which is also called abscopal effect, bystander effect, or non-target effect, can be regarded as localized irradiation induced systemic antitumorigenic effects, indicating shrinkage of a tumor distant from the irradiated site. Although abscopal effect has been documented in several tumor types, it is a very rare phenomenon which is clinically reported in non-small-cell-lung carcinoma (NSCLC). Herein, we represent a rare case of patient with NSCLC with two lesions in the upper lobe of left lung who, after receiving stereotactic ablative radiation therapy (SABR) to one of the tumors, had an apparent spontaneous regression of the other mass in the lung, suggestive of a radiation-induced abscopal effect...

Although obesity is a well-known risk factor for cancer, the association between obesity and cancer survival remains controversial. This is partially due to the inability of conventional obesity measures to directly assess adiposity or adipose tissue distribution. As a metabolic organ, visceral adipose tissue (VAT) secrets a variety of cytokines and cytokine-like factors, potentially affecting cancer survival. The objective of this review was to investigate the influence of imaging-assessed VAT on cancer survival...

Primary small-cell carcinoma arising from the bladder (SmCCB) is uncommon. It differs from urothelial carcinoma (UC), the most common type of bladder cancer, with respect to its cell of origin, biology, and prognosis. Biologically, prostatic SmCCB is much more aggressive than UC, and the prognosis for cases with distant metastasis is especially poor. We report here a case of primary SmCCB (cT3bN1M0) treated with radical cystectomy.

Lung carcinoma is the leading cause of cancer-related death worldwide, and among this cancer, non-small cell lung carcinoma (NSCLC) comprises the majority of cases. Furthermore, recurrence and metastasis of NSCLC correlate well with CD133+ve tumor cells, a small population of tumor cells, which has been designated as cancer stem cells (CSC). We here for the first time have demonstrated high expression of D2 dopamine (DA) receptors in CD133+ve adenocarcinoma NSCLC cells. Also, activation of D2 DA receptors in these cells significantly inhibited their proliferation, clonogenic ability and invasiveness by suppressing extracellular-signal-regulated kinases 1/2 (ERK1/2) and AKT, downregulation of octamer-binding transcription factor 4 (Oct-4) expression and matrix metalloproteinase-9 (MMP-9) secretion by these cells...

CASE REPORT: We show long-term high-quality survival following single-agent treatment with a progesterone receptor antagonist in two cases of advanced metastatic cancer. Because no biopsy was performed (patient refused) the exact type of lung cancer was not determined but the majority of oncologists who evaluated the patient thought that the rapid onset and syndrome of inappropriate anti-diuretic hormone was more consistent with small-cell lung cancer. The US Food and Drug Association granted a compassionate-use investigational new drug approval for use of single-agent 200 mg mifepristone orally/day to a moribund woman with never-treated metastatic lung cancer and a male with bilateral renal cell carcinoma who had undergone only a unilateral hemi-nephrectomy...

BACKGROUND: This study was designed to investigate potential molecules that predict chemosensitivity to pemetrexed (Alimta®) in surgically resected non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Chemosensitivity to ALM and other drugs was assessed by succinate dehydrogenase inhibition (SDI) test in 69 NSCLC samples (55 adenocarcinomas, and 14 squamous cell carcinomas). The mRNA expression levels of Alimta®-target enzymes [thymidylate synthase (TYMS); dihydrofolate reductase (DHFR) and glycinamide ribonucleotide formyltransferase (GARFT)], Alimta®-metabolizing enzymes [γ-glutamyl hydrase (GGH) and folylpolyglutamate synthase] and an Alimta® transporter [reduce folate carrier (RFC)] were measured and examined for potential correlations to chemosensitivity...

Hepatocellular carcinoma (HCC) is one of the most lethal types of cancer worldwide, with poor prognosis and limited treatments. In order to identify novel therapeutic targets that will lead to development of effective therapies with manageable side effects, we tested the hypothesis that knocking-down galactokinase (GALK1) or galactose-1 phosphate uridylyltransferase (GALT) gene expression would control the growth of cultured hepatoma cells. Our results showed small interfering RNA (siRNA) against GALK1 or GALT inhibited the growth of HepG2 cells in culture...

Transcription factor CCAAT/enhancer-binding protein delta (CEBPD) plays multiple roles in tumor progression. Studies have demonstrated that cisplatin (CDDP) induced CEBPD expression and had led to chemotherapeutic drug resistance. However, the underlying molecular mechanisms of CDDP-regulated CEBPD expression and its relevant roles in CDDP responses remain elusive. MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression in a sequence-specific manner. Abnormal miRNAs expression is associated with tumor progression...

Thioredoxin reductase (TrxR) is a component of several redox-sensitive signaling cascades that mediate important biological processes such as cell survival, maturation, growth, migration and inhibition of apoptosis. The expression levels of TrxR1 in some human carcinoma cell lines are nearly 10 times higher than those in normal cells. Ethaselen is a novel antitumor candidate that exerts potent inhibition on non-small cell lung cancer (NSCLC) by targeting TrxR. In this study we explored the relationship between the ethaselen dose and TrxR activity level and the relationship between TrxR degradation and tumor apoptosis in a human lung carcinoma A549 xenograft model...

Non-small cell lung cancer is the most common form of lung cancer, accounting for about 85% of all cases and is further subdivided into adenocarcinoma, squamous cell, and large cell carcinoma. Necitumumab (Portrazza™, Eli Lilly and Company) is an anti-epidermal growth factor receptor monoclonal antibody approved for the first-line treatment of squamous cell non-small cell lung cancer in combination with cisplatin and gemcitabine. The safety and efficacy of necitumumab has been evaluated in two-phase III clinical trials, one demonstrating a lack of efficacy in non-squamous non-small cell lung cancer and another demonstrating improvement in overall survival and progression-free survival in squamous cell non-small cell lung cancer...
