Infrared spectroscopy and microscopy in cancer research and diagnosis.
Since the middle of 20(th) century infrared (IR) spectroscopy coupled to microscopy (IR microspectroscopy) has been recognized as a non destructive, label free, highly sensitive and specific analytical method with many potential useful applications in different fields of biomedical research and in particular cancer research and diagnosis. Although many technological improvements have been made to facilitate biomedical applications of this powerful analytical technique, it has not yet properly come into the...
HCG variants, the growth factors which drive human malignancies.
The term human chorionic gonadotropin (hCG) refers to a group of 5 molecules, each sharing the common amino acid sequence but each differing in meric structure and carbohydrate side chain structure. The 5 molecules are each produced by separate cells and each having separate biological functions. hCG and sulfated hCG are hormones produced by placental syncytiotrophoblast cells and pituitary gonadotrope cells. Hyperglycosylated hCG is an autocrine produced by placental cytotrophoblast cells. Hyperglycosylate...
The warts gene as a novel target of the Drosophila DRE/DREF transcription pathway.
The Hippo tumor suppressor pathway in Drosophila represses expression of DIAP1 and Cyclin E via inactivation of the transcription co-activator Yorkie, resulting in cell cycle arrest and induction of apoptosis. The warts (wts) gene is well known as a core kinase in this pathway, but its transcriptional regulation has yet to be clarified. In Drosophila, DREF binds to a target sequence named DRE (5'-TATCGATA) and regulates transcription of cell proliferation-related genes containing the DRE sequence in their p...
Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL/TNFSF10) has been reported to specifically induce malignant cell death being relatively nontoxic to normal cells. Since its identification 15 years ago, the antitumor activity and therapeutic value of TRAIL have been extensively studied. Five receptors quickly emerged, two of them being able to induce programmed cell death in tumor cells. This review takes a comprehensive look at this ligand and its receptors, and its potential role in primary b...
Understanding the role of miRNA in regulating NF-κB in blood cancer.
MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by binding to complementary sequences in mRNAs encoding downstream target genes. A large variety of cellular processes, including differentiation, development, apoptosis and cell cycle progression, are dependent on miRNA-mediated suppression of gene expression for their regulation. As such, it is unsurprising that these small RNA molecules are associated with signaling networks that are often altered in various diseases, including ma...
Targeted ovarian cancer treatment: the TRAILs of resistance.
Ovarian cancer (OC) is the leading cause of death from gynecological malignancies. Although most patients respond to the initial therapy when presenting with advanced disease, only 10-15% maintain a complete response following first-line therapy. Recurrence defines incurable disease in most cases. Despite improvements with conventional chemotherapy combinations, the overall cure rate remained mostly stable over the years. Increased long-term survival in OC patients will only be achieved through a comprehens...
Molecular signature and pathway analysis of human primary squamous and adenocarcinoma lung cancers.
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, with a poor response to chemotherapy and low survival rate. This unfavorable treatment response is likely to derive from both late diagnosis and from complex, incompletely understood biology, and heterogeneity among NSCLC subtypes. To define the relative contributions of major cellular pathways to the biogenesis of NSCLC and highlight major differences between NSCLC subtypes, we studied the molecular signatures of lung adenocarcinoma...
To determine the prognostic value of FOXO1, GATA3 and Annexin-1 expression in breast cancer.
Prognostic significance of aberrant gene methylation in gastric cancer.
Promoter methylation acts as an important alternative to genetic alterations for gene inactivation in gastric carcinogenesis. Although a number of gastric cancer-associated genes have been found to be methylated in gastric cancer, valuable methylation markers for early diagnosis and prognostic evaluation of this cancer remain largely unknown. In the present study, we used methylation-specific PCR (MSP) to analyze promoter methylation of 9 gastric cancer-associated genes, including MLF1, MGMT, p16, RASSF2, h...
