RATIONAL: The c-ros oncogene 1 receptor tyrosine kinase (ROS1)-rearrangements represent a new and rare genetic subtype of non-small-cell lung cancer. In recent years, the use of crizotinib in ROS1-rearranged lung cancer exhibits significant clinical efficacy. Crizotinib is generally well tolerated and the most frequent adverse events include visual disorders, gastrointestinal disturbances, cardiac, and endocrine abnormalities. From a cardiac perspective, crizotinib is associated with 2 main cardiac effects, QT interval prolongation and bradycardia...

The development of hepatoblastoma (HBL) is associated with failure of hepatic stem cells (HSC) to differentiate into hepatocytes. Despite intensive investigations, mechanisms of the failure of HSC to differentiate are not known. We found that oncogene Gankyrin (Gank) is involved in the inhibition of differentiation of HSC via triggering degradation of tumor suppressor proteins (TSPs) Rb, p53, C/EBPα and HNF4α. Our data show that the activation of a repressor of Gank, farnesoid X receptor, FXR, after initiation of liver cancer by Diethylnitrosamine (DEN) prevents the development of liver cancer by inhibiting Gank and rescuing tumor suppressor proteins...

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Despite the advanced surgical resection techniques and anticancer drugs currently available to treat early stage gastric cancer, the prognosis of patients with gastric cancer remains poor. The epithelial to mesenchymal transition (EMT) is an important process for the initiation of tumorigenesis. Recent studies suggested that reactive oxygen species (ROS) can promote cell migration and invasion. Thus, an imbalance of redox homeostasis can result in cancer cells exhibiting EMT properties...

Liver regeneration, an orchestrated process, is the primary compensatory mechanism following liver injury caused by various factors. The process of liver regeneration consists of three stages: Initiation, proliferation and termination. Proliferation‑promoting factors, which stimulate the recovery of mitosis in quiescent hepatocytes, are essential in the initiation and proliferation steps of liver regeneration. Proliferation‑promoting factors act as the 'motor' of liver regeneration, whereas proliferation inhibitors arrest cell proliferation when the remnant liver reaches a suitable size...

Leucine-rich glioma inactivated (LGI)3 is a secreted protein member of LGI family. We previously repo-rted that LGI3 was upregulated in adipose tissues from obese mice and suppressed adipogenesis through its receptor, a disintegrin and metalloproteinase domain-containing protein 23 (ADAM23). We demonstrated that LGI3 regulated tumor necrosis factor-α and adiponectin, and proposed that LGI3 may be a pro-inflammatory adipokine involved in adipose tissue inflammation. In this study, we analyzed adipokine and cytokine profiles in LGI3 knockout mice and demonstrated that multiple factors were increased or decreased in the adipose tissues and plasma of the LGI3 knockout mice...

Tumor-derived exosomes have emerged as promising cancer biomarkers due to their unique composition and functions. Herein, we report a stripping voltammetric immunoassay for the electrochemical detection of disease-specific exosomes using quantum dots as signal amplifiers. The assay involves three subsequent steps where bulk exosome populations are initially magnetically captured on magnetic beads by a generic tetraspanin antibody (e.g., CD9 or CD63) followed by the identification of disease-specific exosomes using cancer-related...

Major therapeutic advances have occurred over the last several years in the management of advanced ALK+ NSCLC patients. Crizotinib was the first agent approved for the management of ALK+ NSCLC patients after it demonstrated significantly greater clinical benefit compared to chemotherapy. Several next generation ALK inhibitors have demonstrated clinical benefit in patients with crizotinib refractory NSCLC patients including in the CNS. Based on available data, therapy with a next generation ALK inhibitor can be initiated following therapy with crizotinib without any assessment of the molecular mechanisms of resistance...

BACKGROUND: Treatments that target cancer stem cells play an important role in the controlling and eliminating of tumor initiation as well as in development, progression, and chemotherapy/radiotherapy resistance. In our previous study, we cultured and harvested human laryngeal cancer stem cells (CSCs) and applied microRNA biochips to screen differentially expressed miRNAs that were related to radiation tolerance in irradiated human laryngeal CSCs. According to the predicted genes and pathways of differential miRNAs target, down-regulated expression of hsa-miR-138-2-3p under radiation was thought to play a key role in enhancing the radio-sensitivity in human laryngeal squamous cancer stem cells...

There have been few reports on pediatric transfusion-associated circulatory overload (TACO). A 5-year-old boy with neuroblastoma underwent resection of the residual tumor. Because anemia progressed at the end of the operation, transfusion of red cell component was initiated. Ten minutes later, he suddenly developed hypoxemia, tachypnea, and tachycardia. Although elevated blood pressure and bilateral infiltrative shadows on chest X-rays were not observed, TACO was diagnosed based on positive balance during operation and N-terminal pro-brain natriuretic peptide elevation...

Genetic modification provides a means to enhancing disease resistance in animals. Toll-like receptor 4 (TLR4), a member of the TLR family, is critical for the recognition of lipopolysaccharide (LPS)/endotoxin from Gram-negative bacteria by host immune cells, which initiates cell activation and subsequently triggers a proinflammatory response to the invading pathogens. In this study, the first generation of genetically modified (GM) sheep overexpressing TLR4 was produced by microinjection for better disease resistance...

Mitotic rounding during cell division is critical for preventing daughter cells from inheriting an abnormal number of chromosomes, a condition that occurs frequently in cancer cells. Cells must significantly expand their apical area and transition from a polygonal to circular apical shape to achieve robust mitotic rounding in epithelial tissues, which is where most cancers initiate. However, how cells mechanically regulate robust mitotic rounding within packed tissues is unknown. Here, we analyze mitotic rounding using a newly developed multi-scale subcellular element computational model that is calibrated using experimental data...

Angiogenesis is important in tumorigenesis and tumor progression. Human vascular endothelial growth factor (hVEGF) is an angiogenic growth factor that plays a crucial role in tumor progression. The G-rich region within the 5'-untranslated region (5'-UTR) of hVEGF mRNA can form a 'switchable' RNA G-quadruplex structure that is essential for a cap-independent translation initiation. We screened our small-molecule library for binders of this G-tract. One novel quinazoline derivative, compound 1, showed a significant specific interaction with the G-tract and destabilized the G-quadruplex structure...

The DNA binding protein and chromatin structural regulator DEK regulates many cellular processes. These include proliferation, differentiation, apoptosis, senescence, DNA repairing and the maintenance of stem cell phenotype. DEK is increasingly recognized as a crucial player in many steps of cancer initiation and progression, and is precisely regulated by abundant promoting and inhibiting factors directly or indirectly. DEK may serve as an architectural modulating protein to regulate the expression and function of multiple human genes in cancer cells...

Indoleamine 2,3-dioxygenase (IDO1) plays a special role in the biology of various cancer types, because it breaks down the essential amino acid tryptophan for immune cell activation. Upregulation of IDO1 significantly correlates with the number of various T cell types in tumor tissues in melanoma and other cancers, suggesting that IDO expression is linked with effective and ineffective ('exhausted') immune response in cancer. Based on the reported IDO inhibitors (α-Methylated and indole-N-methylated tryptophan (Trp)), here we report the synthesis of potential IDO1 imaging agents through direct introduction of (18)F into the tryptophan aromatic ring...

Triple-negative breast cancer (TNBC) is a subtype of breast cancer with a poor prognosis, accounting for approximately 12-24% of breast cancer cases. Accumulating evidence has indicated that there is no effective targeted therapy available for TNBC. Dipalmitoylphosphatidic acid (DPPA) is a bioactive phospholipid. However, the function of DPPA in the growth of TNBC has not yet been studied. In this study, we employed TNBC cells and a subcutaneous tumor model to elucidate the possible effect of DPPA on tumor growth in TNBC...

Cancer stem cells or tumor-initiating cells (TICs) are a small subpopulation of cells that have the capacity to self-renew, differentiate and initiate tumors. These cells may function in tumor initiation, aggression and recurrence. Whether spheres derived from canine rhabdomyosarcoma cells have stem cell-like properties is unclear. We induced sphere formation in the canine rhabdomyosarcoma cell lines, CMS-C and CMS-J, and characterized the spheres in vitro and in vivo. Sphere-forming cells were more resistant to vincristine, mitoxantrone and doxorubicin than adherent cells...

Post-transcriptional regulation of gene expression by RNA binding proteins (RBPs) and non-coding RNAs plays an important role in global gene expression. Many post-transcriptional regulators are misexpressed and misregulated in cancers, resulting in altered programs of protein biosynthesis that can drive tumor progression. While comparative studies of several RBPs and microRNAs expressed in various cancer types have been reported, a model system that can be used to quantify RBP regulation and functional outcomes during the initiation and early stages of tumorigenesis is lacking...
