REVIEW
Kent W Mouw
Most bladder tumors have complex genomes characterized by a high mutation burden as well as frequent copy number alterations and chromosomal rearrangements. Alterations in DNA repair pathways-including the double-strand break (DSB) and nucleotide excision repair (NER) pathways-are present in bladder tumors and may contribute to genomic instability and drive the tumor phenotype. DNA damaging such as cisplatin, mitomycin C, and radiation are commonly used in the treatment of muscle-invasive or metastatic bladder cancer, and several recent studies have linked specific DNA repair pathway defects with sensitivity to DNA damaging-based therapy...

Neurotransmitters detection is critical to understanding communication between the brain and peripheral tissue. Serotonin is a key neurotransmitter linked to a number of conditions, but a full understanding of its role in disease is still lacking. The development of fast and selective serotonin detection platforms will provide researchers with tools to monitor serotonin in individuals before and after treatment for the condition of interest. Aptamer-gold nanoparticles conjugates that responded colorimetrically to serotonin with minimal response to its metabolite and other neurotransmitters were designed by simply adsorbing the DNA on the surface of AuNPs...

The recent advent of induced pluripotent stem cells has enabled the study of patient-specific and disease-related neurons in vitro and has facilitated new directions of inquiry into disease mechanisms. With these approaches, we now have the possibility of correlating ex vivo cellular phenotypes with individual patient response to treatment and/or side effects, which makes targeted treatments for schizophrenia and bipolar disorder a distinct prospect in the coming years. Here, we briefly review the current state of stem cell-based models and explore studies that are providing new insights into the disease biology of schizophrenia and bipolar disorder, which are laying the foundations for the development of novel targeted therapies...

REVIEW
C Elm'hadi, Z Es Sbai, M Reda Khmamouche, M Toreis, R Tanz, H Errihani, M Ichou
The appearance of meningeal carcinomatosis in breast cancer is an event that is being reported increasingly more frequently in the literature. It seems to be related with the lengthening of the patients' lives, improved sensitivity to diagnostic imaging and impermeability of the blood-brain barrier to the chemotherapeutic agents. It is an evolutionary form that affirms the metastatic invasion of the subarachnoidal space and is correlated with limited survival. Its diagnosis is difficult, due to the lack of specificity of the clinical signs dominated by headaches, cognitive disorders and possible signs and symptoms of progressive focal lesions...

Xiaobin Guo, Xiaoming Zhu, Limin Zhao, Xiao Li, Dongjun Cheng, Keqing Feng
Lung cancer, especially the non-small-cell lung cancer, is a highly aggressive vascular cancer with excessively activated signaling pathways. Tumor-associated calcium signal transducer 2, also known as trop2, was identified to be correlated with tumor proliferation and invasion of non-small-cell lung cancer; however, the biological role of trop2 in neovascularization of non-small-cell lung cancer remained elusive. In this study, we first verified that trop2 was overexpressed in non-small-cell lung cancer tissues as well as cell lines and that the increased expression of trop2 promoted non-small-cell lung cancer cell proliferation and invasion...

The incidence rate of intrahepatic cholangiocarcinoma is rising, and treatment options are limited. Therefore, new biological markers of intrahepatic cholangiocarcinoma are needed. Immunohistochemistry and enzyme-linked immunosorbent assay were applied to analyze the expressions of CD97, CD55, and soluble CD97 in 71 patients with intrahepatic cholangiocarcinoma and 10 patients with hepatolithiasis. CD97 and CD55 were not expressed in hepatolithiatic tissues, but positive expression was observed in 76.1% (54/71) and 70...

Radiotherapy is an important treatment option for non-small cell lung carcinoma patients. Despite the appropriate use of radiotherapy, radioresistance is a biological behavior of cancer cells that limits the efficacy of this treatment. Deregulation of microRNAs contributes to the molecular mechanism underlying resistance to radiotherapy in cancer cells. Although the functional roles of microRNAs have been well described in lung cancer, their functional roles in radioresistance are largely unclear. In this study, we established a non-small cell lung carcinoma Calu-1 radioresistant cell line by continuous exposure to therapeutic doses of ionizing radiation as a model to investigate radioresistance-associated microRNAs...

Oral and intestinal mucositis is a debilitating side effect of radiation treatment. A mouse model of radiation-induced mucositis leads to weight loss and tissue damage, reflecting the human ailment as it responds to keratinocyte growth factor (KGF), the standard-of-care treatment. Cultured intestinal crypt organoids allowed the development of an assay monitoring the effect of treatments of intestinal epithelium to radiation-induced damage. This in vitro assay resembles the mouse model as KGF and roof plate-specific spondin-1 (RSPO1) enhanced crypt organoid recovery following radiation...

Carotenoids are the main tomato components, especially lycopene. Lycopene is more bioavailable in tomato processed products than in raw tomatos, since formation of lycopene cis-isomers during food processing and storage may increase its biological activity. In the current study, we evaluated the influence of lycopene extracts (5 mg / mL) from different tomato-based food products (paste, sauce, extract and ketchup) on cell viability and apoptosis on primary human prostate cancer cells (PCa cels) for 96h. Using MTT assay, we observed a significant decrease on primary PCa cell viability upon treatment with lycopene extracted from either 4 tomato-based food products...

Tumor-infiltrating lymphocytes (TILs) may represent a viable source of T cells for the biological treatment of patients with gliomas. Glioma tissue was obtained from 16 patients, tumor cell lines were established, and TILs were expanded in 16/16 cases using a combination of IL-2/IL-15/IL-21. Intracellular cytokine staining (ICS, IL-2, IL-17, TNFα and IFNγ production) as well as a cytotoxicity assay was used to detect TIL reactivity against autologous tumor cells or shared tumor-associated antigens (TAAs; i...

While early treatment of primary prostate cancer is very effective, the incidence of primary prostate cancer continues to rise and therefore the detection of men with high-risk non-metastatic prostate cancer and their subsequent management is becoming increasingly important. There continues to be no molecularly-targeted or chemotherapeutic options with proven, statistically significant survival benefit in this setting. However, there are indications that further risk stratification using molecular features could potentially help distinguish indolent from aggressive prostate cancer, ultimately providing biological markers that could guide a more personalised approach to therapy selection...

Discovery of sensitizing mutations in epidermal growth factor receptor (EGFR) and the subsequent development of EGFR tyrosine kinase inhibitors (TKIs) have substantially changed the treatment of lung cancer. First-line treatment with EGFR TKIs (gefitinib, erlotinib and afatinib) has demonstrated a superior response rate and progression-free survival (PFS) compared with chemotherapy in EGFR-mutation positive patients. However, a number of open questions remain, such as choice between the three EGFR TKIs licensed, treatment of patients unsuitable for chemotherapy due to morbidity or advanced age, management of acquired resistance and optimal biological sample to determine EGFR status...
