Co-polysomy of 1p/19q in glial tumors: Retrospective analysis of 221 cases from single center.

Glial tumors are malignant brain tumors that arise from glial cells of brain or spine and have genetic aberrations in their genome. 1p/19q co-deletion is associated with increased Overall Survival (OS) time with enhanced response to chemo- and radio-therapy in oligodendrogliomas. However, prognostic significance of 1p/19q co-polysomy is still unclear.

MicroRNA expression profiling reveals the potential function of microRNA-31 in chordomas.

Chordomas are rare bone tumors arising from remnants of the notochord. Molecular studies to determine the pathways involved in their pathogenesis and develop better treatments are limited. Alterations in microRNAs (miRNAs) play important roles in cancer.

Differentiation and neuro-protective properties of immortalized human tooth germ stem cells.

Stem cells are considered to be promising therapeutic options in many neuro-degenerative diseases and injuries to the central nervous system, including brain ischemia and spinal cord trauma. Apart from the gold standard embryonic and mesenchymal origin, human tooth germ stem cells (hTGSCs) have also been shown to enjoy the characteristics of mesenchymal stem cells (MSCs) and the ability to differentiate into adipo-, chondro-, osteo- and neuro-genic cells, suggesting that they might serve as potential alternatives in the cellular therapy of various maladies. Immortalization of stem cells may be useful to avoid senescence of stem cells and to increase their proliferation potential without altering their natural characteristics.
