A Review of the Histologic, Genetic and Molecular Characteristics of Meningioma Pathogenesis and Progression

Aug 2017 DOI 10.14302/issn.2572-3030.jcgb-14-383
Adrian MaurerCorresponding author

Meningiomas are the most common intracranial tumor in humans. The heterogeneity of these tumors lends difficulty to the genetic, epigenetic, and molecular changes that occur in meningioma pathogenesis, progression, and recurrence. Current de facto classification schemes are based on histologic evalu…

Combination of Radiation Therapy and Immunotherapy in the Treatment of Melanoma

Apr 2017 DOI 10.14302/issn.2372-6601.jhor-17-1463
Sylwia SzablewskaCorresponding author

Melanoma is considered to be a very aggressive cancer due to its rapid growth, early and multiple metastases and limited response to standard treatment. Many researchers have hypothesized that the combination of radiation therapy and immunotherapy in the treatment of melanoma primary tumors and meta…

José V. RoigCorresponding author

Aim: To analyze the factors involved in and the results of stoma reversal after an emergency Hartmann's operation. Methods: A multicenter retrospective study from the Valencian Society of Surgery of patients who had undergone an emergent Hartmann’s operation from 2004 to 2008. An analysis of the rev…

Cytoplasmic Retention of CDC6 Induces Premature Senescence in Immortalized Cells and Suppresses Tumor Formation in Mice

Jun 2016 DOI 10.14302/issn.2372-6601.jhor-16-1125
Jun-ya KatoCorresponding author

Senescence is a powerful mechanism that prevents the development of tumors in vivo; however, once tumors are formed, most are refractory to senescence in response to oncogenic stress. Therefore, a novel pathway leading to senescence is required. We herein demonstrated that the cell cycle regulator C…
