Over the past decade, deep molecular analysis has revealed that many cancers, including glioblastomas (GBMs), can be subdivided in several subtypes according to genetic and/or transcriptomal similarity. These subtype classifications have given significant insight into tumor biology and provided encouragement for targeted therapeutic strategies. In fact, molecular target therapies have conferred...

While advanced melanoma remains one of the most challenging cancers, recent developments in our understanding of the molecular drivers of this disease have uncovered exciting opportunities to guide personalized therapeutic decisions. Genetic analyses of melanoma have uncovered several key molecular pathways that are involved in disease onset and progression, as well as prognosis. These advances...

We provided a cross-tissue comparative analysis of between-subtype molecular commonality for ovarian cancer, breast cancer, hepatocellular carcinoma, glioma, lung squamous carcinoma and nasopharyngeal carcinoma. Our analysis showed that molecular subtypes with similar phenotype or similar clinical outcome could be correlated by their transcriptional profile and pathway profile. Pathway dysregul...

Epithelial ovarian cancer represents the most lethal gynecological malignancy in the developed world, and can be divided into five main histological subtypes: high grade serous, endometrioid, clear cell, mucinous and low grade serous. These subtypes represent distinct disease entities, both clinically and at the molecular level. Molecular analysis has revealed significant genetic heterogeneity ...

Background: Breast carcinoma (BC) is a heterogeneous disease due to its different molecular profiles i.e. luminal (luminal A and luminal B) and non-luminal (HER2 positive and triple negative) subtypes. Prognostic value of clinicopathological factors of Indonesian BC of different molecular subtypes has never been reported previously. This study aims to elaborate prognostic impacts on Indonesian ...

BACKGROUND Reverse phase protein array (RPPA) analysis, allows investigation of potential targets at the functional protein level,. We identified TNBC subtypes at the protein level using RPPA and compared them with mRNA molecular subtypes (TNBCtype, TNBCtype-4, and PAM50) that is unique in its availability of both RPPA and mRNA analyses. METHODS We classified the samples from 80 TNBC patients...

BACKGROUND We performed a retrospective study to assess whether the initial molecular characteristics of glioblastomas (GBMs) were associated with the response to the bevacizumab/irinotecan chemotherapy regimen given at recurrence. RESULTS Comparison of the genomic and gene expression profiles of the responders (n = 12) and nonresponders (n = 13) demonstrated only slight differences and could...

OBJECTIVES To determine the distribution of various molecular subtypes of breast cancer in Saudi Arabia and to assess the association between these subtypes and age at diagnosis, tumor size, histopathological type, grade, presence of carcinoma in-situ, and lymph node status.  METHODS This observational retrospective study, between January 2010 and  December 2014, was conducted at King Khalid ...

Rate heterogeneity among lineages is a common feature of molecular evolution, and it has long impeded our ability to accurately estimate the age of evolutionary divergence events. The development of relaxed molecular clocks, which model variable substitution rates among lineages, was intended to rectify this problem. Major subtypes of pandemic HIV-1 group M are thought to exemplify closely rela...
