and rearrangements may coexist in the same tumor. rearrangements and loss are concomitant events in prostate cancer (PrCa), and can cooperate in progression. We have reported that mRNA expression of and rearrangements plus loss define an aggressive tumor subset.

Although problem-based learning (PBL) has been used for over 40 years, with many studies comparing the benefits of PBL versus other educational approaches, little attention has been paid to the effectiveness of hybrid PBL (H-PBL) curricula. Here we aimed to compare the learning outcomes of two groups of undergraduate biology students working towards a bachelor's degree: one group used an H-PBL approach, while the second used a lecture-based learning (LBL) approach. Specifically, the H-PBL group used a PBL module with interdisciplinary problems, which represented 20% of the entire curriculum.

The TMPRSS2-ERG fusion has been reported in 42 to 78% of prostate tumors. More than 90% of ERG-overexpressing tumors harbor the fusion. The relationship between the TMPRSS2-ERG fusion and prognosis is controversial.

The main challenge for clinical management of prostate cancer is to distinguish tumors that will progress faster and will show a higher tendency to recur from the more indolent ones. We have compared expression profiles of 18 prostate cancer samples (seven with a Gleason score of 6, eight with a Gleason score of 7, and three with a Gleason score of ≥8) and five nonneoplastic prostate samples, using the Affymetrix Human Array GeneChip Exon 1.0 ST.

Article Synopsis
  • The PI3K-AKT signaling pathway is frequently altered in bladder cancer, with FGFR3 mutations commonly found in low-grade tumors and RAS gene mutations occurring in about 13% of cases.
  • Some bladder tumors have multiple mutations in PI3K-AKT or RAS-MAPK pathway genes, though certain pairs of mutations cannot occur together.
  • The study found high levels of phosphorylated AKT (pAKT) and ERK1/2 (pERK1/2) in the tumors, particularly in those with FGFR3 and PIK3CA mutations, suggesting potential links between specific mutations and the aggressiveness of bladder cancer.

The phosphatidylinositol 3-kinase (PI3K)-AKT and RAS-MAPK pathways are deregulated in a wide range of human cancers by gain or loss of function in several of their components. Our purpose has been to identify genetic alterations in members of these pathways in prostate cancer. A total of 102 prostate tumors, 79 from prostate cancer alone (group G1) and 23 from bladder and prostate cancer patients (G2), are the subject of this study.

Prostate cancer is the second cause of cancer-related death in men of the Western world. The potential prognostic role of the combined alterations in EGFR and PTEN in prostate cancer is not well established. It was the aim of the study to investigate this role.

Prostate cancer is the second cause of cancer-related death in men of the Western World. The role of FGFR3 and its abnormalities in prostate cancer are not known. FGFR3 mutations have been reported in some human tumors.

Krüppel-like factor 6 (KLF6) has been reported to act as a tumor suppressor gene involved in the regulation of the cell cycle by activating p21 in a p53-independent manner. Many studies suggest that KLF6 is inactivated by allelic loss and somatic mutation. However, there is a high variability in the reported frequency of mutations (from 1 to 55%).
