Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol. Rnd proteins are atypical ...

Retinoblastoma is the most common primary intra-ocular tumor in childhood. It has been established that recurrent cytogenetic abnormalities are the hallmark of mostly all malignant tumors. Recurrent atypical cytogenetic ...

Anomalies of constitutional karyotype, which have led to the discovery of oncogenes and tumor-suppressor genes in embryonal tumors such as retinoblastoma and Wilms tumor, have, until recently, rarely been reported until ...

BACKGROUND: Adolescents with cancer are enrolled in clinical trials at far lower rates than children. This report compares the number of adolescents (15-19-year-olds) and children (0-14-year-olds) enrolled in the protocols ...

Protein kinases are activated by phosphorylation and by the binding of activator proteins. The interplay of these two factors is incompletely understood. We applied energetic analysis to this question and characterized the ...

INTRODUCTION: Optimal management of soft tissue sarcoma (STS) remains a challenge. A nationwide survey assessed the quality of STS care in the Netherlands, thereby aiming to identify potentialities for improvement through ...

MRI-detected extramural venous invasion (mrEMVI) is a poor prognostic factor in rectal cancer. Pre-operative chemoradiotherapy (CRT) can cause regression in the severity of EMVI and subsequently improve survival whereas ...

BACKGROUND AND AIM: REGARD and RAINBOW were global, phase 3, randomized, double-blind trials of second-line ramucirumab for metastatic gastric or gastroesophageal junction adenocarcinoma. Exploratory subgroup analyses were ...
