Abstract Hairy cell leukemia (HCL) is an uncommon mature B-cell malignancy characterized by a typical morphology, immunophenotype, and clinical profile. The vast majority of HCL patients harbor the canonical BRAF V600E mutation which has become a rationalized target of the subsequently deregulated RAS-RAF-MEK-MAPK signaling pathway in HCL patients who have relapsed or who are refractory to front-line therapy. However, several HCL patients with a classical phenotype display non-canonical BRAF mutations or rearrangements. These include sequence variants within alternative exons and an oncogenic fusion with the IGH gene. Care must be taken in the molecular diagnostic work-up of patients More >

Abstract Objectives: Treatment of metastatic colorectal cancer (mCRC) includes resection of liver metastases (LM), however, no validated biomarker identifies patients most likely to benefit from this procedure. This meta-analysis aimed to assess the impact of the most relevant molecular alterations in cancer-related genes of CRC (i.e., RAS, BRAF, SMAD4, PIK3CA) as prognostic markers of survival and disease recurrence in patients with mCRC surgically treated by LM resection. Methods: A systematic literature review was performed to identify studies reporting data regarding survival and/or recurrence in patients that underwent complete liver resection for CRC LM, stratified according to… More > Graphic Abstract

Abstract Previous studies have shown that PRDX5 and Nrf2 are antioxidant proteins related to abnormal reactive oxidative species (ROS). PRDX5 and Nrf2 play a critical role in the progression of inflammations and tumors. The combination of PRDX5 and Nrf2 was examined by Co-immunoprecipitation, western blotting and Immunohistochemistry. H₂O₂ was applied to affect the production of ROS and induced multi-resistant protein 1 (MRP1) expression in NSCLC cells. The zebrafish models mainly investigated the synergistic effects of PRDX5 and Nrf2 on lung cancer drug resistance under oxidative stress. We showed that PRDX5 and Nrf2 form a complex and significantly More >

Abstract La leucémie à tricholeucocytes (LT) représente 2% de l’ensemble des leucémies. Le diagnostic repose sur la présence dans le sang et/ou la moelle de tricholeucocytes: cellules lymphoïdes B au cytoplasme chevelu exprimant le CD103, CD123, CD11c et CD25. La mutation BRAF^V600E, marqueur moléculaire de la maladie, est présente dans plus de 80% des cas. La LT doit être distinguée des autres syndromes lymphoprolifératifs chroniques B, notamment des autres proliférations à cellules chevelues, forme variante de la leucémie à tricholeucocytes (LT-V) et lymphome splé- nique diffus de la pulpe rouge (LSDPR). Des progrès thérapeutiques ont été récemment… More >

Abstract Malignant melanoma is characterized by both genetic and molecular alterations that activate phosphoinositide 3-kinase (PI3K), and RAS/BRAF pathways. In this work, through diversity-based high-throughput virtual screening we identified a lead molecule that selectively targets PI3K and BRAF^V600E kinases. Computational screening, Molecular dynamics simulation and MMPBSA calculations were performed. PI3K and BRAF^V600E kinase inhibition was done. A375 and G-361 cells were used for in vitro cellular analysis to determine antiproliferative effects, annexin V binding, nuclear fragmentation and cell cycle analysis. Computational screening of small molecules indicates compound CB-006-3 selectively targets PI3KCG (gamma subunit), PI3KCD (delta subunit) and BRAF^V600E. Molecular… More >

Abstract Advances in technology are enabling gene mutations in papillary thyroid carcinoma (PTC) to be analyzed and clinical outcomes, such as recurrence, to be predicted. To date, the most common genetic mutation in PTC is in BRAF kinase (BRAF). However, whether mutations in other genes coincide with those in BRAF remains to be clarified. The aim of this study was to find mutations in other genes that co-exist with mutated BRAF, and to analyze their frequency and clinical relevance in PTC. Clinical and genetic data were collected from 213 PTC patients with a total of 36,572… More >

Abstract Research in microgravity is of utmost importance for disclosing the impact of gravity on biological processes and organisms. With the development of space technology, scientists pay more attention to cardiovascular diseases associated with microgravity. However, up to date only sparse data exist on microgravity and cardiovascular development mechanisms. In this study, zebrafish was chosen as the model organism. Zebrafish embryos were exposed to microgravity using a ground-based simulation microgravity (SM) bioreactor. The effects of SM on the development of early embryonic vascular system were studied in vivo in real-time. Zebrafish embryos were selected and divided… More >
