- Ibrutinib and acalabrutinib are first- and next-generation Bruton Tyrosine Kinase inhibitors (BTKi), respectively, approved for chronic lymphocytic leukemia (CLL). Ibrutinib has been associated with cardiovascular events, including atrial fibrillation (AF) and hypertension. Acalabrutinib has demonstrated non-inferior progression-free survival than ibrutinib in relapsed/refractory CLL patients, with a lower cardiovascular event incidence. These adverse events seem to be derived from off-targets rather than BTK inhibition. Machine learning algorithms were applied to identify targets likely to trigger AF and hypertension in simulated CLL patients receiving acalabrutinib or ibrutinib. Common ibrutinib and acalabrutinib off-targets showed association with AF through structural remodeling and electrophysiology/ectopic activity mechanisms (TEC and ERBB4). There was association with hypertension through inflammation (ERBB4) and oxidative stress and endothelial dysfunction (ERBB4 and RIPK2). Ibrutinib-specific off-targets showed association with AF through structural remodeling (HCK, FGR, LYN, FYN, YES1, and FLT3) and electrophysiology activity (LYN and SRC), and with hypertension through inflammation (LCK, JAK3, and FLT3) and oxidative stress and endothelial dysfunction (ERBB2, BLK, SRC, and CSK). No acalabrutinib-specific off-targets were identified for AF or hypertension. This study supports that BTKi off-target selectivity may justify the different AF and hypertension incidences, suggesting their association with several ibrutinib-specific off-targets and identifying no acalabrutinib-specific ones. - Source: PubMed

Córdoba RaúlBayés-Genís AntoniMuntañola AnaColomer DolorsCastro JorgeLeiva CarolinaÁlvarez EstherZatarain-Nicolas Eduardo - This study aimed to identify genetic variants using a customized next-generation sequencing (NGS) panel for pediatric myelodysplastic syndrome (pMDS) and to explore their associations with cytogenetic and clinical characteristics. Cytogenetic analyses were conducted using G-banding and fluorescence in situ hybridization. NGS was performed with the Ion Torrent Personal Genome Machine for the following genes: , , , , , , , , , , , , , , and . Analyses were performed with Ion Reporter 5.20.8.0 software. Genetic variants were classified using the dbSNP, 1000 Genomes, COSMIC, and Varsome databases. We analyzed 25 cases of pMDS; 15 presented abnormal karyotypes, and 19 showed genetic variants. Among the 29 variants identified across 12/15 genes, 27% were pathogenic and 14% were likely pathogenic, with and most frequently associated with disease progression. A new somatic variant of uncertain significance in was detected in seven patients showing heterogeneous clinical outcomes. Genetic variants were found in 7/10 patients with normal karyotypes, indicating that submicroscopic alterations can shed light on disease biology. Our results highlight the critical role of a targeted NGS panel in identifying molecular alterations associated with pMDS pathogenesis, thereby enhancing diagnostic precision, prognosis, and aiding in treatment selection. - Source: PubMed

Lovatel Viviane LamimFerreira Gerson Mourada Silva Beatriz Ferreirade Souza Torres Rayanede Cássia Barbosa da Silva Tavares RitaBueno Ana Paula SilvaAbdelhay Elianade Souza Fernandez Teresa - We performed the next-generation sequencing (NGS) analysis of a rare grade 1 brain meningioma (angiomatous type) and a common grade 1 spinal meningioma (psammomatous type) and compared their mutation profiling. The data were analysed using the Ion Reporter 5.16 programme (Thermo Fisher Scientific, Waltham, MA). Sequencing analysis identified 10 novel variants and two previously reported variants that were common between these two tumours. Nine variants were missense, which included an insertion in EGFR c.1819_1820insCA, causing frameshifting, and a single nucleotide deletion in HRAS and HNF1A genes, causing frameshifting in these genes. These were common variants identified for both tumours. Also, 10 synonymous variants and 10 intronic variants were common between these two tumours. In intronic variants, two were splice site_5' variants (acceptor site variants). Typical of the angiomatous type tumour, there were 11 novel and six previously reported variants that were not found in the psammomatous tumour; three variants were synonymous, 11 were missense mutations, and three were deletions causing frameshifting. The deletion variants were in the SMARCB1, CDH1, and KDR genes. In contrast, eight novel and five previously reported variants were found in the psammomatous meningioma tumour. In this tumour, two variants were synonymous: a deletion causing a frameshifting in [(c.3920delT; p. (Ile1307fs)], and a two-base pair insertion and deletion (INDEL) [(c.3986_3987delACinsGT; p. (His1329Arg)] both in the APC gene were also found. Among our findings, we have identified that ALK, VHL, CTNNB1, EGFR, ERBB4, PDGFRA, KDR, SMO, ABL1, HRAS, ATM, HNF1A, FLT3, and RB1 mutations are common for psammomatous meningioma and angiomatous tumours. Variants typical for angiomatous (brain) meningioma are PIK3CA, KIT, PTPN11, CDH1, SMAD4, and SMARCB1; the variants typical for psammomatous meningioma are APC, FGFR2, HNF1A, STK11, and JAK3. The RET splice variant (c.1880-2A>C) found in both meningioma tumours is reported (rs193922699) as likely pathogenic in the Single Nucleotide Polymorphism Database (dbSNP). All missense variants detected in these two meningiomas are found in the cancer-driver genes. The eight variants we found in genes such as EGFR, PDGFRA, SMO, FLT3, PIK3CA, PTPN11, CDH1, and RB1 are glioma-driver genes. We did not find any mutations in genes such as BRAF, IDH1, CDKN2A, PTEN, and TP53, which are also listed as cancer-driver genes in gliomas. Mutation profiling utilising NGS technology in meningiomas could help in the accurate diagnosis and classification of these tumours and also in developing more effective treatments. - Source: PubMed

Taher Mohiuddin MAshour Khalid MAlthaqafi Bashayer AMansouri AlbatoolAl-Harbi Arwa AFilfilan WeamBakhsh Ghassan YBantan Najwa ASaeed MuhammadAlQuthami Khalid - The prognosis of acute lymphoblastic leukemia (ALL) in adolescents and adults is poor, and recurrence is an important cause of their death. Changes of genetic information play a vital role in the pathogenesis and recurrence of ALL; however, the impact of molecular genetic mutations on disease diagnosis and prognosis remains unexplored. This study aimed to explore the frequency spectrum of gene mutations and their prognostic significance, along with the minimal residual disease (MRD) level and hematopoietic stem cell transplantation (HSCT), in adolescent and adult patients aged ≥15 years with ALL. - Source: PubMed

Sun XueLiu XiaoqianLi YingShi XueLi YahanTan RanJiang YujieSui XiaohuiGe XuelingXu HongzhiWang XinFang Xiaosheng - Dual inhibitors of JAK2 and FLT3 can synergistically control the development of acute myeloid leukemia (AML), and overcome secondary drug resistance of AML that is associated with FLT3 inhibition. We therefore designed and synthesized a series of 4-piperazinyl-2-aminopyrimidines as dual inhibitors of JAK2 and FLT3, and improved their selectivity for JAK2. Screening cascades revealed that compound 11r exhibited inhibitory activity with IC values of 2.01, 0.51, and 104.40 nM against JAK2, FLT3, and JAK3, respectively. Compound 11r achieved a high selectivity for JAK2 at a ratio of 51.94, and also showed potent antiproliferative activity in HEL (IC = 1.10 μM) and MV4-11 (IC = 9.43 nM) cell lines. In an in vitro metabolism assay, 11r exhibited moderate stability in human liver microsomes (HLMs), with a half-life time of 44.4 min, and in rat liver microsomes (RLMs), with a half-life of 143 min. In pharmacokinetic studies, compound 11r showed moderate absorption (Tmax = 5.33 h), with a peak concentration of 38.7 ng/mL and an AUC of 522 ng h/mL in rats, and an oral bioavailability of 25.2%. In addition, 11r induced MV4-11 cell apoptosis in a dose-dependent manner. These results indicate that 11r is a promising selective JAK2/FLT3 dual inhibitor. - Source: PubMed
