Extensive gene rearrangements in the mitochondrial genomes of two egg parasitoids, Trichogramma japonicum and Trichogramma ostriniae (Hymenoptera: Chalcidoidea: Trichogrammatidae)

open access: yesScientific Reports, 2018
Animal mitochondrial genomes usually exhibit conserved gene arrangement across major lineages, while those in the Hymenoptera are known to possess frequent rearrangements, as are those of several other orders of insects.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Suppressible and nonsuppressible autocrine mast cell tumors are distinguished by insertion of an endogenous retroviral element (IAP) into the interleukin 3 gene [PDF]

open access: yes, 1993
After v-H-ras expression, the interleukin 3 (IL-3)-dependent PB-3c mast cells progress in vivo to two different classes of IL-3 autocrine tumors. Class I tumors show a germline configuration of the IL-3 gene and represent more than 90% of tumors analyzed

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10

open access: yesFEBS Open Bio, EarlyView.
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

Prokaryotic metallothionein locus and cadmium tolerance in Synechococcus PCC 6301 [PDF]

open access: yes, 1992
The aim of this study was to investigate the molecular mechanism of Cd-tolerance in the cyanobacterium Synechococcus PCC 6301 and to establish whether the prokaryotic metallothionein (MT) locus, smt, is involved.

Immunohistochemical and Molecular Characterization of Endometrial Stromal Sarcomas

open access: yesClinical Pathology, 2020
Introduction: Endometrial stromal sarcomas (ESSs) are rare and characterized by translocations t(7;17)(p15;q11.2) and t(10;17)(q22;p13), resulting in JAZF1-SUZ12 and YWHAE-FAM22 gene fusions used for defining low-grade (LG-ESS) and high-grade (HG-ESS ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Gene Rearrangement and Molecular Evolution in Animal Mitochondrial Genomes

open access: yes, 2005
Phylogenetic analysis of gene order data is a developing area, and many questions on gene orders are still unresolved. In this project, we started from the OGRe database, where we obtained the mitochondrial genome information (after some corrections),

Imunofenotipagem e rearranjo gênico em doenças pulmonares linfocíticas e linfoproliferativas Immunophenotyping and gene rearrangement analysis in lymphoid/lymphoproliferative disorders of the lungs

open access: yesJornal Brasileiro de Pneumologia, 2007
OBJETIVO: Determinar a utilidade, na prática rotineira, da análise da clonalidade dos linfócitos T e B nos tecidos pulmonares por reação em cadeia da polimerase no diagnóstico das doenças linfoproliferativas pulmonares.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

open access: yesAging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.
