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

Jornal 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.

Chromosomal rearrangements as a source of new gene formation in Drosophila yakuba [PDF]

arXiv, 2018
The origins of new genes are among the most fundamental questions in evolutionary biology. Our understanding of the ways that new genetic material appears and how that genetic material shapes population variation remains incomplete. De novo genes and duplicate genes are a key source of new genetic material on which selection acts.

Defective development of gamma/delta T cells in interleukin 7 receptor-deficient mice is due to impaired expression of T cell receptor gamma genes. [PDF]

, 1999
Mice lacking the interleukin 7 receptor (IL-7R) generate alpha/beta T cells at a detectable but greatly reduced rate, but gamma/delta T cells are completely absent.

BCR-ABL1 gene rearrangement as a subclonal change in ETV6-RUNX1–positive B-cell acute lymphoblastic leukemia

Blood Advances, 2016
: We report here on a case of ETV6-RUNX1–positive B-cell acute lymphoblastic leukemia (B-ALL) that has acquired a BCR-ABL1 gene rearrangement as a subclonal change.

Impact of Salmonella genome rearrangement on gene expression

Evolution Letters, 2022
In addition to nucleotide variation, many bacteria also undergo changes at a much larger scale via rearrangement of their genome structure (GS) around long repeat sequences.

The Mitochondrial Genome of Paraminabea aldersladei (Cnidaria: Anthozoa: Octocorallia) Supports Intramolecular Recombination as the Primary Mechanism of Gene Rearrangement in Octocoral Mitochondrial Genomes

Genome Biology and Evolution, 2012
Sequencing of the complete mitochondrial genome of the soft coral Paraminabea aldersladei (Alcyoniidae) revealed a unique gene order, the fifth mt gene arrangement now known within the cnidarian subclass Octocorallia.

Mechanisms of gene rearrangement in 13 bothids based on comparison with a newly completed mitogenome of the threespot flounder, Grammatobothus polyophthalmus (Pleuronectiformes: Bothidae)

BMC Genomics, 2019
Background The mitogenomes of 12 teleost fish of the bothid family (order Pleuronectiformes) indicated that the genomic-scale rearrangements characterized in previous work.

Lateral Gene Transfer, Rearrangement and Reconciliation [PDF]

arXiv, 2013
Background. Models of ancestral gene order reconstruction have progressively integrated different evolutionary patterns and processes such as unequal gene content, gene duplications, and implicitly sequence evolution via reconciled gene trees. In unicellular organisms, these models have so far ignored lateral gene transfer, even though it can have an

A practical algorithmic approach to mature aggressive B cell lymphoma diagnosis in the double/triple hit era. Selecting cases, matching clinical benefit. A position paper from the Italian Group of Haematopathology (G.I.E.) [PDF]

, 2019
An accurate diagnosis of clinically distinct subgroups of aggressive mature B cell lymphomas is crucial for the choice of proper treatment. Presently, precise recognition of these disorders relies on the combination of morphological, immunophenotypical ...
