Virus-transformed pre-B cells show ordered activation but not inactivation of immunoglobulin gene rearrangement and transcription [PDF]

open access: yes, 1991
Virus-transformed pre-B cells undergo ordered immunoglobulin (Ig) gene rearrangements during culture. We devised a series of highly sensitive polymerase chain reaction assays for Ig gene rearrangement and unrearranged Ig gene segment transcription to ...

Insights into the Evolution of Aphid Mitogenome Features from New Data and Comparative Analysis

open access: yesAnimals, 2022
The complete mitochondrial genomes and their rearrangement patterns can provide useful information for inferring evolutionary history of organisms. Aphids are one of the insect groups with some unique mitogenome features.

A method for computing an inventory of metazoan mitochondrial gene order rearrangements

open access: yesBMC Bioinformatics, 2011
Background Changes in the order of mitochondrial genes are a good source of information for phylogenetic investigations. Phylogenetic hypotheses are often supported by parsimonious mitochondrial gene order rearrangement scenarios. CREx is a heuristic for

Prevalence and Clinical Impact of Concomitant Mutations in Anaplastic Lymphoma Kinase Rearrangement Advanced Non-small-Cell Lung Cancer (Guangdong Association of Thoracic Oncology Study 1055)

open access: yesFrontiers in Oncology, 2020
Background: In patients with anaplastic lymphoma kinase (ALK) rearrangement-positive advanced non–small-cell lung cancer (NSCLC), ALK inhibitors are now the standard treatment, but their clinical efficacy varies widely for each patient.

Pre-B-cell acute lymphoblastic leukemia with bulk extramedullary disease and chromosome 22 (EWSR1) rearrangement masquerading as Ewing sarcoma [PDF]

open access: yes, 2010
We report a 2-year-old female with a subcutaneous tumor who was initially misdiagnosed as suffering from Ewing sarcoma with a positive EWSR1 rearrangement and EWS/FLI1 transcript.

A new transcript in the TCRB locus unveils the human ortholog of the mouse pre-Dß1 promoter [PDF]

open access: yes, 2017
Introduction: While most transcripts arising from the human T Cell Receptor locus reflect fully rearranged genes, several germline transcripts have been identified. We describe a new germline transcript arising from the human TCRB locus.

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

open access: yesBlood 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.

The Prevalence of the EML4-ALK Fusion Gene in Cytology Specimens from Patients with Lung Adenocarcinoma

open access: yesPulmonary Medicine, 2020
Background. Under the National Comprehensive Cancer Network (NCCN) guidelines for non-small-cell lung carcinoma (NSCLC), anaplastic lymphoma kinase (ALK) gene rearrangement is required to be assessed.

Programmed Gene Rearrangements Altering Gene Expression

open access: yesScience, 1987
Programmed gene rearrangements are used in nature to alter gene copy number (gene amplification and deletion), to create diversity by reassorting gene segments (as in the formation of mammalian immunoglobulin genes), or to control the expression of a set of genes that code for the same function (such as surface antigens).

Molecular testing for the clinical diagnosis of fibrolamellar carcinoma. [PDF]

open access: yes, 2018
Fibrolamellar carcinoma has a distinctive morphology and immunophenotype, including cytokeratin 7 and CD68 co-expression. Despite the distinct findings, accurate diagnosis of fibrolamellar carcinoma continues to be a challenge.
