Massive evolution of the immunoglobulin heavy chain locus in children with B precursor acute lymphoblastic leukemia.

open access: yesBlood, 2012
The ability to distinguish clonal B-cell populations based on the sequence of their rearranged immunoglobulin heavy chain (IgH) locus is an important tool for diagnosing B-cell neoplasms and monitoring treatment response.

Targeting the MDM2‐MDM4 interaction interface reveals an otherwise therapeutically active wild‐type p53 in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.

VH replacement in rearranged immunoglobulin genes [PDF]

open access: yes, 2005
Examples suggesting that all or part of the V<sub>H</sub> segment of a rearranged V<sub>H</sub>DJ<sub>H</sub> may be replaced by all or part of another V<sub>H</sub> have been appearing since the 1980s ...

The immunoglobulin heavy chain locus in the platypus (Ornithorhynchus anatinus)

open access: yesMolecular Immunology, 2009
Immunoglobulins loci in mammals are well known to be organized within a translocon, however their origin remains unresolved. Four of the five classes of immunoglobulins described in humans and rodents (immunoglobulins M, G, E and A-IgM, IgG, IgE and IgA) were found in marsupials and monotremes (immunoglobulin D-IgD was not found) thus showing that the ...

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

RAGs and Regulation of Autoantibodies [PDF]

open access: yes, 2004
Autoreactive antibodies are etiologic agents in a number of autoimmune diseases. Like all other antibodies these antibodies are produced in developing B cells by V(D)J recombination in the bone marrow.

The immunoglobulin heavy chain locus in the reptile Anolis carolinensis

open access: yesMolecular Immunology, 2009
We describe the entire immunoglobulin heavy chain (IgH) locus from the reptile Anolis carolinensis. The heavy chain constant (C(H)) region includes C mu, C delta and C upsilon genes. This is the first description of a C upsilon gene in the reptilian class. Variable (V(H)), diversity (D(H)) and joining (J(H)) genes are located 5' from the constant (C(H))

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Two Cases of Heavy Chain MGUS

open access: yesCase Reports in Oncological Medicine, 2016
Heavy chain diseases are rare variants of B-cell lymphomas that produce one of three classes of immunoglobulin heavy chains, without corresponding light chains. We describe two patients with asymptomatic heavy chain monoclonal gammopathy.

Functional immunoglobulin transgenes guide ordered B-cell differentiation in Rag-1-deficient mice [PDF]

open access: yes, 1994
We have examined the regulatory role of the individual components of the immunoglobulin antigen receptor in B-cell development by transgenic complementation of Rag-1 deficient (Rag-1⁻) mice. Complementation with a membrane µ heavy chain (µHC) gene allows
