[Hematologic malignancies of the breast].

Hematolymphoid tumors of the breast are uncommon. They either represent a secondary site of a known hematological malignancy or a primary disease (sometimes linked to systemic treatment such as chemotherapy for other cancers). The majority of primary breast lymphomas are B-cell lymphomas, with diffuse large B-cell lymphoma being the most prevalent.

Markers of Type 2 Inflammation and Immunosenescence Are Upregulated in Localized Scleroderma.

Localized scleroderma (LS) is an autoimmune, fibrotic skin disease that is thought to be triggered by environmental factors. Recent evidence from systemic autoimmune diseases proposed that the induction of immunosenescence may link environmental triggers with autoimmunity development. We aimed to explore the inflammatory signature in juvenile LS and investigate the presence of DNA instability and immunosenescence using publicly available transcriptomic data.

SETD2 loss-of-function uniquely sensitizes cells to epigenetic targeting of NSD1-directed H3K36 methylation.

Background: SETD2 is the sole epigenetic factor responsible for catalyzing histone 3, lysine 36, tri-methylation (H3K36me3) in mammals. Its role in regulating cellular processes such as RNA splicing, DNA repair, and spurious transcription initiation underlies its broader tumor suppressor function. SETD2 mutation promotes the epithelial-mesenchymal transition and is clinically associated with adverse outcomes highlighting a therapeutic need to develop targeted therapies against this dangerous mutation.
