Bleomycin is complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It forms complexes with iron that reduce molecular oxygen to superoxide and hydroxyl radicals which cause single- and double-stranded breaks in DNA. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors. It is a medication used to treat cancer, including Hodgkin's lymphoma, non-Hodgkin's lymphoma, testicular cancer, ovarian cancer, and cervical cancer among others. It was initially developed by Bristol-Myers Squibb and has been listed.

Carcinogenicity 2B, possibly carcinogenic to humans.
Mechanism Of Toxicity In primary pulmonary endothelial cells, bleomycin initiates apoptosis via the extrinsic pathway. In relation to bleomycin-induced scleroderma, bleomycin exerts various effects on skin-constituted cells such as fibroblasts, keratinocytes, and endothelial cells, as well as immunocytes. Bleomycin upregulates gene expression of ECM proteins as well as fibrogenic cytokines such as TGF-β and CTGF in cultured human skin fibroblasts. Also, in vitro studies showed a dose-dependent stimulation of endothelial cell secretion of collagen synthesis by bleomycin, which was inhibited by the anti-TGF-β antibody.

Although patients with early-stage Hodgkin's lymphoma have a high rate of cure, a portion of these are resistant to or relapse after standard treatment. Current prognostic criteria based on clinical and laboratory parameters at diagnosis do not allow to accurately identify the subset of patients with less favourable clinical outcome. An increased number of tumour-infiltrating macrophages was found to be associated with shortened survival in patients with classic Hodgkin's Lymphoma. The aim of this study was to assess the clinical significance of the proportion of CD68-positive infiltrating macrophages in patients with early-stage classic Hodgkin's lymphoma. By using immunohistochemistry technique, we evaluated for CD68 expression diagnostic biopsies of 106 patients affected by supradiaphragmatic early-stage classic Hodgkin's lymphoma treated at our institution since 2000 to 2010. All patients were treated with adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy followed by radiotherapy in the majority.
4.Profibrotic role of WNT10A via TGF-β signaling in idiopathic pulmonary fibrosis.

BACKGROUND: WNT/β-catenin signaling plays an important role in the pathogenesis of idiopathic pulmonary fibrosis (IPF); however, the role of WNT10A via transforming growth factor (TGF)-β signaling remains unclear.
