Our findings showed BMI, and BMI in early adulthood (aged 18-21 years) is associated with the risk of Hodgkin's and non-Hodgkin's lymphoma (HL and NHL), diffuse large beta-cell lymphoma (DLBCL), Leukaemia including acute and chronic myeloid lymphoma (AML and CML), and chronic lymphocytic leukaemia (CLL) and multiple myeloma (MM).
In the further stratified and sensitivity analyses, significantly increased breast cancer risk was found in Asians and Indians, significantly decreased colon cancer risk was found, significantly decreased colorectal cancer risk was found in male population, significantly increased gastric cancer risk was found in Caucasians and Asians, significantly increased hepatocellular cancer risk was found in Asians, significantly decreased adult acute lymphoblastic leukemia (AALL) risk was found in Caucasians, significantly decreased childhood acute lymphoblastic leukemia (CALL) risk was found in Asians, and significantly increased multiple myeloma and NHL risk was found in Caucasians.
In a survey of human B-NHL AID was found to be constitutively expressed in follicular lymphoma and in diffuse large B-cell lymphoma but to be absent in B-precursor lymphoblastic leukemia, in mantle cell lymphoma, and in plasma cell myeloma.
Using specific ELISAs, PEL cell lines were found to produce large amounts of interleukin-6 (IL-6; 10-5000 pg/ml), IL-6 soluble receptor (IL-6sR; 30-600 pg/ml), IL-10 (600-80,000 pg/ml) and oncostatin M (OSM; 50-80 pg/ml) which in most cases were significantly higher than the levels produced by the Burkitt, B-NHL or myeloma cell lines; on the contrary, PEL cell lines did not elaborate significant levels of macrophage inhibitory protein (MIP-1alpha) and leukemia inhibitory factor (LIF).
A chromosomal translocation (Tx) that interrupts the transcription of either c-Myc or Pvt 1 is the principal lesion in many B cell malignancies including Burkitt's Lymphoma (BL), AIDs-NHL, mouse plasmacytoma (Pct) and possibly multiple myeloma (MM).
