Cell cycle deregulation in B-cell lymphomas.
Disruption of the physiologic balance between cell proliferation and death is a universal feature of all cancers. In general terms, human B-cell lymphomas can be subdivided into 2 main groups, low- and high-growth fraction lymphomas, according to the mechanisms through which this imbalance is achieved. Most types of low-growth fraction lymphomas are initiated by molecular events resulting in th...
متن کاملCell kinetics and cell cycle regulation in lymphomas.
The proliferative indices of non-Hodgkin's lymphomas are useful prognostic indicators and provide information independent of other histological and clinical variables. However, proliferative indices alone do not suffice to characterise cell growth. A high cell production rate may be compensated, almost or fully, by a high cell deletion rate. A re-evaluation of parameters of cell kinetics in vie...
متن کاملCell cycle markers for live cell analyses.
Many cellular processes are regulated by cell cycle dependent changes in protein dynamics and localization. Studying these changes in vivo requires methods to distinguish the different cell cycle stages. Here we demonstrate the use of DNA Ligase I fused to DsRed1 as an in situ marker to identify S phase and the subsequent transition to G2 in live cells. Using this marker, we observed changes in...
متن کاملSimultaneous analysis of DNA and cell surface immunoglobulin in human B-cell lymphomas by flow cytometry.
Cell suspensions prepared from human B-cell lymphomas were analyzed for cellular DNA and cell surface immunoglobulin (SIg) by flow cytometry. In addition to SIg-bearing neoplastic B-lymphocytes, these tumors contain nonneoplastic cells. Flow cytometry permitted selective analysis of DNA in subpopulations defined by the membrane antigen SIg and also permitted analysis of SIg of subpopulations de...
متن کاملCell cycle and apoptosis: A review
Cancer is characterized by abnormally excessive cell proliferation. Cell proliferation, the process by which a cell grows and divides to produce two daughter cells. Each of these daughter cells divides to produce two new cells, steps that are called cell cycle. Meanwhile, apoptosis is a highly regulated process of cell death, which is involved not only in the development of shape and morphogene...
