Insights
Hodgkin's disease (HD) shows more profound cell cycle disruptions, specifically in the G2/M transition, compared to anaplastic large cell lymphomas (ALCL). This involves issues with mitosis completion and cell loss in HD.
Area of Science:
- Cellular and Molecular Biology
- Oncology
- Hematopathology
Background:
- Hodgkin's disease (HD) and anaplastic large cell lymphomas (ALCL) share CD30 positivity.
- Both are lymphomas with distinct cellular kinetic profiles.
Purpose of the Study:
- Compare cellular kinetic parameters in HD versus ALCL-C and ALCL-HL.
- Focus on the G2/M cell cycle transition and maturation/mitosis promoting factor (MPF) regulation.
Main Methods:
- Quantified cells expressing p34cdc2 (p34) and cyclin B-1 (cyclin-B).
- Assessed multinucleation, large atypical cells (LAC), and ana/telophase indices (ATI).
- Correlated these parameters between HD, ALCL-C, and ALCL-HL.
Main Results:
- HD exhibited prominent abortive mitosis, multinucleation, and CD30+ cell deletion, unlike ALCL-C.
- HD showed lower cyclin-B expression in LAC compared to ALCL-C.
- ALCL-HL occupied an intermediate position between HD and ALCL-C.
Conclusions:
- Cell cycle regulation, particularly MPF kinetics, is more severely impaired in HD than in ALCL-C.
- These findings highlight distinct cellular kinetic differences between these lymphoma subtypes.
Abstract:
Our study was designed to compare cellular kinetic parameters of classical Hodgkin's disease (HD) with those of anaplastic large cell lymphomas (ALCL-C, common type; and ALCL-HL, Hodgkin's like), with a particular focus on the G2/M transition. These disorders share some phenotypic properties, e.g., CD30 positivity of putative neoplastic cells. The percentages of cells expressing p34cdc2 (p34) and cyclin B-1 (cyclin-B), which form a complex (maturation/mitosis promoting factor, MPF) regulating the G2-M phases of the cell cycle, were also registered. Highly significant differences between HD and ALCL-C were recognized: a) in HD, evidence for abortive mitosis (i.e., difficulty to proceed beyond the metaphase stage) and consequent multinucleation and/or deletion of CD30+ cells was prominent, in contrast to ALCL-C. This was associated with a markedly lower fraction of large atypical cells (LAC) expressing cyclin-B in the cytoplasm and the nucleus (C + N) in HD than in ALCL-C; b) the extent of multinucleation of CD30+ cells in HD, but not in ALCL-C, was correlated with the %p34+ LAC; c) the proportions of LAC expressing p34 and/or cyclin-B (C) were positively related to the percentages of cyclin-B (C + N)+ LAC in ALCL-C but not in HD; d) in HD, in contrast to ALCL-C, the size of the fraction of cyclin-B (C + N)+ LAC did not correlate with the ana/telophase indices (ATI, reflecting successful completion of mitosis) and the magnitude of cell loss; e) in ALCL-C, the percentages of p34+ LAC were positively correlated with ATI or the degree of CD30+ cell deletion, but inversely in HD. With regard to all parameters mentioned above, ALCL-HL tended to take an intermediate position between HD and ALCL-C, but sided more with the latter. In conclusion, our present results suggest a derangement of MPF kinetics and functions that is more profound in HD than in ALCL-C.
