Subjects with combined hyperlipidemia (CHL) were screened for mutations in the lipoprotein lipase (LPL) gene by single-strand conformational polymorphism, and a previously reported G-->A DNA sequence change in exon 2, causing substitution of Asp by Asn at position 9, was identified in 2 individuals.
Therefore, antibodies to CD79a and CD79b are useful in the differential diagnosis of B-cell neoplasms from T-cell neoplasms or myeloid neoplasms, or L and H lymphocyte predominance Hodgkin's lymphoma from classic Hodgkin's lymphoma.
The imbalance pattern of cHL subtypes suggests that different molecular pathways are activated, with REL or other genes on chromosomal band 2p15-p16 playing a fundamental role in the pathogenesis of classical Hodgkin lymphoma.
We have investigated whether common polymorphisms and mutations in the apolipoprotein (apo) E, lipoprotein lipase (LPL), and apo CIII genes influence atorvastatin or bezafibrate responses in patients with CHL.

In contrast, T-cell/histiocyte-rich large B-cell lymphoma can be distinguished from classical Hodgkin's lymphoma thanks to the presence of monoclonal IgH rearrangement and the CD 30-CD15-CD45+EMA+ immunophenotypic profile of the neoplastic cells in T-cell/histiocyte-rich large B-cell lymphoma.

These findings support the hypothesis of a germinal center B cell-derived origin of NLPHL, indicate a significant role of BCL6 in the pathogenesis of NLPHL, and provide further evidence of the genetic diversity underlying the pathogenesis of NLPHL and cHL.
Because several genes down-regulated in HRS cells are positively regulated by the transcriptional activator Pax-5, which is expressed in most HRS cells, we studied HL cell lines for mutations in the Pax-5 gene.However, no mutations were found.
Direct comparison of Epstein-Barr virus (EBV) latent membrane protein 1 (LMP-1) expression in Hodgkin's and Reed-Sternberg (HRS) cells on conventional full sections with the corresponding duplicate/triplicate tumour cores on the TMA showed a concordance of 100%, indicating that cHL-TMA is a reliable and representative method for evaluating gene expression profiles in situ.
Several of the differentially expressed genes may play a role in the pathogenesis of cHL because they represent potential oncogenes, such as rhoC, L-myc, and PTP4A, or transcription factors, such as ATF-5, ATBF1, and p21SNFT.

T-cell-directed chemokine thymus- and activation-regulated chemokine (TARC)- and/or macrophage-derived chemokine (MDC)-positive H&RS cells were detected in all 20 cases of HL MC and HL NS but only in 5 of 9 cases of HL-like ATLL.

Interferon-gamma-inducible protein-10 (IP10)- and monokine induced by interferon-gamma (MIG)-positive H&RS cells were detected in all 10 HL MC but only in 5 of 10 cases of HL NS and 2 of 9 cases of HL-like ATLL.
