The invention is directed to a method of prognosing in an individual a transformation from follicular lymphoma to diffuse large B-cell lymphoma (DLBCL) by measuring changes and / or lack of changes in certain groups of related clonotypes, referred to herein as “clans,” in successive clonotype profiles of the individual. A clan may arise from a single lymphocyte progenitor that gives rise to many related lymphocyte progeny, each possessing and / or expressing a slightly different immunoglobulin receptor due to somatic mutation(s), such as base substitutions, inversions, related rearrangements resulting in common V(D)J gene segment usage, or the like. A higher likelihood of transformation from follicular lymphoma to DLBCL is correlated with the persistence of clans in successive clonotype profiles whose clonotype membership fails to undergo diversification over time.

Compounds, pharmaceutical compositions including the compounds, and methods of preparation and use thereof are disclosed. The compounds are noscapine analogs. The compounds and compositions can be used to treat and / or prevent a wide variety of cancers, including drug resistant cancers. While the antitussive plant alkaloid, noscapine, binds tubulin, displays anticancer activity, and has a safe pharmacological profile in humans, structure-function analyses pointed to a proton at position 9 of the isoquinoline ring that can be modified without compromising tubulin binding activity. Noscapine analogs with various functional moieties at position 9 on the isoquinoline ring kill human cancer cells resistant to other anti-microtubule agents, such as vincas and taxanes. Representative analogs include the 9-nitro, 9-bromo-, 9-iodo-, and 9-fluoro-noscapines, which bind tubulin and induce apoptosis selectively in tumor cells (ovarian and T-cell lymphoma) resistant to paclitaxel, vinblastine and teniposide. Surprisingly, treatment with one of the analogs, 9-nitro-nos, at doses as high as 100 μM, did not affect the cell cycle profile of normal human fibroblasts. This selectivity for cancer cells represents a unique edge over the other available antimitotics. The compounds can perturb the progression of cell cycle by mitotic arrest, followed by apoptotic cell death associated with increased caspase-3 activation and appearance of TUNEL-positive cells. Thus, the compounds are novel therapeutic agents for a variety of cancers, including ovarian and T-cell lymphoma cancers, even those that have become drug-resistant to currently available chemotherapeutic drugs.

The constructing method for constructing a lymphoma animal model by using the NK cell lymphoma cell line, the T cell lymphoma cell line or the B cell lymphoma cell line, provided by the invention, has the advantages that a lymphoma cell can be fixed under the skin by using a fixing effect of matrigel so as to guarantee the tumor formation rate of the nude mouse; technical advantages of fast tumor formation and high tumor formation rate are shown; and on the other hand, in the passage process, the lymphoma animal model for passage can be resuscitated at any time and can be directly constructed under the coordination of freezing operation of relevant tumor tissue culture solution.

Marek's disease virus (MDV), the etiologic agent of Marek's disease, is a potent oncogenic herpesvirus. MDV is highly contagious and elicits a rapid onset of malignant T-cell lymphomas in chickens within weeks after infection. MDV codes for an oncoprotein, Meq, that shares resemblance with the Jun / Fos family of b-ZIP transcription factors. Earlier studies showed that Meq is responsible for development for T-cell lymphomas in chicken. In order to identify specific regions within the Meq gene, a series of recombinant MDV were generated in which a mutated gene was introduced in place of parental Meq gene. Various mutations were introduced at the phosphorylation sites, basic region, leucine zipper region and transactivation regions of the Meq gene. Several of these mutations have been shown to have an attenuated phenotype in chickens. In one embodiment, the present invention contemplates exploiting these mutations to develop MDV vaccines that are able to protect against challenge with highly virulent MDV strains.
