Abstract
Pathological consequences of circadian misalignment, such as shift work, show considerable individual differences, but the lack of mechanistic understanding hinders precision prevention to prevent and mitigate disease symptoms. Here, we employed an integrative approach involving physiological, transcriptional, and histological phenotypes to examine inter-individual differences in pre-symptomatic pathological progression, preceding irreversible disease onset, in wild-type mice exposed to chronic jet-lag (CJL). We observed that CJL markedly increased the prevalence of hepatic steatosis with pronounced inter-individual differences. Stratification of individual mice based on CJL-induced hepatic transcriptomic signature, validated by histopathological analysis, pinpoints dysregulation of lipid metabolism. Moreover, the period and power of intrinsic behavioral rhythms were found to significantly correlate with CJL-induced gene signatures. Together, our results suggest circadian rhythm robustness of the animals contributes to inter-individual variations in pathogenesis of circadian misalignment-induced diseases and raise the possibility that these physiological indicators may be available for predictive hallmarks of circadian rhythm disorders.

Abstract
Prolapsed uterine fibroids are pedunculated submucous fibroids that prolapse through the cervical canal. Herein, we describe the laparoscopic treatment of massive prolapsed submucous fibroids. A 47-year-old woman had experienced frequent urination and abnormal vaginal bleeding for 7 years. She presented with persistent lower abdominal pain. The uterine fundus was palpable at 3 cm above the umbilicus. Vaginal examination revealed a dark purple and easily bleeding mass in her vagina. Pelvic magnetic resonance imaging revealed a large mass prolapsing from the uterine endometrium, which occupied the cervical canal and vagina, without evidence of malignancy. Under a preoperative diagnosis of uterine fibroids with edematous degeneration, we performed laparoscopic uterine artery cutting, transvaginal removal of the fibroid by twisting, and total laparoscopic hysterectomy. Histopathological examination revealed leiomyoma with partial ischemia. Six days postoperatively, the patient was discharged without complications. This approach may be appropriate for the treatment of massive prolapsed submucous fibroids.

Abstract
Rearrangement of the BCL2 gene with the immunoglobulin (IG) genes is the most frequent genetic abnormality in B cell lymphoid neoplasms. In the majority of cases, breakages occur at two breakpoint cluster regions; major breakpoint cluster (MBR) and minor cluster region (mcr). In a minority of cases with non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL), rearrangements involving the 5' flanking region of the BCL2 (5'-BCL2) have been reported. Here, we investigated 196 patients with NHL and 31 with CLL, with regard to rearrangement of the BCL2 gene. Hybridization analyses using probes representing the three cluster regions revealed that a total of 57 patients had a rearrangement of the BCL2; 42 (73.7%) were within the MBR, seven (12.2%) were within the mcr, and nine (15.8%) had a rearrangement at the 5'-BCL2. The nine patients with 5'BCL2 rearrangement included two with follicular lymphoma, four with diffuse large cell lymphoma and immunoblastic variant, two with leukemic phase of follicular lymphoma, and one with CLL. Comigration analysis with probes for the IG heavy chain gene (IGH), kappa-chain gene (IG kappa) and lambda-chain gene (IG lambda), demonstrated a 5'-BCL2/IGH junction at the JH region in four patients with NHL derived from follicular center B cell. Thus, the 5'flanking region is a third cluster for recombination between the BCL2 and IGH, which is closely associated with the development of follicular center cell lymphoma. Molecular cloning of a 5'-BCL2/IGH junction demonstrated recombination of the two affected genes in divergent orientation. A 5'-BCL2/IG kappa junction was observed in two patients with immunoblastic lymphoma, and one with CLL had a 5'-BCL2/IG lambda recombination. Two patients, including one with a BCL2-MBR/JH junction, lacked obvious recombination of the 5'-BCL2 with IG genes, suggesting the presence of a deletion at the 5'-BCL2. Our findings demonstrated heterogeneity not only in clinicopathological presentation of B cell disease with rearrangement of 5'-BCL2, but also in molecular lesions resulting from the rearrangement.

Abstract
Previously, we reported the establishment of a human lymphoma cell line, FL-318, carrying a t(14;18)(q32;q21) chromosomal translocation. FL-318 cells had mu-heavy chain on the cell surface, while they expressed 'sterile' germ-line gamma transcripts, suggesting that the chromatin structure of the immunoglobulin heavy chain (IGH) locus was 'accessible' to class switch recombination. After several months of in vitro cell culture, we found a small population of FL-318 cells expressing the gamma-chain. Using a limiting dilution method, a mu-producing cell clone FL-318M, and gamma-producing FL-318G were isolated. Hybridization studies with various DNA probes from the IGH locus as well as the BCL2 gene demonstrated that the mu-constant gene was deleted on the functional IGH allele of FL-318G cells, and that the cells produced abundant productive gamma-chain messages. These studies indicated that FL-318 cells underwent spontaneous class switching during in vitro cell culture, unrelated to T cell interaction or antigenic stimulation.

Abstract
B-cell lymphomas, mainly follicular lymphomas, carrying a t(14;18) chromosomal translocation associated with rearrangement of the BCL2 gene and the immunoglobulin heavy chain (IGH) gene, share many similarities with germinal center B cells in the secondary lymphoid follicle. In the germinal center, antigen-stimulated B cells proliferate and differentiate while undergoing isotype class switching of their immunoglobulin heavy chains. To examine whether BCL2-positive lymphoma cells show class switch recombination similar to that in the germinal center B cells, we studied the genomic configurations of the IGH gene loci in 38 patients with B-cell lymphomas. Sixteen (80%) out of 20 patients with BCL2-positive lymphomas showed class switch recombination on translocated and/or productive IGH gene loci. Lymphoma cells from 7 of the 16 patients expressed the gamma-heavy chain on their surfaces, indicating functional class switching to the gamma-constant gene on the productive allele. By contrast, 6 (33%) of the 18 patients lacking the BCL2 rearrangements exhibited class switch recombination. Statistical analysis revealed that the BCL2-positive lymphomas underwent switch recombination on either allele at a significantly higher frequency than the BCL2-negative lymphomas (P = 0.0099). This indicates that follicular lymphoma, not only morphologically but also functionally, recapitulates the germinal center. We propose that the up-regulated BCL2 expression itself is capable of playing an important role in immunoglobulin class switching.

Abstract
The t(14;19)(q32;q13) is a recurring translocation found in some patients with chronic lymphocytic leukemia (CLL), and the t(14;19) juxtaposes the BCL3 gene on chromosome 19 with the immunoglobulin heavy chain gene (IGH) locus on chromosome 14. Genomic DNAs from 49 patients with chronic B-cell leukemia and the related lymphomas were examined by Southern blot hybridization using 2 separate probes, named p alpha 1.4P and p alpha .5B, from the BCL3 gene locus. None of the 18 patients with leukemic manifestations of non-Hodgkin's lymphomas had detectable BCL3 rearrangements. Of 31 patients with CLL, 2 had the BCL3 rearrangements. A comigration study using the C alpha and C epsilon constant gene probe from IGH indicated that the t(14;19) translocation occurred in these 2 patients, and they were diagnosed with CLL/prolymphocytic (PL) according to the French-American-British (FAB) classification. Probes for the IGH locus revealed that leukemia cells of the 2 patients each were clonal, indicating that both small lymphocytes and prolymphocytoid cells found in the peripheral blood of one patient had the t(14;19), as well as a major population of the small lymphocytes in the peripheral blood of a second patient. It thus appears that tumor cells carrying the t(14;19) constitute a distinct disease entity in a group of chronic B-cell leukemia, that has a converting potential to more aggressive forms.

Abstract
The t(14;19)(q32;q13) is a recurring translocation found in leukemic cells of some patients with chronic lymphocytic leukemia (CLL). The BCL3 gene was identified on chromosome 19 adjacent to the breakpoint of the translocation, and has been proposed to be a candidate proto-oncogene which may play a role in leukemogenesis. The current study of a Japanese patient with CLL revealed that the (14;19) is reciprocal at the molecular level; the BCL3 gene was juxtaposed to the 5' side of the S alpha 1 switch region of the immunoglobulin heavy chain gene (IGH) on the der(14) chromosome, and the IGH gene 5' to the S alpha 1 region was joined to chromosome 19 sequences on the der(19) reciprocal partner chromosome. The breakpoint on chromosome 19 was 16 kb upstream of the first exon of the BCL3 gene and 7 bp of chromosome 19 sequences were deleted at the point of the junction. The t(14;19) translocations so far molecularly analyzed consistently occurred within one of the two S alpha switch regions; however, sequence analysis of the chromosome 19 regions involved in the translocation failed to demonstrate an obvious sequence similarity with the switch region. The chromosomal breaks on chromosome 19 from two CLL patients having the t(14;19) were within Alu repeated sequences.
