Background: Segmental chromosome aberrations, defined as presence of aberrations, deletion, or imbalance in the chromosomal arms, have long been considered as a predictor of poor prognosis of patients with neuroblastoma. The objective of this meta-analysis is to quantitively analyze the hazard ratios (HRs) of different whole or segmental chromosome aberrations for overall survival (OS) rate or event-free survival (EFS) rate of patients with neuroblastoma.
Methods: Relevant studies about chromosome, neuroblastoma, predictor, prognosis, and survival published from the inception to April 2023 in the databases of PubMed, Embase, and Web of Science were searched, screened, and reviewed.

Background: Bone development involves the rapid proliferation and differentiation of osteogenic lineage cells, which makes accurate chromosomal segregation crucial for ensuring cell proliferation and maintaining chromosomal stability. However, the mechanism underlying the maintenance of chromosome stability during the rapid proliferation and differentiation of Prx1-expressing limb bud mesenchymal cells into osteoblastic precursor cells remains unexplored.
Methods: A transgenic mouse model of RanGAP1 knockout of limb and head mesenchymal progenitor cells was constructed to explore the impact of RanGAP1 deletion on bone development by histomorphology and immunostaining.

Plasma cell leukemia (PCL) is a rare aggressive variant of multiple myeloma. PCL is diagnosed when clonal plasma cells constitute more than 20 % of the total circulating leukocytes or when the absolute plasma cell count exceeds 2 × 10 /L. Extramedullary involvement including cavity effusion is frequently seen at the time of diagnosis.
