Objectives: This case-control study was designed to evaluate the association of three COL2A1 single nucleotide polymorphism (SNPs) (rs1793953, rs2276454, and rs1793937) and Aggrecan variable number of tandem repeat (VNTR) polymorphisms with the risk and clinicopathological features of intervertebral disc degeneration (IVDD) in a Chinese Han population.
Materials And Methods: Data from 295 IVDD patients (case group) and 324 healthy volunteers (control group) were collected between January 2012 and December 2014. Magnetic resonance examinations were conducted on all included subjects.
Pleiotrophin (PTN) has been demonstrated to be strongly expressed in many fetal tissues, but seldom in healthy adult tissues. While PTN has been reported to be expressed in many types of tumors as well as at high serum concentrations in patients with many types of cancer, to date, there has been no report that PTN is expressed in leukemia, especially in lymphocytic leukemia. We isolated the CD19(+) subset of B cells from peripheral blood from healthy adults, B-cell acute lymphocytic leukemia (B-ALL) patients, and B-cell chronic lymphocytic leukemia (B-CLL) patients and examined these cells for PTN mRNA and protein expression.
