We investigated the functional mechanism of long non-coding small nucleolar host gene 17 (SNHG17) in diffuse large B-cell lymphoma (DLBCL). lncRNAs related to the prognosis of patients with DLBCL were screened to analyze long non-coding small nucleolar host gene 17 (SNHG17) expression in DLBCL and normal tissues, and a nomogram established for predicting DLBCL prognosis. SNHG17 expression in B-cell lymphoma cells was detected using qPCR.

The in vitro THP release of the three conjugate micelles was conducted in pH 7.4 and 5.

GPC and NMR studies confirmed the co-polymer structure. The pendant 4-nitrophenyl carboxylate groups can react with amino-containing molecules, such as 3,6,9-trioxa-1,11-undecanediamine, doxorubicin and chitosan under mild conditions.

NMR, FT-IR, and GPC studies confirmed the copolymer structure. It could self-assemble into micelles in aqueous solution with critical micelle concentration (CMC) in the magnitude of mg/L, which changed with the composition of the copolymer.
