Abstract:
Objective To investigate the relationship between the expression levels of long non-coding RNA(lncRNA)metastasis-associated lung adenocarcinoma transcript 1(MALAT1)and leptin levels in the patients with multiple myeloma,as well as the role in the diagnosis and prognosis of multiple myeloma.Meth-ods A total of 60 patients with newly diagnosed multiple myeloma in this hospital from January 2018 to Oc-tober 2020 were selected as the patient group.Additionally,60 healthy individuals during the same period were recruited as the control group.The levels of serum lncRNA MALAT1 and leptin in the test population were detected.The correlation between the two and thier ratio as well as their role in disease prognosis were invest-gated.Results The expression levels of serum lncRNA MALAT1 and leptin in the patients group were signif-icantly higher than those in the control group,and the difference was statistically significant(P＜0.05).A-mong the various stages of Durie-Salmon(DS)staging,the expression levels of lncRNA MALAT1 and leptin from stage I,stage Ⅱ and stage Ⅲ were in turn from high to low,and the differences were statistically signifi-cant(P＜0.05).Among different immune types,the expression level of lncRNA MALAT1 in the patients with light chain type was highest,which in those with non-secretory type was lowest.The leptin levels in the patients with light chain type,IgG type,IgA type and non-secretory type were in turn from high to low,and the differences were statistically significant(P＜0.05).Furthermore,the expression level of lncRNA MAL-AT1 was positively correlated with leptin(r=0.41,P＜0.05).There were statistically significant differences in the expression levels of lncRNA MALAT1,leptin levels,and lncRNA MALAT1/leptin ratio between before and after treatment in the patients with treatment effect(P＜0.05).However,there was no statistically sig-nificant difference in these two indices between before and after treatment in the patients with no treatment effect(P＞0.05).After treatment,the median survival time for the patients with serum lncRNA MALAT1/leptin ratio＜3 was 27 months(95％CI:21.949-27.120),while which for the patients with serum lncRNA MALAT1/leptin ratio 3 was 14 months(95％CI:12.076-22.199),and the difference was statistically sig-nificant(P=0.014).Conclusion lncRNA MALAT1 and leptin exhibit a certain extent of synergistic effect in the de-velopment and progression of multiple myeloma.The ratio of these two could be used to evaluate the prognosis of the patients.
