Retraction: The lnc-SNHG1 Gene Is Overexpressed and Correlates with Increased White Blood Cell Count, Poor Induction Treatment Response, and Poor Survival Profile in Adult Acute Myeloid Leukemia

Objective: Long noncoding RNA small nucleolar RNA host gene 1 (lnc-SNHG1) is involved in leukemogenesis via mediating multiple pathways. The current study aimed to further explore its clinical roles in disease risk, clinical features, and prognosis in patients with acute myeloid leukemia (AML). Materials and Methods: A total of 161 adult AML patients, 50 patients as a disease control (DC) group, and 50 healthy individuals as a healthy control (HC) group were enrolled and bone marrow mononuclear cells were collected. Subsequently, reverse transcriptionquantitative polymerase chain reaction (RT-qPCR) was performed to measure lnc-SNHG1 expression. Results: Lnc-SNHG1 expression was higher in AML patients than in the DC and HC groups (both p<0.001), with good value in distinguishing AML patients from DC and HC individuals (area under the curve of 0.726 and 0.884, respectively). Moreover, lnc-SNHG1 expression was positively associated with white blood cell (WBC) count (p=0.008) but was not correlated with other clinical features such as cytogenetics, molecular genetics, and risk stratification (all p>0.05). Lnc-SNHG1 expression was also associated with a lower complete remission (CR) rate (p=0.001). Patients with lnc-SNHG1 expression in the fourth quantile had the worst CR rates compared to patients with lnc-SNHG1 expressions in the first, second, and third quantiles (all p<0.05). Furthermore, lnc-SNHG1 expression was correlated with unsatisfactory event-free survival (p<0.001) and overall survival (p=0.002), which were worst in patients with lnc-SNHG1 expression in the fourth quantile compared to patients with lnc-SNHG1 expressions in the first, second, and third quantiles (all p<0.05). Conclusion: Lnc-SNHG1 overexpression is associated with elevated WBC count, poor induction treatment response, and poor survival profile in cases of AML and it may serve as a potential indicator for AML.
