Gene Expression Analysis of Autophagy Markers in Primary and Secondary Myelofibrosis

<b>Background/Objectives</b>: According to previous research, the process of autophagy in myeloid neoplasms has proven to be ambivalent depending on the type and stage of the disease. The aim of our work was to investigate the mechanism of autophagy in patients with primary and secondary myelofibrosis. <b>Methods</b>: Based on the RT-PCR method, we retrospectively analyzed the expression of <i>Beclin-1</i> and <i>LC3B-II</i> in bone marrow cells of patients with primary and secondary myelofibrosis (74 participants) compared to the control group which had patients with lymphoma in a localized stage without bone marrow infiltration (11 participants). <b>Results</b>: There was no statistically significant difference in the expression of <i>Beclin-1</i> and <i>LC3B-II</i> between patients with primary and secondary myelofibrosis and control participants. Among patients with primary myelofibrosis, higher expression of <i>LC3B-II</i> was statistically significantly associated with lower DIPSS. Higher <i>Beclin-1</i> expression was statistically significantly associated with better patient survival. <b>Conclusions</b>: Our results suggest that the upregulation of autophagy genes may be associated with favorable prognosis and survival of patients with myelofibrosis.
