Article Snippet: Funding information Key Research and Development Projects of Sichuan Science and Technology Department, Grant/Award Number: No. 2018SZ0266 Abstract Myocardial infarction (MI) remains a severe cardiac disease because of its high incidence and mortality worldwide.. A growing body of recent investigations have confirmed that LINC00961 acts as a tumor suppressor in diverse malignancies.. However, the biological significance of LINC00961 and its molecular mechanism in MI are still elusive.

Downregulation of Beclin-1 enhances apoptosis and reduces cell viability induced by bortezomib in NB4 cells. Cells were infected with lentiviruses expressing shRNAs (non-targeting control or Beclin-1). Puromycin-resistant cells were pooled after each infection. (A) Cells transfected with the control shRNA and shBeclin-1 were treated with or without bortezomib (20 nM) for 24 h, and the expression levels of cleaved caspase-3, cleaved PARP, Bcl-2, p62 and Beclin-1, and LC3-I to LC3-II conversion were determined by western blotting. (B) Ratio of Bcl-2 and β-actin expression levels. Data are presented as the mean ± standard deviation of three independent repeats. *P<0.05 and **P<0.01. (C) Ratio of LC3-II and β-actin expression levels. Data are presented as the mean ± standard deviation of three independent repeats. **P<0.01.
