BCL2 and AL amyloidosis: Moreover, the overexpression of miRs‐9‐5p and 181a‐5p demonstrated a substantial increase in the rate of apoptotic ALMC‐1 cells measured by flow cytometry after staining with Annexin V and propium iodide (PI) (Figure 3G,H), suggesting a biological effect of miR‐9‐5p and miR‐181a‐5p in regulating BCL2 family members in AL amyloidosis.
