Article Title: The role of leptin in regulation of the soluble amyloid precursor protein α (sAPPα) levels in lung cancer cell media

doi: 10.1038/s41598-024-55717-y

Figure Lengend Snippet: Treatment of A549 cells with leptin increased ACh levels and inhibited the activities of p53 and AChE while opposite effects were found upon transfection with siRNA targeting either leptin or Lep-R. Cells (0.2 × 10 5 ) were grown in 10% FBS-supplemented media for 24 h. The following day, the cell monolayers were incubated in serum-free media for 24 h, then the media was replaced with fresh serum-free media. The cells were then either untreated or treated as indicated with leptin (50 ng/mL) or the indicated siRNAs and allowed to incubate for 72 h. The activity of p53 ( A ) in cell lysates, the levels of ACh in the cell media ( B ), the levels of AChE ( C ) and activity ( D ) in the media were measured as described in the “ ” section. The same amount of protein (3 µL of 600 µg/mL total protein) was used for all assays. The graphs summarize the results expressed as means ± SD (n = 5) using the GraphPad 10.0.2 software. Fold change was calculated relative to the control of each cell line ( B ) or to the A549 control ( A , C , D ). Asterisks indicate a statistically significant difference from the corresponding control, Mann–Whitney test. Statistical differences between different groups were analyzed by an ordinary one-way analysis of variance (ANOVA) followed by Tukey’s post-hoc multiple comparison test, **p < 0.01. Absence of asterisks indicates no significance.
