Erratum
In the original article by Syeda, et al., entitled „Inhibition of Prenylation Promotes Caspase 3
Activation, Lamin B Degradation and Loss in Metabolic Cell Viability in Pancreatic B-Cells“ [Cell
Physiol Biochem 2017;43(3):1052-1063, DOI: 10.1159/000481702], there has been a mistake in
the Fig. 4 (the panels A-D from Fig. 3 are repeated in Fig. 4). The correct Fig. 4 is displayed below.
The authors confirm that all of the results and conclusions of the article remain unchanged, as
well as the figure legend.
The authors sincerely apologize for this mistake.
Fig. 3. FTI-277 induces
caspase-3 activation, lamin
degradation and loss in cell
viability in INS-1 832 cells.
Panel A: INS-1 832/13 cells
were incubated in a medium
containing low glucose (2.5
mM; LG) in the absence and
presence of FTI-277 (10 µM)
for 24 hrs. Caspase 3 activation
and lamin B degradation for
each condition was determined
by Western blotting (Panel
A). Equal protein loading
was ensured by re-probing
the membrane with anti
β-actin. Intensity of protein
bands was quantified by
densitometry. Data represent
mean ± SEM from three
independent experiments, and
are expressed as fold change
in caspase 3 activation (Panel
B) and lamin B degradation
(Panel C). *P<0.05 vs. LG. Panel
D: Lysates from INS-1 832/13
cells treated with low glucose
(2.5 mM) in the absence and
presence of FTI-277 (10 µM)
were subjected to a single-step
centrifugation to separate the
supernatant cytosolic (Cyto)
and the membrane-pellet (Mem) fractions followed by hydrophobic (HPB) and hydrophilic (HPL) phase
partitioning with Triton X-114 detergent [23,24]. The lysate proteins were resolved by SDS-PAGE and
transferred to a nitrocellulose membrane. The membrane was probed for cleaved caspase 3 and lamin B.
A representative blot from two independent experiments is shown here. Panel E: INS-1 832/13 cells were
treated with media containing low glucose (2.5 mM; LG) alone and in the presence of diluent (DMSO), FTI-
277 (10 µM) for 24 hrs. Changes in cell morphology were visualized by light microscopy. Panel F: INS-1
832/13 cells were treated with low glucose (2.5 mM; LG) in the absence and presence of FTI-277 (10 µM).
After 24 hrs. cell viability was assessed by the MTT assay. Data represent mean ± SEM and are expressed as
percent cell viability. *P<0.05 vs. LG.
