Article Title: Topical GDF11 accelerates skin wound healing in both type 1 and 2 diabetic mouse models.
Article Snippet: This study aimed to investigate the role of truncated growth differentiation factor 11 (GDF11), in which the recognition site of Furin from wild-type GDF11 was deleted to enhance the cellular stability, in skin wound healing in the setting of diabetes mellitus (DM) and the underlying mechanisms.. Our study found that both truncated and natural GDF11s effectively accelerated wound healing processes in both T1DM and T2DM mice with a potency compatible to PDGF, bFGF, and EGF, but being much higher than GDF8.. At the cellular level, GDF11 stimulated the proliferation and suppressed HG-induced apoptosis of HSFs.

Article Snippet: Abstract: Background : Growth differentiation factor 11 (GDF11) is a member of the transforming growth factor-β (TGF-β) super family.. It has multiple effects on development, physiology and diseases.. However, the role of GDF11 in the development of mesenchymal stem cells (MSCs) is not clear.

Article Title: Growth differentiation factor 11 accelerates liver senescence through the inhibition of autophagy
Article Snippet: The differentiated non‐transformed mouse hepatocyte cell line alpha mouse liver 12 (AML‐12) (American Type Culture Collection) were cultured in DMEM/F12 medium (11320082; Gibco) supplemented with 10% FBS (Gibco), 1× insulin‐transferrin‐selenium‐G supplement (41400045; Gibco), 40 ng/ml dexamethasone (D4902; Sigma‐Aldrich), 100 IU/ml penicillin, and 100 μg/ml streptomycin (Gibco), and maintained at 37oC in a humidified incubator containing 5% CO 2 gas. .. To determine whether GDF11 could affect hepatocyte senescence, primary hepatocyte isolated from old mice treated with GDF11 (100 ng/ml, 1958‐GD/CF; R&D Systems) for 48 h. To investigate whether the senescence effect of GDF11 was autophagy dependent, rapamycin (0.1 μM) was used to rescue the GDF11‐induced impairment of autophagic activity. .. In some experiments, mTORC1 activity was inhibited by depleting Raptor with specific small interfering RNA (siRNA) (Invitrogen), and TFEB activity was increased by overexpressing TFEB with Ad‐TFEB.

Article Title: GDF11 replenishment protects against hypoxia-mediated apoptosis in cardiomyocytes by regulating autophagy.
Article Snippet: GDF11 has been reported to play a critical role in rejuvenating hypertrophy heart, skeletal muscle, and blood vessel regeneration in aged mice.. Whether GDF11 can regulate autophagy in cardiomyocytes remains largely unknown.. Thus, the purpose of the present study was to investigate the effects of GDF11 on cardiomyocyte autophagy induced by hypoxia, in addition to the underlying mechanisms.

293T cells co-expressing PCSK5 M452I secrete mature ectopic GDF11 with intermediate efficiency. A, Catalytically active PCSK5 promotes ectopic GDF11 secretion. Cells were lipofected with 3 ng of the indicated PCSK5 allele (or EGFP overexpression control) plus 100 ng of GDF11, and conditioned medium was collected after 24 hours to measure GDF11 release by ELISA. PCSK5 T288P was included as a catalytically dead control ( 28 ). B, GDF11 release by PCSK5 M452I plus wildtype PCSK5 (PCSK5 WT ) is additive. Cells were treated as in ( A ) and compared with 1.5 ng PCSK5 WT plus 1.5 ng PCSK5 M452I . C, Cotransfection with oncogenic HRAS G12V approximates the level of prenylated HRAS (HRAS prenyl ) in MCF10DCIS.com. 293T cells were lipofected with 2 ng of HRAS G12V and 3 ng of the indicated PCSK5 allele (or EGFP overexpression control) and immunoblotted for HRAS with vinculin and p38 used as loading controls. MCF10A-5E cells are a negative control for HRAS overexpression. D, HRAS G12V cotransfection does not alter the relative GDF11 secretion efficiencies of wildtype PCSK5, PCSK5 M452I , and PCSK5 T288P . Cells were treated as in ( C ) and measured for GDF11 release by ELISA. For ( A ), ( B ), and ( D ), GDF11 ELISA results are normalized to the GDF11-only condition [gray dashed in ( A )] and shown as the mean ± SEM of N = 4 biological replicates. Differences among +GDF11 groups were analyzed by multiway ANOVA with PCSK5 genotype as a fixed effect. Significant factors were followed up pairwise by Tukey-Kramer post hoc analysis.

Inducible reconstitution of PCSK5 alleles in PCSK5 −/− MCF10DCIS.com cells. A, Approach to MCF10DCIS.com engineering. Cells were transduced with a destabilizing domain (DD)-containing Cas9-P2A-Venus ( 61 ) and a single-guide RNA targeting Exon 4 of PCSK5 (sgPCSK5). Transduced cells were treated with 200 nM Shield-1 ( 61 ) to stabilize Cas9-P2A-Venus and 2% matrigel to promote PCSK5 accessibility before sorting single Venus-positive cells into 10 ng/ml GDF11 (to aid recovery upon PCSK5 loss) and screening genomic DNA (gDNA) of expanded clones for knockout. One confirmed PCSK5 −/− clone was then transduced with sgPCSK5-resistant, tetracycline (tet)-regulated, V5-tagged alleles of PCSK5 and selected polyclonally for hygromycin resistance. B, Sequence-confirmed knockout alleles of MCF10DCIS.com clone 3D8. The PCSK5 coding sequence (CDS) is shown with annotations for the signal peptide (SP, purple), proprotein sequence (Pro, green), and peptidase domain (blue) including its catalytic triad (yellow stars). The protospacer adjacent motif (PAM) of sgPCSK5 is just upstream of the first triad amino acid, and deletions (white, Allele 1) or insertions (pink, Allele 2) induce frameshift mutations (gray) removing the first amino acid in the catalytic triad (black outlined stars) and producing premature stop codons (red). C, Quantification of reconstituted PCSK5 alleles by calibrating against recombinant V5-containing Multitag protein at the indicated copies per cell ( 63 , 72 ). Cells were treated with 1 μg/ml doxycycline for 24 hours, and total protein from counted cells was immunoblotted by two-color fluorescence detection for V5 (800 channel) with tubulin and p38 (700 channel) used as loading controls for cells. Copy number estimates are: PCSK5 WT , 136,000 ± 11,000 copies per cell; PCSK5 M452I , 164,000 ± 6,000 copies per cell; PCSK5 T288P , 176,000 ± 15,000 copies per cell ( N = 4 biological replicates).
