Human/Mouse SOD1/Cu‑Zn SOD Antibody

Detection of SOD1/Cu-Zn SOD by Western Blot

The role of SOD1 and SOD3 antioxidant enzymes in the functions of AT-MSCs. (A) The protein expression of antioxidant enzymes in infant and elderly AT-MSCs. Infant AT-MSCs and elderly AT-MSCs were derived from 5 different donors, respectively (n = 5) and the comparison was conducted with infant AT-MSCs and elderly AT-MSCs at the same passage number.

Detection of SOD1/Cu-Zn SOD by Western Blot

The role of SOD1 and SOD3 antioxidant enzymes in the functions of AT-MSCs. (B) The protein expression of wild-type and SOD1 knockdown infant AT-MSCs. The knockdown experiments were conducted with infant AT-MSCs from 3 different donors (n = 3).

Detection of SOD1/Cu-Zn SOD by Western Blot

GFP-rMSCs following in vitro stress assays. (A) Trypsinized and re-plated GFP-rMSCs at 24 h following hydrogen peroxide treatment. PSF-treated cells were much more abundant and had begun dividing, but GFP-rMSCs not treated with PSF appeared to have lasting negative effects of H2O2 exposure. (B) Lactate dehydrogenase released into medium of the hydrogen peroxide-treated cells was a means to measure cell death. (C) Changes in expression of stress-related proteins Hif-1a, HSP70, and SOD1 in GFP-rMSCs following hydrogen peroxide treatment. * Indicates p < 0.5. Experiments were repeated twice. Bar =100 µm.

Detection of SOD1/Cu-Zn SOD by Western Blot

The co-overexpression of SOD1 and SOD3 significantly improved the poor functions of elderly AT-MSCs by the activation of the pERK/ERK pathway. (A) The protein expression of wild-type elderly AT-MSCs or with the co-overexpression of SOD1 and SOD3 (n = 3). (B) The ROS expression in wild-type elderly AT-MSCs or with the co-overexpression of SOD1 and SOD3 (n = 3). (C) The cellular senescence of wild-type elderly AT-MSCs or with the co-overexpression of SOD1 and SOD3 (n = 3). (D) Transplantation of wild-type elderly AT-MSCs or with the co-overexpression of SOD1 and SOD3 to an in vivo streptozotocin-induced diabetic ischemic flap mouse model (n = 3). (E) The protein expression of pERK/ERK in infant AT-MSC, wildtype elderly AT-MSCs, elderly AT-MSCs with the individual overexpression of SOD1 or SOD3 or elderly AT-MSCs with the co-overexpression of SOD1 and SOD3 (n = 3). (F) The protein expression of pERK/ERK under the presence of a MEK inhibitor (n = 3). (G) The mRNA expression of wound healing-related growth factors in elderly AT-MSCs with the co-overexpression of SOD1 and SOD3 under the presence of a MEK inhibitor (n = 3). (H) Transplantation of elderly AT-MSCs with the co-overexpression of SOD1 and SOD3 under the presence of a MEK inhibitor to an in vivo streptozotocin-induced diabetic ischemic flap mouse model (n = 3). In all above experiments, elderly AT-MSCs were derived from 3 different donors (n = 3). SOD1 + 3: elderly AT-MSCs with co-overexpression of SOD1 and SOD3. PD098059 (PD) was used as a MEK inhibitor. The data represent the mean ± SD. ***P < 0.001, **P < 0.01, *P < 0.05, ns no significance. The experiments were performed in triplicate.
