Highly efficient expression of human extracellular superoxide dismutase (rhEcSOD) with ultraviolet-B-induced damage-resistance activity in transgenic silkworm cocoons. INSECT SCIENCE 2023. [PMID: 38010045 DOI: 10.1111/1744-7917.13289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 09/20/2023] [Accepted: 09/24/2023] [Indexed: 11/29/2023]
Abstract
Extracellular superoxide dismutase (EcSOD) protects tissues from oxidative stress, and thus is considered as a therapeutic agent for many diseases such as atherosclerosis, hypertension, and cancer. However, cost-effective production of bioactive recombinant human EcSOD (rhEcSOD) remains a challenge. Herein, we developed an efficient strategy for producing active rhEcSOD by transgenic silkworms. rhEcSOD was successfully synthesized as homodimers and homotetramers in the middle silk gland and spun into the cocoons with a concentration of 9.48 ± 0.21 mg/g. Purification of rhEcSOD from the cocoons could be conveniently achieved with a purity of 99.50% and a yield of 3.5 ± 0.5 mg/g. Additionally, N-glycosylation at the only site of N89 in rhEcSOD with 10 types were identified. The purified rhEcSOD gained the potent enzymatic activity of 4 162 ± 293 U/mg after Cu/Zn ions incorporation. More importantly, rhEcSOD was capable of penetrating and accumulating in the nuclei of cells to maintain cell morphology and attenuate ultraviolet B-induced cell apoptosis by eliminating reactive oxygen species and inhibiting the C-Jun N-terminal kinase signaling pathway. These results demonstrated that the transgenic silkworm could successfully produce rhEcSOD with enzymatic and biological activities for biomedical applications.

Abstract
The carbon dioxide (CO2) lattice laser has been successfully used to treat facial skin photoaging induced by UV light. In this study, we analyzed the effect of CO2 lattice laser irradiation on skin photoaging, and investigated the underlying mechanisms. Our results demonstrate that the laser promoted collagen synthesis and proliferation of primary human skin fibroblasts, inhibited cell senescence, and induced expression of superoxide dismutase (SOD) and the signaling protein SMAD3. In addition, this laser reversed cell cycle arrest and fibroblast apoptosis induced by UVB irradiation, and restored fibroblast proliferation inhibited by SMAD3 silencing. Using a rat model of photoaging, our results show that the laser increased collagen expression and dermal thickness, demonstrating that the CO2 lattice laser has a profound therapeutic effect on photoaged skin. Together, our in vitro and in vivo data show that the CO2 lattice laser can reverse the skin aging caused by UVB, and indicate that this effect is mediated through SMAD3.

Abstract
We have observed that sperm quality parameters indicative of spermatozoa hyperactivation such are lower “linearity” and “straightness”, and as showed by this research “elongation”, were more pronounced in patients with normal spermiogram compared to the group of men with reduced sperm motility who were undergoing routine in vitro fertilisation. The research encompassed 97 men diagnosed with normozoospermia (n = 20), asthenozoospermia (n = 54) and oligoasthenozoospermia (n = 23). The findings indicate that sperm quality of patients with normal spermiogram diagnosed according to WHO criteria, may be compromised by showing premature spontaneous hyperactivation which can decrease the chances of natural conception. We assessed synergistic effects of multiple chemical elements in ejaculated semen to find if premature spontaneous hyperactivation of spermatozoa can be a sign of imbalanced semen composition especially of elements K, Ca, Cu and Zn. Human semen samples showing low or high baseline status of chemical elements concentrations were found in samples from all three diagnostic groups. However, correlation of K/Ca and Cu/Zn ratios, taking into account samples from all three groups of men, were negative at statistical significance level p = 0.01. We tested if the negative correlation between K/Ca and Cu/Zn ratio works for greater number of semen samples. We found the negative correlation to be valid for 175 semen samples at statistical significance of p = 0.00002. The ratio of K/Ca and Cu/Zn, i.e. increased concentrations of K and Zn in comparison to concentrations of Ca and Cu, were associated with a decrease of “straightness” in the group of men with normal spermiogram and pronounced spontaneous hyperactivation of spermatozoa, implying that these elements act in synergy and that the balance of elements and not their absolute concentrations plays the major role in premature spermatozoa hyperactivation in ejaculated semen.

Nrf2-dependent and Nrf2-independent induction of phase 2 detoxifying and antioxidant enzymes during keratinocyte differentiation. Arch Dermatol Res 2012; 304:387-95.

Abstract
As antioxidant enzymes can be actively modulated during keratinocyte (KC) differentiation, this study was aimed to evaluate the modulation of a group of phase 2 detoxifying and antioxidant enzymes (phase 2 enzymes) during KC differentiation. In postconfluence-induced differentiation model of KC, heme oxygenase-1 (HO-1), NADP(H):quinone oxidoreductase-1 (NQO-1), and glutathione S-transferase pi (GSTpi) were up-regulated at a transcriptional level. In Western blot analysis, the phase 2 enzymes were up-regulated by H(2)O(2), but down-regulated by N-acetyl cysteine, indicating the active role of reactive oxygen species for their expression during KC differentiation. When a redox-sensitive NF-E2 related factor-2 (Nrf2), a key transcriptional factor for phase 2 enzymes, was knocked down by small interfering RNA transfection in differentiated KCs, only NQO-1 was down-regulated in both mRNA and protein levels. In human skin, expression levels of the phase 2 enzymes were up-regulated in the differentiated KC in the normal epidermis and keratotic foci in squamous cell carcinoma, further supporting the differentiation-dependent expression of phase 2 enzymes in vivo. This study demonstrates that a group of phase 2 enzymes are modulated during KC differentiation via either Nrf2-dependent (NQO-1) or Nrf2-independent (HO-1 and GSTpi) ways.

Abstract
BACKGROUND NADP(H):quinone oxidoreductase-1 (NQO-1) is known for its protective role in skin carcinogenesis, but the expression of NQO-1 during keratinocyte (KC) differentiation has not been studied. OBJECTIVE The purpose of the current study was to evaluate modulation of NQO-1 and NF-E2-related factor-2 (Nrf2) during KC differentiation. METHODS Normal human epidermal keratinocytes (NHEKs) were induced to differentiation by prolonged culture after confluency (postconfluence). RESULTS NQO-1 was induced at the late stage of differentiation of NHEKs (7th day of postconfluence). The expression of postconfluence-induced NQO-1 was stimulated by 0.1 mM H(2)O(2), but attenuated by 5 mM N-acetylcysteine, implying that reactive oxygen species (ROS) are implicated in the expression of NQO-1 in differentiated KCs. Nrf2 was up-regulated at the earlier than NQO-1 induction (3rd day of postconfluence). The Nrf2-dependent expression of NQO-1 was further supported by Nrf2-siRNA experiments. A confocal study confirmed the differentiation-dependent induction and activation of NOQ-1 and Nrf-2 in NHEKs. Immunohistochemistry showed that NQO-1 was accentuated in the upper epidermal layers, supporting the notion that differentiation-dependent NQO-1 expression is functional in human skin in vivo. CONCLUSION These results demonstrate that NQO-1 is modulated during KC differentiation via Nrf2 pathway, suggesting the active role of NQO-1 in the differentiating epidermis.

Abstract
Ultraviolet (UV) B irradiation can severely damage the skin and even induce tumorigenesis. It exerts its effects by direct DNA modification and by formation of reactive oxygen species (ROS). We developed a strategy to genetically activate target gene expression of the transcription factor NF-E2-related factor 2 (Nrf2) in keratinocytes in vivo based on expression of a constitutively active Nrf2 mutant. Activation of Nrf2 target genes strongly reduced UVB cytotoxicity through enhancement of ROS detoxification. Remarkably, the protective effect was extended to neighboring cells. Using different combinations of genetically modified mice, we demonstrate that Nrf2 activates the production, recycling, and release of glutathione and cysteine by suprabasal keratinocytes, resulting in protection of basal cells in a paracrine, glutathione/cysteine-dependent manner. Most importantly, we found that endogenous Nrf2 controls selective protection of suprabasal keratinocytes from UVB-induced apoptosis through activation of cytoprotective genes. This finding explains the preferential UVB-induced apoptosis of basal cells, which is important for elimination of mutated stem cells as well as for preservation of skin integrity. Taken together, our results identify Nrf2 as a key regulator in the UV response of the skin.
