STEROID CATARACT MECHANISM

GCs downregulated the expression of CXCR4 under both normoxic and hypoxic conditions, thereby reducing the migration and wound healing ability of EPCs. GCs are known to exert anti-proliferative activities against various cells, including neural cells, osteoblasts, osteosarcoma cells, hepatoma cells, and lung, ovarian, and prostate cancer cells 39 — In addition, although in our present study, GC treatment showed no apoptosis induction in EPCs after h treatment, a further time-course study is necessary to examine the effects of GC to induce EPCs apoptosis at later time points.

CCL2 is the proinflammatory chemokine which is responsible for the inflammatory cell recruitment It is reported that CCL2 promotes wound healing in diabetic mice by inducing macrophage In injured tissues, the surrounding cells secrete SDF-1, which recruits the CXCR4-expressing cells to the wound sites and play their functions in wound healing A study in coronary artery disease patients showed that the dysregulation of CXCR4 signaling reduced the migratory capacity of EPCs in these patients compared to healthy subjects In our study, we found that, under GC treatment, the downregulation of CXCR4, together with the contribution of impaired proliferation, led to a reduced in vitro wound healing ability of EPCs in the migration scratch assay.

These impaired effects might be involved in the low homing ability of EPCs to the injured tissues in the mouse flap model. PGE2 has been proven to induce the expression of CXCR4 in several cells, such as myeloid-derived suppressor cells and microvascular endothelial cells 31 , In addition, the inhibitory effects of GCs on prostaglandin synthesis have been well-demonstrated in various cell types and tissues by the mediation of multiple pathways 51 , PGE2 is a potent upstream mediator of several genes through interaction with its receptors EPs , including EP1, EP2, EP3, and EP4, thereby recruiting the transcription factors and modulating the target gene expression In addition, previous reports showed that only EP4 regulates the migration of numerous cells 55 — For instance, EP4 regulates the migration of dendritic cells in mice via selective action on PI3K In addition EP4 is also involved in breast cancer cell migration during tumor invasion 56 and enhances the migration of rat smooth muscle cells Hypoxia plays a crucial role in modulating the functions of many types of cells via the activation of HIF Hypoxic preconditioning promoted the survival, differentiation, and function of EPCs for the preservation of the left ventricle in acute myocardial ischemia mice We therefore expected that hypoxic treatment might reverse the negative effects of GCs on the impaired expression of CXCR4.

In addition, our data indicated the different mechanisms underlying the regulation of CXCR4 under normoxic and hypoxic conditions. MSCs are considered to contribute to the vascular niche development by providing growth factors A previous report found that the level of SDF-1 protein in the serum of GC-treated patients was significantly decreased compared with untreated patients Because the biologic effects of chemokines are mediated by their corresponding receptors, the interplay between SDF-1 and CXCR4 may provide another way to regulate the distribution of circulating EPCs These two discoveries thoroughly show why GC-treated patients have a reduced number of circulating EPCs and a consequently impaired angiogenic ability that leads to dreadful outcomes, like avascular necrotic femoral head ANFH.

Synthetic GCs have been developed to help treat many different conditions, such as autoimmune disorders, allergies and asthma, cancer, and surgery Despite the multi-functions, GCs causes various side effects including chronic wound It is reported that patients who receive GC treatment for 30 days prior to wounding or operation have a 2-fold increase in wound infection, three times increase in wound dehiscence, and four times increased mortality compared to those who not get the GC treatment In addition, rheumatoid arthritis patients who receive long term GC treatment and surgery have the high risk of delayed wound healing Therefore, it can be implied that the patients with GC-induced chronic wound have become the target of EPC therapy which helps to accelerate wound healing.

Previous studies showed that glucocorticoid treatment impairs the corneal neovascularization in mice and rabbit which implied the possibility of abnormal vascularization process, including the dysfunction of EPCs and ECs 68 , In addition, EPCs from mice with aldosterone treatment showed the impaired differentiation ability to ECs and migration ability. In summary, our study demonstrated that GCs suppress the migration ability and wound healing function of EPCs by the downregulation of CXCR4 under both normoxic and hypoxic conditions.

Further studies should be performed to carefully assess wound healing functions of EPCs derived from patients who have been receiving long-term treatment with GCs.

Impaired CXCR4 signaling contributes to the reduced neovascularization capacity of endothelial progenitor cells from patients with coronary artery disease. Circ Res. Wound healing was impaired by a single subcutaneous injection of 6 mg of methylprednisolone acetate at the time of surgery.

This time point was chosen since the inhibitory effect of glucocorticosteroids on wound healing is most pronounced when administration of the hormone begins just prior to the onset of inflammation in the healing process. The following preparations of retinoids were used: 1 all- trans -retinoic acid mg of all-trans-retinoic acid per kilogram of diet ; 20 g of diet fed daily approximately 2. The animals were assigned to 4 treatment arms: 1 corticosteroids alone, 2 either of the 2 retinoids alone, 3 corticosteroids and either of the 2 retinoids, and 4 control animals.

All animals drank water ad libitum. Wound fluid was harvested by sterile aspiration with a syringe at different times in the various experiments. Each sample was assayed in 2 or 3 replicate assays and the results averaged. Insulin-like growth factor-I levels were measured at day 17 by radioimmunoassay. Insulin-like growth factor-I was separated from its binding proteins prior to radioimmunoassay by the formic acid—acetone extraction method.

The animals were killed on day 17 and the cylinders were explanted. All accessible wound tissue was removed mechanically from the implants. Hydroxyproline content of the tissue within the wound cylinders was assessed by high-performance liquid chromatography with a modified method after Lindblad and Diegelmann.

Immunohistochemistry was performed on full-thickness skin sections obtained from the back of the animals from an unwounded area. Oral all- trans -retinoic acid significantly reversed the steroid-induced IGF-I decrease toward control levels Figure 3 A. Oral all- trans -retinoic acid alone significantly increased hydroxyproline content beyond normal levels when compared with animals fed the control diet at day 17 Figure 4 A.

Corticosteroid hormones are widely used clinically to treat a variety of diseases by suppressing inflammation and immune functions. Soon after the discovery of the therapeutic potential of corticosteroids, their adverse effects on wound healing became evident. The depressive effect of steroids on wound healing has long been presumed to depend on the postponement of the inflammatory reaction, without which the healing sequence cannot proceed. Ehrlich et al 2 serendipitously noted that glucocorticoid-mediated reductions in inflammatory cell infiltration, fibroplasia, and deposition of collagen fibers are prevented by concurrent vitamin A therapy.

The proposed mechanism is an antagonistic effect of corticosteroids and vitamin A on multiple inflammatory components. However, no other mechanistic detail has been added since then. Glucocorticosteroids decrease collagen synthesis also in unwounded connective tissues and fibroblast cell culture. The decrease of type I collagen synthesis caused by steroids has been attributed to a decrease of the steady-state level of total cellular type I procollagen messenger RNAs.

Retinoids regulate the expression of secreted growth factors. At least for certain cells this can be correlated with the ability of retinoids to increase the expression of transglutaminase, one of the components in the activation mechanism. The goal of this study was to identify whether the above data could be used to explain the effects of corticosteroids and retinoids during wound healing.

All- trans -retinoic acid significantly increased hydroxyproline levels beyond control levels, an effect that could not be shown with the 9- cis -isomer. This information might be valuable for further studies and could be significant for therapy of healing deficits.

It is tempting to speculate that all- trans -retinoic acid might actually enhance normal healing. Differences in the pharmacokinetic properties of orally administered all- trans -retinoic acid and 9- cis -retinoic acid have been described. Potentially, broader receptor activation may contribute to the greater activity of the 9- cis -isomer. Additionally, 9- cis -retinoic acid does not induce its own oxidative inactivation to the same extent as all- trans -retinoic acid.

Further studies on the comparative pharmacokinetics of 9- cis -retinoic acid and all- trans -retinoic acid as well as their activation of target genes might be useful for enhancing the control that surgeons have over wound healing. We attempted but could not repeat prior data showing that parenteral vitamin A palmitate has the same effects as seen for orally fed all- trans - and 9- cis -retinoic acid. In higher concentrations parenteral vitamin A led to toxic effects including weight loss.

According to the manufacturer, the parenteral retinoid preparations used in earlier experiments, which are now unavailable, were different mixtures of the various retinoid metabolites and isomers. The palmitate ester is metabolized differently than other forms, and this difference rather than the route of administration, in our opinion, best explains the failure of the parenteral preparation to share the vulnerary results of the orally given forms.

The immunohistochemical studies were performed for 2 reasons. First, it was necessary to demonstrate that the animals had developed significant systemic effects of the steroids despite the short treatment duration. Second, we wished to test a long-held hypothesis that systemic retinoids given in treatment of steroid-suppressed repair might diminish the therapeutic potential for which the steroids are being given.

Clearly, the animals were significantly affected, and there is potential for diminishing the desired effects of steroid therapy. These observations raise several caveats. First, treatment of wound failure in this circumstance should be cautious when interruption of steroid effect might become problematic. Local retinoid therapy to wounds is also clinically effective. Second, systemic use should be short-term recognizing that excess vitamin A is stored in the liver.

It is unknown whether systemic retinoids might be used to forestall wound failure when interruption of the steroid effect is not critical as for patients with low-grade rheumatoid arthritis who are being prepared for operations.

However, these data also raise the idea that retinoids might be used to ameliorate signs and symptoms of Cushing's disease or even hasten recovery from Cushing's syndrome after the need for steroid therapy is ended. These effects might well be shared by other growth factors and substances that are relevant for the healing process. Wicke med. Our website uses cookies to enhance your experience.

Wound healing was impaired by a single subcutaneous injection of 6 mg of methylprednisolone acetate Depo-Medrol. Two preparations of retinoids were used in separate experiments: all- trans -retinoic acid and 9- cis -retinoic acid that were fed orally. Conclusions Steroids and retinoids have antagonistic effects on growth factors and collagen deposition in wound healing. These effects can be relevant for treatment options in a clinical setting.

When administered sufficiently early after injury, high corticosteroid levels delay the appearance of inflammatory cells, fibroblasts, the deposition of ground substance, collagen, regenerating capillaries, contraction, and epithelial migration. Retinoids have the unique ability to reverse these inhibitory effects, except for wound contraction.

Retinoids are global regulators of the growth and differentiation of many cell types. It is now appreciated that all actions of retinoids are mediated through 2 families of nuclear receptors belonging to the steroid hormone receptor superfamily.

The ligand for these receptors is retinoic acid. Other, more reduced metabolites function to control the storage, trafficking, and conversion to the metabolically unstable active form, retinoic acid. Its effects on the extracellular matrix are more complex and more profound than that of any other growth factor. Insulin-like growth factor I is a major regulator of growth and development and of wound healing.

Four wire mesh wound cylinders were implanted under the dorsal skin of 72 male Sprague-Dawley rats weighing g. Wire mesh cylinders were chosen to obtain wound fluid and wound tissue simultaneously and to assess wound fluid at different times. Wound healing was impaired by a single subcutaneous injection of 6 mg of methylprednisolone acetate at the time of surgery.
