Abstract
Objective: Anoikis is a kind of programmed cell death that is triggered when cells lose contact with each other or with the matrix. However, the potential value of anoikis-related genes (ARGs) in keloid (KD) has not been investigated. Approach: We downloaded three keloid fibroblast (KF) RNA sequencing (RNA-seq) datasets from the Gene Expression Omnibus (GEO) and obtained 338 ARGs from a search of the GeneCards database and PubMed articles. Weighted correlation network analysis was used to construct the coexpression network and obtain the KF-related ARGs. The LASSO-Cox method was used to screen the hub ARGs and construct the best prediction model. Then, GEO single-cell sequencing datasets were used to verify the expression of hub genes. We used whole RNA-seq for gene-level validation and the correlation between KD immune infiltration and anoikis. Results: Our study comprehensively analyzed the role of ARGs in KD for the first time. The least absolute shrinkage and selection operator (LASSO) regression analysis identified six hub ARGs (HIF1A, SEMA7A, SESN1, CASP3, LAMA3, and SIK2). A large number of miRNAs participate in the regulation of hub ARGs. In addition, correlation analysis revealed that ARGs were significantly correlated with the infiltration levels of multiple immune cells in patients with KD. Innovation: We explored the expression characteristics of ARGs in KD, which is extremely important for determining the molecular pathways and mechanisms underlying KD. Conclusions: This study provides a useful reference for revealing the characteristics of ARGs in the pathogenesis of KD. The identified hub genes may provide potential therapeutic targets for patients. This study provides new ideas for individualized therapy and immunotherapy.

Abstract
Keloids (KD) and hypertrophic scars (HTS), which are quite raised and pigmented and have increased vascularization and cellularity, are formed due to the impaired healing process of cutaneous injuries in some individuals having family history and genetic factors. These scars decrease the quality of life (QOL) of patients greatly, due to the pain, itching, contracture, cosmetic problems, and so on, depending on the location of the scars. Treatment/prevention that will satisfy patients' QOL is still under development. In this article, we review pharmacotherapy for treating KD and HTS, including the prevention of postsurgical recurrence (especially KD). Pharmacotherapy involves monotherapy using a single drug and combination pharmacotherapy using multiple drugs, where drugs are administered orally, topically and/or through intralesional injection. In addition, pharmacotherapy for KD/HTS is sometimes combined with surgical excision and/or with physical therapy such as cryotherapy, laser therapy, radiotherapy including brachytherapy, and silicone gel/sheeting. The results regarding the clinical effectiveness of each mono-pharmacotherapy for KD/HTS are not always consistent but rather scattered among researchers. Multimodal combination pharmacotherapy that targets multiple sites simultaneously is more effective than mono-pharmacotherapy. The literature was searched using PubMed, Google Scholar, and Online search engines.

Abstract
Keloids are a type of abnormal scar tissue. MicroRNAs (miRNAs) exhibit a pivotal role in the regulation of cell proliferation and metastasis of keloids. miRNA microarray revealed that miR‑637 was one of the most frequently altered miRNAs in keloids. Furthermore, up-regulation of miR‑637 inhibited cell proliferation and metastasis by targeting mothers against decapentaplegic homolog (Smad)3, one of the important proteins that affects the formation of keloids. Further studies demonstrated that miR‑637 regulated the proliferation and metastasis of human keloid fibroblast (HKF) cells by mediating the Smad3 signaling pathway. Overall, the present findings suggest that miR‑637 may be a promising therapeutic target in keloids.

Abstract
Fibrosis results from the excessive accumulation of extracellular matrix in chronically injured tissue. The fibrotic process is governed by crosstalk between many signaling pathways. The search for an effective treatment is further complicated by the fact that there is a degree of tissue-specificity in the pathways involved, although the process is not completely understood for all tissues. A plethora of drugs have shown promise in pre-clinical models, which is not always borne out translationally in clinical trial. With the recent approvals of two antisense oligonucleotides for the treatment of the genetic diseases Duchenne muscular dystrophy and spinal muscular atrophy, we explore here the potential of antisense oligonucleotides to knockdown the expression of pro-fibrotic proteins. We give an overview of the generalized fibrotic process, concentrating on key players and highlight where antisense oligonucleotides have been used effectively in cellular and animal models of different fibrotic conditions. Consideration is given to the advantages antisense oligonucleotides would have as an anti-fibrotic therapy alongside factors that would need to be addressed to improve efficacy. A prospective outlook for the development of antisense oligonucleotides to target fibrosis is outlined.

Abstract
The practical use of solid lipid nanoparticles (SLNs) in research has been highlighted in the literature, but few reports have combined SLNs with miRNA-based therapy and chemotherapy. We aimed to prepare cationic SLNs (cSLNs) to load anti-miR-21 oligonucleotide and pemetrexed for glioblastoma therapy in vitro. cSLNs were employed to encapsulate both pemetrexed and anti-miR-21 by a high-pressure homogenization method, and then the properties of cSLNs were characterized. We studied cellular uptake and cytotoxicity properties of cSLNs in U87MG cells. cSLNs were 124.9 ± 1.6 nm in size and 27.3 ± 1.6 mV in zeta potential with spherical morphology in the TEM image. cSLNs uptake by U87MG cells was increased significantly higher and more effective than free pemetrexed. These findings suggest that cSLNs represent a potential new approach for carrying both pemetrexed and anti-miR-21 for glioblastoma therapy.

Fabrication of Core-Shell PLGA-Chitosan Microparticles Using Electrospinning: Effects of Polymer Concentration. INT J POLYM SCI 2017.

Abstract
This investigation aims to fabricate the core-shell microparticles composed of poly(lactic-co-glycolic acid) and chitosan (PLGA-CS MPs) using electrospinning. The challenge of using electrospinning is that it has many parameters which change product outcome if any single parameter is changed. However, the advantage of this system is that we can fabricate either micro/nanofibers or micro/nanoparticles. To learn about the effect of liquid concentration, the electrospinning parameters (voltage, needle sizes, distance from needle to collector, and ejection speed) were fixed while the concentration of PLGA or chitosan was varied. The results showed that PLGA microparticles can be fabricated successfully when the concentration of PLGA is smaller than 10 wt%. Presence of the chitosan shell was confirmed by zeta potential measurements, FT-IR, optical observation, and fluorescence observation. Thickness of the chitosan shell can be controlled by changing the concentration of chitosan and measured by fluorescamine labeling method. Moreover, SEM observation showed that concentration of chitosan affected the size of PLGA-CS microparticles. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay test showed that PLGA-CS microparticles possess excellent biocompatibility.

Abstract
Cationic lipid nanoparticles (cLNs) were modified to develop a gene delivery system for topical use via a dermal route. The cLNs were formulated using high pressure homogenization method and were composed of 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP), dioleoylphosphatidylethanolamine (DOPE), Tween 20, and tricaprin as a solid core (1:1:1:1.67, w/w). The prepared cLNs were nanoscale-sized (<100 nm) and were highly positive (51 mV). The cLN/DNA complexes demonstrated enhanced transfection potential in the cells at the optimal ratio without cytotoxic effects. To evaluate its efficacy in topical application, in vitro skin transfer of the cLN/DNA complexes was monitored using the measurement of the surface zeta potential of hairless mouse skin and validated using confocal microscopy of the sectioned skin. The in vivo delivery of plasmid DNA with the cLN formulation was examined using the relative expression levels of mRNA after non-invasive application with the cLN/DNA complexes on hair-removed dorsal skin of mice. The cLNs successfully transferred plasmid DNA to the skin, which was facilitated by the charge-mediated interaction between the cLN/DNA complexes and the skin. These results suggest the promising potential of cLNs as a topical gene delivery system for gene vaccine delivery and cutaneous gene therapy in preclinical and clinical applications.

Abstract
INTRODUCTION Keloids are fibroproliferative disorders that are characterized by histological accumulation of collagens and fibroblasts, refractory clinical symptoms such as itching, topical invasiveness, and frequent postsurgical recurrence. At present, to treat or prevent keloids, new drugs are currently being designed and the pharmaceutical indications of known drugs are being expanded. AREAS COVERED The current pharmacological interventions for keloids are mainly described on the basis of the various hypotheses on keloid etiology and the keloid ingredients that are targeted. These interventions include angiotension-converting enzyme inhibitors and calcium-channel blockers (based on hypertension hypothesis), selective estrogen receptor modulator (based on endocrinological hypothesis), vitamins and essential fatty acids (based on immunonutritional hypothesis), and transglutaminase inhibitor (based on metabolic hypothesis). Drugs that directly target the reduction or destruction of the major extracellular matrix or cellular constituents of keloids are also included. Besides, drugs that indirectly modulate the biochemical microenvironment are described. These include growth factors, immunomodulators, and anti-inflammation and anti-allergy drugs. EXPERT OPINION Due to the unclear etiology of keloids and the lack of animal models, efficient, reliable, and specific pharmaceutical interventions for keloids continue to be lacking. The reliability of current data and clinical observations must be strengthened by large-scale, randomized, controlled clinical trials.
