Akt1 and Jak1 siRNA based silencing effects on the proliferation and apoptosis in head and neck squamous cell carcinoma.
In conclusion, the combination of siRNA-mediated gene-silencing strategy can be considered as a valuable and safe approach for sensitizing cancer cells to chemotherapeutic agents thus proposed further studies regarding this issue to approve some siRNA based therapeutics for using in clinic.

Mutation-Targeted siRNA Therapy for Connexin 26-Associated Keratitis-Ichthyosis-Deafness Syndrome
ConclusionTo that end, a KID syndrome cell line (KID-KC) was established from primary keratinocytes of a KID syndrome patient with heterozygous p.D50N mutation, which displayed impaired gap junction intercellular communication and hyperactive hemichannels, confirmed by dye transfer, patch clamp and neurobiotin uptake assays. In KID-KCs, treatment with AS-siRNA led to robust inhibition of the mutant GJB2 allele without altering expression of the wildtype allele. This resulted in correction of both gap junction intercellular communication and hemichannel activity. Furthermore, AS-siRNA treatment caused only low-level off-tar...

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

SOCS and Herpesviruses, With Emphasis on Cytomegalovirus Retinitis
Christine I. Alston1,2 and Richard D. Dix1,2* 1Department of Biology, Viral Immunology Center, Georgia State University, Atlanta, GA, United States 2Department of Ophthalmology, Emory University School of Medicine, Atlanta, GA, United States Suppressor of cytokine signaling (SOCS) proteins provide selective negative feedback to prevent pathogeneses caused by overstimulation of the immune system. Of the eight known SOCS proteins, SOCS1 and SOCS3 are the best studied, and systemic deletion of either gene causes early lethality in mice. Many viruses, including herpesviruses such as herpes simplex virus and cytomega...

Current non-viral siRNA delivery systems as a promissing treatment of skin diseases.
CONCLUSION: The treatment of skin diseases based on topical delivery of siRNA, which act by inhibiting the expression of target transcripts, offers many potential therapeutic advantages for suppressing genes into the skin. PMID: 30084329 [PubMed - as supplied by publisher]

Slug inhibition increases radiosensitivity of oral squamous cell carcinoma cells by upregulating PUMA.
This study aims to investigate whether the modulation of Slug expression by siRNA affects oral squamous cell carcinoma sensitivity to X-ray irradiation through upregulating PUMA. Two oral squamous cell carcinoma cell lines (HSC3 and HSC6) were transfected with small interfering RNA (siRNA) targeting Slug and subjected to radiotherapy in vitro. After transfection with Slug siRNA, both HSC3 and HSC6 cells showed relatively lower expression of Slug and higher expression of PUMA. The Slug siRNA transfected cells showed decreased survival and proliferation rates, an increased apoptosis rate and enhanced radiosensitivity to X-r...

Plasmid-Based Stat3 siRNA Delivered by Functional Graphene Oxide Suppresses Mouse Malignant Melanoma Cell Growth.
Authors: Yin D, Li Y, Guo B, Liu Z, Xu Y, Wang X, Du Y, Xu L, Meng Y, Zhao X, Zhang L Abstract RNA interference (RNAi) has been used for cancer gene therapy in recent years. However, the application of RNAi is hindered in the absence of safe and efficient gene delivery. In this article, a novel vehicle of graphene oxide functionalized with polyethylenimine and polyethylene glycol (GO-PEI-PEG) was successfully synthetized and then used to deliver plasmid-based Stat3 siRNA. The carrier can readily bind plasmid with high transfection efficiency. Moreover, molecular biology studies reveal that Stat3-related gene and pr...

Downregulation of PLK1 by RNAi attenuates the tumorigenicity of esophageal squamous cell carcinoma cells via promoting apoptosis and inhibiting angiogenesis.
Abstract Polo-like kinase 1(PLK1) is essential for the maintenance of genomic stability during mitosis. PLK1 has been reported to be upregulated in several solid tumors, including esophageal squamous cell carcinoma (ESCC). However, the role of PLK1 in tumorigenesis of ESCC remains undetermined. We used siRNA and lentivirus-mediated PLK1 RNA interference to investigate the tumor suppressor function of PLK1 reduction in ESCC cells. Flow cytometry and Terminal deoxynuleotidyl transferase-mediated nick-end labeling assay in vitro, as well as immunohistochemitry analysis of Caspase-3 and CD31 in s.c. tumor tissue secti...

Efficient in vitro gene therapy with PEG siRNA lipid nanocapsules for passive targeting strategy in melanoma.
The objective of this work consists in formulating and optimizing the encapsulation of siRNA into lipid nanocapsules (LNCs) for efficient gene therapy on melanoma cells. SiRNA LNCs were prepared from DOTAP/DOPE lipoplexes, and the siRNA dose and lipid/siRNA charge ratio were assayed to improve the stability and encapsulation yield. Cryo-TEM imaging of the siRNA lipoplexes and LNC morphology revealed a specific organization of the siRNA DOTAP/DOPE lipoplexes as well as specific lipid microstructures. No cytotoxicity of the siRNA LNCs against the melanoma SK-Mel28 cell line was observed at concentrations of up to 500 ng/mL s...
