GSEA demonstrated that POU2F3 is associated with the c-MYC/p53 signaling pathway and metastasis. POU2F3 knockdown reversed the inhibitory effect of ISL on the growth and metastasis of melanoma. Additionally, POU2F3 was found to be downregulated in melanoma tissue samples and was negatively correlated with miR-27a. ISL inhibits proliferation and metastasis of melanoma via the miR-27a/POU2F3/c-MYC/p53 axis; these results may provide a new thought for the treatment of melanoma.ISL inhibits proliferation and metastasis of melanoma via the miR-27a/POU2F3/c-MYC/p53 axis; these results may provide a new thought for the treatment of melanoma.Betacoronaviruses are in one genera of coronaviruses including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome-related coronavirus (MERS-CoV), etc. These viruses threaten public health and cause dramatic economic losses. The nucleocapsid (N) protein is a structural protein of betacoronaviruses with multiple functions such as forming viral capsids with viral RNA, interacting with viral membrane protein to form the virus core with RNA, binding to several cellular kinases for signal transductions, etc. In this review, we highlighted the potential of the N protein as a suitable antiviral target from different perspectives, including structure, functions, and antiviral strategies for combatting betacoronaviruses.Atherosclerosis is the primary culprit of cardiovascular and cerebrovascular diseases. Also, atherogenesis and the development of atherosclerosis involve endothelial cells, monocytes/macrophages, smooth myocytes, and others. Increasingly, studies have found that non-coding RNA (ncRNA) which can regulate apoptosis, pyroptosis, autophagy, proliferation, and monocyte migration participates in atherogenesis and progress of atherosclerosis by the above. The ncRNA networks may be essential in regulating the complicated process of atherosclerosis. Accordingly, this review delves into the regulatory roles of ncRNA, which were introduced previously. The answer above is particularly crucial to explain further the regulatory mechanism of ncRNA in cardiovascular disorders. Furthermore, we discuss the possibility and related research of ncRNAs as a biomarker and therapeutic target for the prevention, diagnosis, and treatment of atherosclerosis.Although used in a wide range of medical and pharmaceutical applications, the potential of the natural biopolymer bacterial nanocellulose (BNC) as drug delivery system is by far not fully exploited. Particularly, the incorporation of lipophilic drugs is still considered as an unsolved task. In the present study, the homogeneous incorporation of the lipophilic coenzyme Q10 (CoQ10) into BNC was accomplished by several post-synthesis techniques utilizing different nanoemulsions and liposomes. All colloidal carriers were in the range of about 90-120 nm with negative zeta potentials and storage stabilities up to 30 days. The biphasic drug release profiles of loaded BNC were found to be dependent on the type of colloidal carrier and the loading technique. 8-Cyclopentyl-1,3-dimethylxanthine order Favorable characteristics such as high mechanical stability and high loading capacity were retained after the incorporation of the lipophilic components. Penetration studies using excised porcine skin revealed CoQ10 distributions also in deeper skin layers dependent on the type of the colloidal carrier system. In conclusion, hydrophilic BNC could be loaded with water-insoluble drugs as shown for the model drug CoQ10 by the use of lipidic colloidal carriers which offers new possibilities of application in pharmacy and medicine.Fluorometholone is a widely used anti-inflammatory ophthalmic formulation, which elicits a lower ocular hypertensive response than other glucocorticoid medications. This serves to mitigate against the risk of steroid-induced glaucoma. Based on the hypothesis that an improved corneal permeability can increase the bioavailability of a drug, we sought to obtain fluorometholone in suspension with a small particle size. Accordingly, we describe the formulation of fluorometholone nanocrystal eye drops, which have a mean particle size of 201.2 ± 14.1 nm (standard deviation (s.d.)) when measured by dynamic light scattering. Scanning electron microscopy further indicates that fluorometholone nanocrystals are predominantly rectangular in shape. Fluorometholone microcrystals, on the other hand, with a mean particle size of 9.24 ± 4.51 µm (s.d.), tend to have a rod-like morphology. Powder x-ray diffraction revealed that fluorometholone microcrystal and nanocrystal formulations have the same crystal structure, with the main diffraction peaks at 2θ = 10.4 and 15.3°. The nanocrystal formulation was found to be stable, long-term, when stored at 10 °C for up to 6-months. High pressure liquid chromatography (HPLC) of the aqueous humor of rabbit eyes 15-240 mins after the in vivo application of fluorometholone eye drops to the ocular surface revealed that the molecule had been converted to 20α-dihydrofluorometholone (with no evidence of a 20β-dihydrofluorometholone fraction), and that penetration was 2-6 fold higher and longer lasting with the nanocrystal, rather than the microcrystal, formulation. In current study we show how newly generated fluorometholone nanocrystals when administered as eye drops enter the anterior chamber of the eye and become metabolized to dihydrofluorometholone.Amorphous solid dispersion (ASD) has become an attractive strategy to enhance solubility and bioavailability of poorly water-soluble drugs. To facilitate oral administration, ASDs are commonly incorporated into tablets. Disintegration and drug release from ASD tablets are thus critical for achieving the inherent solubility advantage of amorphous drugs. In this work, the impact of polymer type, ASD loading in tablet and polymer-drug ratio in ASD on disintegration and drug release of ASD tablets was systematically studied. Two hydrophilic polymers PVPVA and HPMC and one relatively hydrophobic polymer HPMCAS were evaluated. Dissolution testing was performed, and disintegration time was recorded during dissolution testing. As ASD loading increased, tablet disintegration time increased for all three polymer-based ASD tablets, and this effect was more pronounced for hydrophilic polymer-based ASD tablets. As polymer-drug ratio increased, tablet disintegration time increased for hydrophilic polymer-based ASD tablets, however, it remained short and largely unchanged for HPMCAS-based ASD tablets.
