Conclusions CG may be a safe and effective adjuvant in the treatment of symptomatic knee OA.Squamous cell carcinoma (SCC) is an aggressive malignancy that can originate from various organs. TP63 is a master regulator that plays an essential role in epidermal differentiation. It is also a lineage-dependent oncogene in SCC. ΔNp63α is the prominent isoform of TP63 expressed in epidermal cells and SCC, and overexpression promotes SCC development through a variety of mechanisms. Recently, ΔNp63α was highlighted to act as an epidermal-specific pioneer factor that binds closed chromatin and enhances chromatin accessibility at epidermal enhancers. ΔNp63α coordinates chromatin-remodeling enzymes to orchestrate the tissue-specific enhancer landscape and three-dimensional high-order architecture of chromatin. Moreover, ΔNp63α establishes squamous-like enhancer landscapes to drive oncogenic target expression during SCC development. Importantly, ΔNp63α acts as an upstream regulator of super enhancers to activate a number of oncogenic transcripts linked to poor prognosis in SCC. Mechanistically, ΔNp63α activates genes transcription through physically interacting with a number of epigenetic modulators to establish enhancers and enhance chromatin accessibility. In contrast, ΔNp63α also represses gene transcription via interacting with repressive epigenetic regulators. ΔNp63α expression is regulated at multiple levels, including transcriptional, post-transcriptional, and post-translational levels. In this review, we summarize recent advances of p63 in epigenomic and transcriptional control, as well as the mechanistic regulation of p63.The membrane lipids diacylglycerol (DAG) and phosphatidic acid (PA) are important second messengers that can regulate membrane transport by recruiting proteins to the membrane and by altering biophysical membrane properties. DAG and PA are involved in the transport from the Golgi apparatus to endosomes, and we have here investigated whether changes in these lipids might be important for regulation of transport to the Golgi using the protein toxin ricin. Modulation of DAG and PA levels using DAG kinase (DGK) and phospholipase D (PLD) inhibitors gave a strong increase in retrograde ricin transport, but had little impact on ricin recycling or degradation. Inhibitor treatment strongly affected the endosome morphology, increasing endosomal tubulation and size. Furthermore, ricin was present in these tubular structures together with proteins known to regulate retrograde transport. Using siRNA to knock down different isoforms of PLD and DGK, we found that several isoforms of PLD and DGK are involved in regulating ricin transport to the Golgi. Finally, by performing lipidomic analysis we found that the DGK inhibitor gave a weak, but expected, increase in DAG levels, while the PLD inhibitor gave a strong and unexpected increase in DAG levels, showing that it is important to perform lipidomic analysis when using inhibitors of lipid metabolism.Fetal hemoglobin (HbF) ameliorates clinical severity of sickle cell anemia (SCA). The major loci regulating HbF levels are HBB cluster, BCL11A, and HMIP-2 (HBS1L-MYB). However, the impact of noncoding single-nucleotide polymorphisms (SNPs) in these loci on clinical outcomes and their functional role on regulating HbF levels should be better elucidated. Therefore, we performed comprehensive association analyses of 14 noncoding SNPs in five loci with HbF levels and with clinical outcomes in a cohort of 250 children with SCA from Southeastern Brazil, and further performed functional annotation of these SNPs. We found SNPs independently associated with HbF levels rs4671393 in BCL11A (β-coefficient = 0.28), rs9399137 in HMIP-2A (β-coefficient = 0.16), and rs4895441 in HMIP-2B (β-coefficient = 0.15). Patients carrying minor (HbF-boosting) alleles for rs1427407, rs93979137, rs4895441, rs9402686, and rs9494145 showed reduced count of reticulocytes (p 1.3; p ≤ 0.01). Carriers of the reference allele for rs4671393 showed lower risk of infections (IRR = 1.16; p = 0.01). In conclusion, patients carrying HbF-boosting alleles of BCL11A and HMIP-2 were associated with milder clinical phenotypes. Higher HbF concentration may underlie this effect.Raynaud's phenomenon is a vasospastic condition affecting hands and feet which may lead to rest pain, ischemic ulcers and gangrene. Botulinum toxin A has been shown to improve peripheral circulation and relieve vasospastic symptoms. Our aim was to assess our treatment outcomes following Botulinum toxin A injections in patients with Raynaud's phenomenon and to explore the importance of toxin concentration and injection sites. Retrospective chart review of patients with primary and secondary Raynaud's syndrome treated with Botulinum toxin A injections and a literature review was conducted. The toxin dose, injection sites, symptom relief, healing of ulcers and complications were assessed. A total of 30 treatment episodes over a 7½ year period were included. All patients had failed medical management. Botulinum toxin A injection was injected primarily in the vicinity of the palmar digital neurovascular bundle. The average total Botulinum toxin A dose injected was 156 U and the concentration was 50 U/ml. All patients reported an improvement in symptoms and healing of digital ulcers. One patient reported a temporary muscle weakness. Six patients had a single treatment episode with long term benefit. HSP (HSP90) modulator Systemic sclerosis patients had an average of 6-month interval between treatment episodes. Higher doses of Botulinum toxin A has been well tolerated with no long term adverse effects. Our study shows that targeted low volume higher concentration Botulinum toxin A injections are effective in treating Raynaud's phenomenon.To assess the modalities and current practices in gout management reported by Moroccan rheumatologists. We performed a cross-sectional online survey using a questionnaire e-mailed to 360 rheumatologists included 30 multiple-choice questions. 105 rheumatologists responded to the survey with 29% of response rate. The number of gout patients seen per month was five (3-9); they were referred in 58.7% by a general practitioner. The clinical presentation of gout patients was dominated by gout crisis in 71%, and the association gout crisis and gouty arthropathy accounted for 19% of severe forms. 40% of rheumatologists apply the 2015ACR/EULAR classification criteria. Obesity accounted for 85.7% of the associated comorbidities. The most commonly prescribed Urate-lowering therapy (ULT) was allopurinol in 81.3% (± 12). 48% of rheumatologists reported starting allopurinol at 200 mg daily and associated it with colchicine during the first 6 months by 33.3%. The determination of uric acid levels was monitoring in 76.2% every 3 months.
