Autologous transplantation of P63+ lung progenitor cells in patients with bronchiectasis: a randomized, single-blind, controlled trial

Project description:Non-cystic fibrosis bronchiectasis is a severe respiratory disease characterized by progressive loss of lung function, resulting in high morbidity and even early mortality. Current treatments cannot repair progressive lung damage, which encouraged the exploration of stem and progenitor cell-based regenerative therapies. In current study, we found that the P63+ progenitor cells normally located in airway basal layer could appear in the alveolar spaces of bronchiectasis patients. We successfully cloned and expanded the progenitor cells from the airway brushing tissues of patients. Then we conducted a randomized, single-blind, controlled, phase 1/2 trial to evaluate the safety and efficacy of autologous P63+ progenitor cells transplantation in bronchiectasis patients.

Autologous transplantation of P63+ lung progenitor cells for chronic obstructive pulmonary disease therapy

Project description:Adult lung resident stem/progenitor cells, including P63+ progenitor cells, have demonstrated the capacity for regeneration of lung epithelium in precinical models. Here we report a clinical trial of intra-pulmonary P63+ progenitor cell transplantation which included 28 participants with chronic obstructive pulmonary disease (COPD) (stage II~IV). For control group, standard of care (SOC) for COPD treatment was given. For intervention group, in addition to SOC, autologous P63+ progenitor cells were isolated from the airway basal layer via bronchoscopic brushing, cultured for 3~5 weeks, and then transplanted into the lungs via bronchoscopy with 0.7-5.2x10^6 cells per kilogram bodyweight. Eventually 20 patients were evaluated (intervention group n=17; control group n=3). No grade 3~5 adverse events (AE) or serious adverse events occurred in any group. Bronchoscopy-associated AEs were recorded only in intervention groups, while the other AEs were recorded in both groups without showing significant difference. Participants in intervention group displayed significant improvement in diffusing capacity of the lung for carbon monoxide (DLCO) (change from baseline, 24 weeks: +18.2%), showing significant difference comparing to control group (change from baseline, 24 weeks: -17.4%)(p-value=0.008). Furthermore, more participants in intervention group showed > 30 m increase in walking distance within 6 minutes, demonstrating significant difference comparing to control group (p-value=0.036). Transcriptomic analysis of cells isolated from responding and non-responding individuals in the intervention group showed that higher expression of P63 and Nkx homeobox-1 was associated with better efficacy. In conclusion, transplantation of cultured P63+ lung progenitor cells was safe and represented a potential treatment strategy for COPD.

Effects of Gut Microbiota Manipulation by Antibiotics on Host Metabolism in Obese Humans: a Randomized Double-blind Placebo-controlled Trial

Project description:The gut microbiota has been implicated in obesity and cardiometabolic diseases, although evidence in humans is scarce. We investigated how gut microbiota manipulation by antibiotics (7-day administration of amoxicillin, vancomycin, or placebo) affects host metabolism in 57 obese, prediabetic men. Vancomycin, but not amoxicillin, decreased bacterial diversity and reduced Firmicutes involved in short-chain fatty acid and bile acid metabolism, concomitant with altered plasma and/or fecal metabolite concentrations. Adipose tissue gene expression of oxidative pathways was upregulated by antibiotics, whereas immune-related pathways were downregulated by vancomycin. Antibiotics did not affect tissue-specific insulin sensitivity, energy/substrate metabolism, postprandial hormones and metabolites, systemic inflammation, gut permeability, and adipocyte size. Importantly, energy harvest, adipocyte size, and whole-body insulin sensitivity were not altered at 8-week follow-up, despite a still considerably altered microbial composition, indicating that interference with adult microbiota by 7-day antibiotic treatment has no clinically relevant impact on metabolic health in obese humans. This randomized, placebo-controlled, double-blind study had a 3-armed parallel design. Overweight/obese participants were randomized to oral intake of amoxicillin, vancomycin or placebo for 7 consecutive days. After an overnight fast, subcutaneous adipose tissue biopsies were taken that were subjected to gene expression profiling by array.

Ropinirole hydrochloride identified by iPSC drug discovery for amyotrophic lateral sclerosis: a single-centered, randomized, double-blind, placebo-controlled phase 1/2a trial

Project description:We assessed the safety and efficacy of ropinirole, a candidate drug for amyotrophic lateral sclerosis (ALS) identified using induced pluripotent stem cells (iPSCs) technology, by a randomized controlled trial (UMIN000034954). Twenty participants were randomly assigned to ropinirole or placebo for 24 weeks in the double-blind period, followed by a 24-week open-label active extension period. Primary outcomes were safety and tolerability. Secondary outcomes evaluated the therapeutic effects of ropinirole. Adverse events were mostly those previously reported, with similar rates in both groups. Participants in the ropinirole group had lived an additional 27.9 weeks without disease progression compared with the placebo group at 12 months. We validated and confirmed the efficacy of ropinirole in patients with ALS using the largest publicly available real-world registry database of ALS (PRO-ACT). The iPSCs-derived motor neurons from the participants showed the D2R expression and the potential involvement of the SREBP2-cholesterol synthetic pathway in the therapeutic effects.

Chromatin modification is not a prerequisite for p63 binding but p63 binding can elicit chromatin remodeling

Project description:Transcription factor (TF) p63 is a master regulator playing critical roles in epidermal development and other cellular processes. Our lab’s previous research deciphered a distinct chromatin architecture at p63 bound site in keratinocytes. In order to figure out whether those chromatin modifications already exist before p63 binding, or p63 occupancy contributes to such chromatin marks, we built p63-expressing cell lines. We then obtained p63 bound regions in these overexpressing cell line, and looked at different histone marks at those sites before p63 occupancy. As shown in the results, before p63 binding, the targeting sites have barely detectable histone marks, indicating p63’s capability to approach unmodified chromatins. Moreover, there is no significant difference in chromatin marks between p63 bound sites and unbound sites when no p63 binding happens. Our in vivo findings were confirmed by examining p63 binding to unmodified nucleosomes in vitro, showing that histone modification is not indispensable for p63 binding but binding site positioning on nucleosome does play a role. Overall, our results suggest that histone modifications do not affect p63 binding, and p63 protein can bind to inaccessible, weakly modified chromatin regions in vivo.

Gene expression and biological pathways in tissue of men with prostate cancer in a randomized clinical trial of lycopene and fish oil

Project description:Animal and epidemiological studies suggest that lycopene and fish oil may modify the risk or delay progression of prostate cancer, however, the molecular mechanisms involved are poorly understood. We examined the effects of these micronutrients on prostate gene expression in a double-blind placebo-controlled randomized clinical trial (Molecular Effects of Nutritional Supplements, MENS).
