- Anaplastic thyroid cancer (ATC) is a lethal malignancy characterized by therapy resistance and rapid recurrence, driven in part by a population of thyroid cancer stem cells (CSCs). While the Gli1 inhibitor GANT61 targets CSC self-renewal, its efficacy is limited by compensatory activation of the pro-survival TAK1-AMPK pathway. Our present study aims to determine whether triptolide (TPL), a natural compound that inhibits TAK1 and induces reactive oxygen species (ROS), can overcome this resistance and achieve a synergistic anticancer effect when use with GANT61. Here, we report that TPL blocked GANT61-induced TAK1-AMPK activation. TPL alone effectively inhibited the proliferation of two ATC cell lines (8505C and SW1736) and achieved a synergistic anti-proliferative effect when used in combination with GANT61. Consistently, TPL alone effectively suppressed SW1736 xenograft tumor growth but, when used in combination with GANT61, prevented tumor recurrence. TPL in combination with GANT61 synergistically inhibited thyroid CSC self-renewal and induced apoptosis and pyroptosis. Mechanistically, TPL blocked GANT61-mediated activation of the TAK1-AMPK axis and synergistically induced ROS generation, which potentiated pyroptotic activity of Gasdermin D and E (GSDMD/E). This was confirmed by the evidence that TAK1 and AMPK inhibition by gene knockout or their specific inhibitors enhanced apoptotic and pyroptotic activity of GANT61, whereas ROS scavenge blocked apoptosis and pyroptosis induced by TPL and/or GANT61. Taken together, our study provides mechanistic insights into how TPL overcomes a key resistance pathway in CSC target therapy and suggests that the TPL-GANT61 combination could be a promising strategy to eradicate ATC. - Source: PubMed

Zhang QianYe YinyanHuang YijieLi JunHuang Dongfeng - Androgenetic alopecia (AGA) involves dihydrotestosterone-driven follicular miniaturization compounded by oxidative stress and perifollicular inflammation, while current pharmacotherapies remain limited by adverse effects. Neem ( A. Juss., Meliaceae) leaves, a phenolic- and limonoid-rich plant widely used in Southeast Asian traditional medicine, were fermented for seven days with a tri-culture consortium of , , and (TRI-NE) to evaluate whether expanded microbial diversity enhances bioactivity relative to the unfermented extract (UN-NE). TRI-NE significantly increased total phenolic content, rising from 315.30 to 564.70 mg GAE/g by day 7, alongside an overall enhancement of antioxidant capacity across all assays. Moreover, untargeted metabolomics revealed compositional remodeling, with 67.47% of significantly altered metabolite features upregulated after fermentation, including selective enrichment of quercetin despite reductions in other polyphenols. In human hair follicle dermal papilla cells (HFDPCs) and complementary models, TRI-NE consistently outperformed UN-NE, enhancing paracrine-mediated fibroblast proliferation, preserving cell viability under potassium-channel blockade, suppressing lipopolysaccharide-induced inflammatory nitric oxide production, and attenuating oxidative membrane damage. At the transcriptional level, TRI-NE downregulated androgen metabolism ( and ) and pro-regression genes () while upregulating Wnt/β-catenin (), Sonic Hedgehog (, , and ), and angiogenic () pathway genes, with effects matching or exceeding standard hair-loss therapeutics. These findings indicate that TRI-NE confers superior bioactivity over the unfermented extract, supporting its potential as a multi-target cosmeceutical candidate for AGA. - Source: PubMed

The clinical course lasting 28 years confirms the indolent nature of gastroblastoma, although the disease was metastatic to local lymph nodes and peritoneum at the time of diagnosis. The tumor displayed a predominant monophasic appearance, being composed of epithelial cells with only very rare spindle mesenchymal cells, confirmed at ultrastructural examination. Thorough immunohistochemical investigation demonstrated coexpression of cytokeratins (AE1/AE3, CAM5.2, CK8/18), podoplanin (D2-40), CD56, and NSE in absence of synaptophysin, chromogranin A, DOG1, CD117, CD34, SMA, desmin, vimentin, and S100. In addition, the expression of somatostatin receptor 2 A associated with positive octreoscan and Ga-DOTATOC PET imaging may suggest the use of this nuclear medicine approach for the staging of the tumor and to select patients for possible therapy with somatostatin analogues. The tumor was mismatch repair proteins proficient and did not show any mutation in all 60 genes investigated. Interestingly, targeted RNA sequencing identified a previously unreported TAC3::GLI1 fusion that expands the spectrum of genetic aberrations of gastroblastoma. - Source: PubMed

La Rosa StefanoBranca FedericaFinzi GiovannaLibera LauraLeutner MonicaSchubart ChristophAgaimy Abbas - Renal fibrosis lacks experimentally tractable human-relevant models that integrate defined stromal programming with spatially controlled profibrotic cues. Here, we developed a dual E-/VE-cadherin-Fc (EVE) interface to condition human mesenchymal stem cells (MSCs) under CTGF/TGF-β stimulation. Cells showed increased expression of Gli-1, NG2, PDGFRβ, and FAP and activated transcription of extracellular matrix remodeling. These changes were consistent with the acquisition of a Gli-1 perivascular-like profibrotic stromal phenotype, and were accompanied by reorganization of cadherin-catenin complexes, actin cytoskeletal rearrangement, and increased YAP nuclear localization. Cell-sized PLGA/chitosan-heparin microparticles were subsequently functionalized with E-/VE-cadherin-Fc and loaded with CTGF/TGF-β. Co-assembly of these microparticles with the conditioned stromal cells (gMSCs) and renal epithelial cells (HK-2) generated 3D renal fibrotic microtissues that combined cadherin-mediated adhesive presentation with localized cytokine delivery. The resulting microtissues exhibited a broader distribution of α-SMA, Collagen I, and Fibronectin, together with reciprocal epithelial-stromal signaling and spatially organized fibrotic activation. As a proof of concept for pharmacological evaluation, the microtissues responded to pirfenidone (PFD) in a dose-dependent manner, with 100 µM PFD reducing α-SMA expression by ∼73% while preserving microtissue viability. Together, these findings establish a material-enabled, cadherin-guided strategy for constructing disease-relevant stromal organization and spatially controlled profibrotic signaling in human renal fibrosis models. - Source: PubMed
