Excessive free fatty acid sensing in pituitary lactotrophs elicits steatotic liver disease by decreasing prolactin levels. Cell Rep 2024; 43:114465. [PMID: 38985678 DOI: 10.1016/j.celrep.2024.114465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 04/27/2024] [Accepted: 06/24/2024] [Indexed: 07/12/2024] Open
Abstract
The pituitary is the central endocrine gland with effects on metabolic dysfunction-associated steatotic liver disease (MASLD). However, it is not clear whether the pituitary responds to free fatty acid (FFA) toxicity, thus dysregulating hepatic lipid metabolism. Here, we demonstrate that decreased prolactin (PRL) levels are involved in the association between FFA and MASLD based on a liver biospecimen-based cohort. Moreover, overloaded FFAs decrease serum PRL levels, thus promoting liver steatosis in mice with both dynamic diet intervention and stereotactic pituitary FFA injection. Mechanistic studies show that excessive FFA sensing in pituitary lactotrophs inhibits the synthesis and secretion of PRL in a cell-autonomous manner. Notably, inhibiting excessive lipid uptake using pituitary stereotaxic virus injection or a specific drug delivery system effectively ameliorates hepatic lipid accumulation by improving PRL levels. Targeted inhibition of pituitary FFA sensing may be a potential therapeutic target for liver steatosis.

J Control Release 2022; 351:341-360. [PMID: 36152806 DOI: 10.1016/j.jconrel.2022.09.036] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 08/20/2022] [Accepted: 09/15/2022] [Indexed: 10/31/2022]
Abstract
Despite the tremendous theranostics potential of nano-scale drug delivery system (NDDS) in oncology field, their tumor-targeting efficiency and safety remain major challenges due to their proneness of off-target accumulation through widespread vascular endothelial gaps (up to 1 μm). To address this problem, in this research, micro-sized cellular platelet "ghosts" (PGs, 1.32 μm, platelet without inner granules and coagulation) were employed as carriers to ship hollow gold nanoparticles (HGNs, 58.7 nm), forming a hierarchical biosafe system (PG@HGNs) to reduce normal tissue interception and enhance tumor targeting delivery of HGNs for improved photothermal therapy. PGs were prepared by an optimized "swelling-extrusion-elution" method, HGNs were loaded in PGs (PG@HGNs) through a "hypotonic dialysis" method and the safety and biodistribution of the system was evaluated in vitro and in vivo. In in vitro condition that stimulated the tumoral vessel acidic microenvironment (pH = 6.5), PG@HGNs were demonstrated with enhanced membrane fluidity through down-regulation of the glycoprotein Ib expressed on the PGs. This change induced a burst release of nano-sized HGNs which were capable to traverse vascular endothelium layer on a tumor-endothelial cell transwell model, whilst the micro-sized PG carriers were intercepted. In comparison to nano-sized platelet membrane-coated carriers (PM@HGNs), PG@HGNs showed enhanced internalization and cytotoxicity to 4T1 cells. In animal models, PG@HGNs remarkably prolonged circulation most likely due to the presence of "self-recognition" receptor-CD47 of PGs, and effectively reduced normal tissue interception via the micro-scale size effect. These both contributed to the significantly improved tumor targeting efficiency of HGNs. PG@HGNs generated the greater antitumor photothermal efficacy alongside safety in the animals compared to PM@HGNs. Collectively, this study demonstrated the potential of the micro-scale PGs equipped with adjusted membrane GP Ib as biosafe vehicles for HGNs or possibly other nanodrugs. THE STATEMENT OF SIGNIFICANCE: Despite the tremendous theranostics potentials, the safety and tumor-targeting efficiency of nano-scale drug delivery systems (NDDS) are compromised by their undesirable accumulation in normal tissues with widespread vascular endothelial gaps, such as many tumor-targeted NDDSs still accumulated much in liver and/or spleen. Herein, we explored a micro-nano biomimetic cascade delivery system to address the above drawbacks. By forming a hierarchical biosafe system, micro-sized platelet "ghost" (PGs, 1.32 μm) was employed as tumor-targeted delivery carrier to transport hollow gold nanoparticles (HGNs, 58.7 nm). It was demonstrated that this micro-size system could maintain platelet membrane structure thus prolong in vivo circulation, while avoiding extravasation into normal tissues. PG@HGNs could sensitively respond to the acidic microenvironment near tumor vessel via down-regulation of glycoprotein Ib and rapidly release "nano-bullets"-HGNs to further penetrate into the tumor tissues through EPR effect, thus enhancing photothermal efficacy generated by HGNs under NIR irradiation. Collectively, the micro-scaled PGs could be biosafe vehicles for improved tumor-targeted delivery of HGNs or possibly other nanodrugs.

Abstract
Glioblastoma (GBM) is the most devastating and aggressive brain tumor in adults. Hidden behind the blood-brain and blood-tumor barriers (BBTB), this invasive type of brain tumor is not readily accessible to nano-sized particles. Here we demonstrate that fluorescent indocarbocyanine lipids (ICLs: DiD, DiI) formulated in PEGylated lipid nanoparticle (PLN) exhibit highly efficient penetration and accumulation in GBM. PLN-formulated ICLs demonstrated more efficient penetration in GBM spheroids and organoids in vitro than liposomal ICLs. Over 82% of the tumor's extravascular area was positive for ICL fluorescence in the PLN group versus 13% in the liposomal group just one hour post-systemic injection in the intracranial GBM model. Forty-eight hours post-injection, PLN-formulated ICLs accumulated in 95% of tumor myeloid-derived suppressor cells and macrophages, 70% of tumor regulatory T cells, 50% of tumor-associated microglia, and 65% of non-immune cells. PLN-formulated ICLs extravasated better than PEGylated liposomal doxorubicin and fluorescent dextran and efficiently accumulated in invasive tumor margins and brain-invading cells. While liposomes were stable in serum in vitro and in vivo, PLNs disassembled before entering tumors, which could explain the differences in their extravasation efficiency. These findings offer an opportunity to improve therapeutic cargo delivery to invasive GBM.

Abstract
Leukemia is a hematological malignancy associated with the uncontrolled proliferation of mutant progenitors, suppressing the production of normal blood cells. Current treatments, including chemotherapy, radiotherapy, and immunotherapy, still lead to unsatisfactory results with a 5 year survival rate of only 30-50%. The poor prognosis is related to both disease relapse and treatment-associated toxicity. Delivery strategies can improve the in vivo pharmacokinetics of drugs, navigating the therapeutics to target cells or the tumor microenvironment and reversing drug resistance, which maximizes tumor elimination and alleviates systematic adverse effects. This review discusses available FDA-approved anti-leukemia drugs and therapies with a focus on the advances in the development of anti-leukemia drug delivery systems. Additionally, challenges in clinical translation of the delivery strategies and future research opportunities in leukemia treatment are also included.

Abstract
Bone tissues are the main metastatic sites of many cancers, and bone metastasis is an important cause of death. When bone metastasis occurs, dynamic interactions between tumor cells and bone tissues promote changes in the tumor-bone microenvironments that are conducive to tumor growth and progression, which also promote several related diseases, including pathological fracture, bone pain, and hypercalcemia. Accordingly, it has obvious clinical benefits for improving the cure rate and reducing the occurrence of related diseases through targeting bone microenvironments for the treatment and early detection of cancer bone metastasis niches. In this review, we briefly analyzed the relationship between bone microstructures and tumor metastasis, as well as microenvironmental changes in osteoblasts, osteoclasts, immune cells, and extracellular and bone matrixes caused when metastatic tumor cells colonize bones. We also discuss novel designs in nanodrugs for inhibiting tumor proliferation and migration through targeting to tumor bone metastases and abnormal bone-microenvironment components. In addition, related researches on the early detection of bone and multi-organ metastases by nanoprobes are also introduced. And we look forward to provide some useful proposals and enlightenments on nanotechnology-based drug delivery and probes for the treatment and early detection of bone metastasis.
