- Chronic kidney disease (CKD) is associated with sensorineural hearing loss, but the mechanisms linking renal injury to cochlear dysfunction remain incompletely defined. Because lipocalin-2 (LCN2/NGAL) is markedly increased in CKD and has been implicated in endothelial dysfunction and barrier injury, we investigated whether LCN2 contributes to cochlear damage in a mouse model of CKD. Male C57BL/6J mice underwent 5/6 nephrectomy, and CKD mice received either an anti-LCN2 monoclonal antibody or an isotype control three times weekly for seven weeks beginning one week after completion of surgery. Auditory function, cochlear morphology, blood-labyrinth barrier integrity, cochlear perfusion, and LCN2-associated signaling were assessed using auditory brainstem responses, distortion product otoacoustic emissions, whole-mount immunofluorescence, FITC-dextran extravasation, Western blotting, quantitative PCR, and laser Doppler flowmetry. CKD mice developed elevated auditory brainstem response thresholds, reduced distortion product otoacoustic emission amplitude at a single primary tone pair with f2 = 8.0 kHz, outer hair cell loss, and a reduction in the number of CtBP2-positive presynaptic ribbon puncta per inner hair cell. These changes were accompanied by increased serum and cochlear LCN2, upregulation of 24p3R/SLC22A17 and NLRP3, increased blood-labyrinth barrier permeability, reduced claudin-5 and ZO-1 expression, impaired cochlear blood flow, stria vascularis atrophy, and decreased expression of strial ion-transport genes. Anti-LCN2 antibody treatment improved auditory thresholds and otoacoustic emission responses, attenuated outer hair cell and synaptic injury, reduced vascular leakage, partially restored tight junction and ion-transport gene expression, and improved cochlear perfusion, without measurably lowering serum blood urea nitrogen or creatinine. These findings support a possible contribution of LCN2 to CKD-associated cochlear vascular dysfunction and hearing loss. Targeting LCN2 may represent a therapeutic strategy for preserving hearing in CKD, although validation in additional CKD models, both sexes, and human tissues is required. - Source: PubMed

Ding YeJiang XinYe Xiangming - Prostate cancer (PCa) is a hormone-dependent tumor and one of the most prevalent cancers in men worldwide. PCa progression is influenced by its interaction with the surrounding tumor microenvironment, highlighting the role of periprostatic adipose tissue (PPAT), which modulates PCa behavior through the secretion of bioactive molecules (e.g., adipokines). However, the influence of this complex cell communication, particularly under altered metabolic conditions, remains to be fully elucidated. - Source: PubMed

We employed Staurosporine to pre-induce apoptosis in bone marrow mesenchymal stem cells (BMSCs). The conditioned medium from apoptotic BMSCs was then used to pretreat β cells, which notably enhanced the suppression of β cell apoptosis. For in vivo experiments, co-transplantation of islets and apoptotic BMSCs under the renal capsule of diabetic rats inhibited islets apoptosis and resulted in better transplantation outcomes. Subsequently proteomic analysis revealed that the iron-loaded form of Lcn2 protein (holo-Lcn2) secreted by apoptotic BMSCs played a crucial role in exerting anti-apoptotic effects. Holo-Lcn2 binds to the Slc22a17 transporter on cell membrane, facilitating the transport of Fe into cells. Inhibition of Fe transport suppressed the anti-apoptotic effect of holo-Lcn2. Thus, we hypothesize that apoptotic BMSCs reduce grafted islets apoptosis through the holo-Lcn2/Slc22a17/Fe axis. This study provides insights into the application of BMSCs-based acellular therapies in islet transplantation. - Source: PubMed

Lu CuinanWang JialeWang YingWang JingwenBi HuanjingYu XiaoyangChen ZuhanDong BoqingMa RuiyangDing Xiaoming - Cancer-related pain and anxiety significantly negate the quality of life in patients. Oligodendrocyte precursor cells (OPCs) were reported to involve in engulf synapses and remodel neural circuits. This study aimed to elucidate the role of OPCs-mediated phagocytosis of GABAergic synapses in a mouse model of bone cancer pain. Male C3H mice were utilized to establish a model of bone cancer pain. In vivo fiber photometry was used to monitor the activity of GABAergic neurons, and chemogenetic techniques were applied to modulate neuronal excitation. The phagocytosis of GABAergic synapses by OPCs was visualized via immunofluorescence-based 3D reconstruction and immunoelectron microscopy. Interventions targeting lipocalin-2 (LCN2) and its receptor SLC22A17 were carried out with adeno-associated virus (AAV), siRNA, and pharmacological tools. On the 21st postoperative day, mice with bone cancer displayed significant pain and anxiety-like behaviors. Tumor-bearing mice exhibited a compensatory increase in calcium activity among GABAergic neurons within the anterior cingulate cortex (ACC). Compared with sham-operated mice, OPC phagocytosis of GABAergic synapses was higher in the tumor-bearing mice than controls. Concurrently, a pronounced upregulation of LCN2 expression was observed in the tumor group. Administration of LCN2-neutralizing antibodies or AAV-mediated intervention markedly alleviated pain and anxiety-related behaviors in mice with bone cancer. Moreover, the LCN2 receptor SLC22A17 expression was significantly increased. Targeted inhibition of SLC22A17 induced cytoskeletal remodeling and decreased their phagocytic capacity of OPCs. Collectively, LCN2/SLC22A17 signal was involved in OPCs-mediated phagocytosis of GABAergic synapses and contributed to cancer pain and anxiety development. - Source: PubMed

Recent findings from Bossowski et al. indicate that the integrated stress response (a crucial component of cellular responses against infection) can unexpectedly promote immune evasion via an LCN2-driven, macrophage-dependent mechanism. - Source: PubMed
