Transcriptomic profiling of RAW264.7 treated by FAPD10-exos.

ABSTRACT: Skeletal muscle maintains remarkable regenerative ability after injury, which mainly depends on the coordination and dynamic regulation between muscle stem cells and various other cell types. Recent studies have shown that fibro/adipogenic progenitors (FAP) play an important role in skeletal muscle regeneration by coordinating the interaction between muscle stem cells and macrophages. At present, the mechanism of whether FAP cells can regulate macrophages to affect skeletal muscle regeneration remains unclear. By isolation of mouse skeletal muscle FAP cells damaged by CTX for 10 days and gathered exosomes from them called FAPD10-exos, and using the exosomes to induce macrophages in vitro, we found that they expressed high levels of M2-type factors.In summary, we believe that FAPD10-exos can promote the polarization of macrophages towards M2 phenotype by secreting exosomes, and participate in and promote the regulation and regulation of skeletal muscle regeneration to enter the stage of damage repair in the early stage of regeneration.

ADSC-Exos can improve acute lung injury by regulating alveolar macrophage polarization through IRF7/NLRP3

Project description:Alveolar macrophages (AMs) are crucial for pulmonary defense and immune regulation. Exosomes from adipose-derived mesenchymal stem cells (ADSC-Exos) have emerged as a promising therapy for inflammatory lung diseases by modulating immune responses. This study investigates the ability of ADSC-Exos to alleviate inflammation in acute lunag injury (ALI), a condition often triggered by sepsis and characterized by lung permeability and respiratory failure.

miRNA expression profiles of exosomes from polarized bone marrow derived macrophages

Project description:Unprogrammed macrophage polarization, is associated with diabetic wound ulcers. Nevertheless, development of corresponding drugs is still a challenge. Here, exosomes are isolated from naive bone marrow-derived macrophages (BMDMs) (M0-Exos), inflammatory BMDMs (M1-Exos), and anti-inflammatory BMDMs (M2-Exos), with the aim of pinpointing the exosomes functionality and identify global miRNAs expression profiles.

RNA-seq analysis after MIR4435-2HG knockdown in HemECs

Project description:Infantile hemangiomas (IHs) are commonly observed benign tumors that can cause serious complications.In this study, we investigated the role of M2 macrophage-derived exosomal lncRNA MIR4435-2HG in IHs. Exosomes derived from M2 polarized macrophages were extracted. Next, using cell co-culture or transfection, we investigated whether M2 polarized macrophage-derived exosomes (M2-exos) can transport MIR4435-2HG to regulate the proliferation, migration, invasion, and angiogenesis of hemangioma-derived endothelial cells (HemECs). RNA-seq and RNA pull-down assays were performed to identify targets and regulatory pathways of MIR4435-2HG. We explored the possible mechanisms through which MIR4435-2HG regulates the biological function of HemECs.We found that M2-exos significantly enhanced the proliferation, migration, invasion, and angiogenesis of HemECs. Thus, HemECs uptake M2-exos and promote biological functions through the inclusion of MIR4435-2HG. RNA-seq and RNA pull-down experiments confirmed that MIR4435-2HG regulates of HNRNPA1 expression and directly binds to HNRNPA1, consequently affecting the NF-κB signal pathway.In conclusion, MIR4435-2HG of M2-exos promotes the progression of IHs and enhances the proliferation, migration, invasion, and angiogenesis of HemECs by directly binding to HNRNPA1. This study not only reveals the mechanism of interaction between M2 macrophages and HemECs, but also provides a promising therapeutic target for IHs.

Skewed macrophage polarization in aging skeletal muscle

Project description:Skeletal muscle aging is a major causative factor for disability and frailty in the elderly. Recent theories about the origins of the progressive impairment of skeletal muscle with aging emphasize a disequilibrium between damage and repair. Macrophages participate in muscle tissue repair first as pro-inflammatory M1 subtype and then as M2 anti-inflammatory subtype. However, information on macrophage presence in skeletal muscle is still sporadic and the effect of aging on different phenotypes remains unknown. In this study, we sought to characterize the polarization status of macrophages human skeletal muscle at different ages. We found that most macrophages in human skeletal muscle are M2, and that this number increased with advancing age. On the contrary, M1 macrophages decline with aging, making the total number of macrophages invariant with older age. Notably, M2 macrophages co-localized with increasing intermuscular adipose tissue (IMAT) in aging skeletal muscle. The mouse strain BALB/c, intrinsically M2-prone, showed increased IMAT and regenerating myofibers in skeletal muscle, accompanied by elevated expression of adipocyte markers and M2 cytokines. Collectively, we report that polarization of macrophages to the major M2 subtype is associated with IMAT, and propose that increased M2 in aged skeletal muscle may reflect active repair of aging-associated muscle damage.

Osr1 controls the pro-regenerative response of Fibro-Adipogenic Progenitors

Project description:Purpose: To study the requirement of Osr1 expression for FAP function during skeletal muscle regeneration. Methods: We sequenced total mRNAs isolated from adult FAPs FACS sorted from 3 and 7 day post injured hindlimb skeletal muscle of Ctrl (Osr1flox/+ CAGG Cre+) and Osr1 cKO (Osr1flox/flox CAGG Cre+) mice. Results: Loss of Osr1 leads to pro-fibrotic orientation of FAPs and impairs both FAP-macrophage and FAP-MuSCs communication network resulting in impaired regenerative myogenesis and persistent fibrosis. Conclusions: Osr1 is a key transcriptional regulator of FAP regenerative function protecting FAPs from assuming a detrimental pro-fibrotic and anti-myogenic state.

Profiling of mouse Fibro/adipogenic progenitors (FAPs) aging and activation upon skeletal muscle injury

Project description:Utilizing glycerol intramuscular injections in M. musculus provides a model of skeletal muscle damage followed by skeletal muscle regeneration. In particular, glycerol-induced muscle injury triggers accute activation of muscle Fibro/Adipogenic Progenitors, also called FAPs. However, aging dramatically impairs FAP function. We characterized genome-wide expression profiles of young and old FAPs in the non-proliferative and activated state, freshly isolated to non-injured or damaged muscles, respectively. Our goal was to uncover new regulatory signalings specific to FAP entry into the activation program that are affected with age.

Endothelial cells control muscle regeneration through angiocrine lactate

Project description:We studied metabolic angiocrine mechanisms by which endothelial cell_ECs_ can contribute to muscle regeneration from ischemia by using endothelial specific pfkfb3 knockout mice_pfkfb3DEC_ after hind-limb ischemia_HLI_. During muscle regeneration, monocytes are recruited to the injured area and rapidly become macrophages which initially exhibit a more pro-inflammatory M1-like phenotype but soon thereafter functionally repolarize towards an M2-like phenotype to actively support muscle regeneration. Interestingly, macrophages derived from pfkfb3DEC failed to polarized to M2-like macrophages after HLI. Reduced macrophage polarization impairs angiogenesis and muscle regeneration. The RNAseq data are pfkfb3DEC and pfkfb3WT muscle derived macrophages 3 days after HLI.

Transcriptomic analysis and fusion gene identification of Exos, MPs, MBRs

Project description:Previously, we reported that human primary (SW480) and metastatic (SW620) colorectal (CRC) cells secrete (shed) midbody remnants (MBRs), exosomes (Exos), and microparticles (MPs) are molecularly distinct at the protein level. To gain further biochemical insights into MBRs, Exos, and MPs and their emerging role in CRC, we performed, and report here for the first time, a comprehensive transcriptome and long noncoding RNA sequencing analysis and fusion gene identification of these three EV classes using the next-generation RNA sequencing technique. Differential transcript expression analysis revealed that MBRs have a distinct transcriptomic profile compared to Exos and MPs with a high enrichment of mitochondrial transcripts lncRNA/pseudogene transcripts that are predicted to bind to ribonucleoprotein complexes, spliceosome and RNA/stress granule proteins. A salient finding from this study is a high enrichment of several fusion genes in MBRs compared to Exos, MPs and cell lysates from their parental cells such as MSH2 (gene encoded DNA mismatch repair protein MSH2). This suggests potential EV-liquid biopsy targets for cancer detection. Importantly, the expression of cancer progression-related transcripts found in EV classes derived from SW480 (EGFR) and SW620 (MET and MACCA1) cell lines reflects their parental cell types. Our study is the first discovery of RNA and fusion gene compositions within MBRs (including Exos and MPs) that could have an impact on EV functionality in cancer progression and detection using EV-based RNA/ fusion gene candidates for cancer biomarkers
