Chronic stress disrupts hepatic homeostasis and accelerates liver cancer progression through ADRB2 signaling

ABSTRACT: Chronic stress has been implicated in the dysregulation of immunological, neurochemical, and endocrinological functions, yet its impact on hepatic homeostasis and liver carcinogenesis remains elusive. In this study, by employing single-nucleus RNA sequencing and histopathological evaluation, we demonstrated that chronic stress induced profound hepatic dysfunction. Strikingly, using orthotopic murine models of liver cancer, we further found that chronic stress significantly accelerated tumor progression. Mechanistically, we identified β2-adrenergic receptor (ADRB2) signaling as the pivotal molecular pathway driving stress-accelerated cancer progression, which was in line with the poor clinical outcomes observed in cancer patients exhibiting enhanced adrenergic signaling within tumors. Collectively, our study provides compelling evidence that chronic stress compromises hepatic homeostasis and accelerates liver cancer progression via ADRB2 activation, highlighting the therapeutic potential of targeting this pathway and the clinical importance of stress management in hepatic disorders.

Chronic stress disrupts hepatic kynurenine pathway to subvert hepatic CD8+ T cell immunity and promote liver cancer

Project description:Chronic psychological stress is associated with liver disease mortality, yet the reasons are unclear. Here we describe a stress-responsive brain-liver regulatory circuit that impairs CD8+T cell immunity and promotes the progression of liver cancer. Specifically, psychological stress-mediated dysregulation of catecholamine/β2-adrenergic receptor (ADRB2) signaling leads to reduced number and effector functions of liver CD8+ T cells by suppressing the expression of quinolinate phosphoribosyl transferase (QPRT) in hepatocytes and shifting hepatic Kyn metabolism from de novo nicotinamide adenine dinucleotide (NAD+) synthesis to kynurenic acid (KA) production. Notably, ADRB2/QPRT expression in human hepatocytes correlates with NAD+ and KA levels, as well as CD8+T cells frequency and function in human liver tissues.

Activation of sympathetic nervous system drives dry eye onset via norepinephrine-β2-adrenergic receptor signaling in mice

Project description:Dry eye disease (DED) and sympathetic nervous system (SNS) activation have clear association with chronic environmental and psychogenic stress. However, the relationship and mechanism of SNS activation in dry eye pathogenesis remains elusive. Here we first found that the DED mice induced by chronic desiccating stress and scopolamine exhibited the SNS activation and elevated corneal norepinephrine (NE) contents. However, systemic SNS ablation with 6-OHDA and local NE depletion with DSP-4 treatment markedly alleviated the dry eye severity. More directly, topical application of NE phenocopied the dry eye syndrome in healthy mice, but not in mice with Adrb2 gene knockout, the dominant adrenergic receptor in cornea. In contrast, topical administration of selective Adrb2 antagonist ICI 118551 significantly attenuated the dry eye severity, including the increased tear secretion, improved corneal epithelial barrier function, and the reduced expressions of matrix-metalloproteinases, chemokines and inflammatory cytokines. Transcriptomic analysis and experimental validations underscored the strong links of top 10 downregulated pathways and dry eye-related inflammatory and immune responses, including TNF, NF-κB, chemokines and IL-17 signaling. Taken together, these results provide direct evidence of SNS activation in driving dry eye onset through NA-Adrb2 signaling pathway, which offers potential preventative and therapeutic approach for dry eye diseases.

Quantitative proteomics analysis of liver from CCl4 or CDAHFD induced liver fibrosis mice

Project description:Liver fibrosis is a crucial and potentially reversible stage in the progression from chronic liver diseases towards liver cirrhosis and hepatocellular carcinoma (HCC). Endoplasmic reticulum (ER) stress is closely related to hepatic stellate cells (HSCs) activation and liver fibrosis. Liver fibrosis is frequently accompanied by a global increase in hepatic protein methylation. This suggests that there may be potential unexplored connections among ER stress, protein methylation, and liver fibrosis. Therefore, this study aims to deeply elucidate whether and how the methylated modification of the ER stress key regulatory protein GRP94, thereby playing a crucial role in mediating the activation of HSCs and liver fibrosis progression.

Olanzapine suppresses mPFC-norepinephrine releasing to alleviate CLOCK-induced cancer stemness under chronic stress

Project description:We identify a new mechanism by which OLZ ameliorates chronic stress-enhanced tumorigenesis and chemoresistance. OLZ reversed chronic stress-enhanced lung tumorigenesis and anxiety-like behaviors by suppressing neuro-activity in the mPFC and reducing norepinephrine (NE) releasing. To investigate the mechanism of NE in cancer stemness we performed RNA-seq of the NCI-H1299 cells under NE treatment and found that NE activated β2-adrenoceptor (ADRB2)-mediated cAMP-PKA-CREB pathway to transactivate CLOCK that further sustains cancer stemness.

Splenic nerves NE-β2AR axis exacerbate septic acute kidney injury via modulating neutrophilic immunosuppression [RNA-seq]

Project description:Sepsis is characterized by chronic inflammation and immunosuppression, two immune states that hinder effective infection control and significantly contribute to renal pathological damage. Recent studies have underscored the crucial role of splenic neuroimmune interactions in immune response regulation. However, the precise mechanisms and functions of splenic nerve regulation of splenic immune responses in sepsis-associated acute kidney injury (SA-AKI) remain obscure. Our research suggests that preemptive Splenic Denervation in mice can mitigate sepsis-induced renal injury, while local norepinephrine injection into the spleen exacerbates sepsis-induced kidney damage in the cecal ligation and puncture (CLP) mouse model. Targeted blockade of splenic β2-adrenergic receptor signaling leads to increased survival rates and diminished renal damage in the mice treated with CLP. Subsequent experiments involving local splenic administration of Gr-1 antibodies and myeloid cell-specific conditional knockout of Adrb2 in mice validate that during sepsis, NE/β2-AR signaling can impact splenic neutrophils, fostering the progression of acute sepsis. Mechanistic inquiries reveal that splenic Adrb2 signaling boosts neutrophil PGE2 signaling through the cAMP pathway, promoting Th1 activation, diminishing local bacterial infections, and ameliorating SA-AKI. Furthermore, Blocking ADRB2 or PGE2 synthesizing signal significantly modulates the immunosuppression effect of neutrophils, promoting anti-bacterial Th1 immune response. These studies elucidate the role of splenic NE-ADRB2 signaling in regulating neutrophil immunosuppressive functions, thereby influencing the advancement of sepsis and renal tissue damage.

Platelets accelerate endoplasmic reticulum stress and promote hepatic steatosis in mice

Project description:Background: Metabolic dysfunction-associated steatotic liver disease (MASLD), the most common chronic liver disease, is characterized by endoplasmic reticulum (ER) stress, which impairs hepatic lipoprotein metabolism. Platelets, which can modulate cellular responses to ER stress, accumulate in the liver during MASLD and contribute to disease development by interacting with liver-resident (immune) cells. Since the role of platelets in modulating hepatic ER stress in vivo is completely unknown, this study aims to investigate their effects on hepatic ER stress and steatosis. Methods/Results: Using C57BL/6 mice, we demonstrate that hepatic ER stress leads to the accumulation and activation of platelets. Depletion of platelets decreased ER stress-induced liver steatosis, indicated by reduced liver triglyceride levels. Mechanistically, we found that platelet depletion ameliorated the initial ER stress response and increased the influx of neutrophils into the liver. Inhibiting the platelet-specific receptor glycoprotein 1bα (GPIbα) partly mimicked the effects of platelet depletion, leading to impaired hepatic platelet recruitment and reduced triglyceride accumulation. Conclusion: This study demonstrates a new role of platelets in hepatic ER stress and the concomitant effect on hepatic steatosis.
