However, the outcomes remain inconclusive. Given that the tumor-intrinsic response to interferon-γ (IFN-γ) is a key determinant of immunotherapy efficacy, we investigated whether and how glutamine deprivation in cancer cells affects their response to IFN-γ. By using human lung cancer cell lines, patient-derived tumor explants, and a syngeneic mouse model of lung cancer, we demonstrated that glutamine deprivation reduced the IFN-γ-driven response in cancer cells by promoting autophagy-dependent IFN-γ receptor (IFNGR1) degradation and rendering tumors resistant to anti-PD-1 or anti-PD-L1 therapy. Treatment with V9302, an inhibitor of the alanine-serine-cysteine transporter (ASCT2), enhanced the IFN-γ-driven response of cancer cells and increased the efficacy of PD-1 blockade therapy. Mechanistic analysis revealed that V9302 inhibited autophagy by impairing lysosomal activity independent of glutamine deprivation, likely because of its physiochemical properties, thereby preventing IFNGR1 degradation. Moreover, V9302 also increased Glut1 expression through the inhibition of lysosomal pathway-dependent degradation of Glut1 and consequently increased cancer cell glucose uptake, in turn retaining the levels of intracellular alpha-ketoglutarate (α-KG) and ATP, which are involved in maintaining IFN-γ signal transduction in cancer cells. In support of these findings, targeting lysosomal activity with chloroquine (CQ) also increased IFNGR1 expression and the IFN-γ-driven response in cancer cells. The administration of CQ increased the sensitivity of ASCT2-deficient tumors to anti-PD-L1 therapy. Glutamine deprivation per se leads to resistance to immunotherapy, whereas V9302 treatment results in increased immunotherapy efficacy through impaired lysosomal activity, which is independent of glutamine deprivation.</div></div>","PeriodicalId":19918,"journal":{"name":"Pharmacological research","volume":"213 ","pages":"Article 107643"},"PeriodicalIF":9.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143256321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study their functional role in regulating specific receptor systems, current research relies mainly on genetic tools, as few pharmacological options are available. To address this issue, we designed and synthesised a novel lipidated phosphomimetic peptide inhibitor targeting β-arrestins, called ARIP, which was developed based on the C-terminal tail (A343-S371) of the vasopressin V2 receptor. As the V2R sequence has been shown to bind β-arrestins with high affinity, we added an N-terminal palmitate residue to allow membrane tethering and cell entry. Here, using BRET²-based biosensors, we demonstrated the ability of ARIP to inhibit agonist-induced β-arrestin recruitment on a series of 7TMRs that includes both stable and transient β-arrestin binders, with efficiencies that depend on receptor type. In addition, we showed that ARIP was unable to recruit β-arrestins to the cell membrane by itself, and that it did not interfere with G protein signalling. Molecular modelling studies also revealed that ARIP binds β-arrestins as does V2Rpp, the phosphorylated peptide derived from V2R, and that replacing the p-Ser and p-Thr residues of V2Rpp with Glu residues does not alter ARIP’s inhibitory activity on β-arrestin recruitment. Importantly, ARIP exerted an opioid-sparing effect <em>in vivo</em>, as intrathecal injection of ARIP potentiated morphine’s analgesic effect in the tail-flick test, consistent with previous findings of genetic inhibition of β-arrestins. ARIP therefore represents a promising pharmacological tool for investigating the fine-tuning roles of β-arrestins in 7TMR-driven pathophysiological processes.</div></div>","PeriodicalId":19918,"journal":{"name":"Pharmacological research","volume":"212 ","pages":"Article 107597"},"PeriodicalIF":9.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142971872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that the AMPK signalling pathway has a dual role in NSCLC progression, both inhibiting and promoting the progression of malignant tumours. Therefore, drugs targeting the AMPK signalling pathway may hold significant promise for therapeutic application in NSCLC. This review aims to examine the manifestations and mechanisms by which AMPK and its associated signalling molecules influence NSCLC progression and treatment. Firstly, we discuss the critical importance of AMPK within the mutational context of NSCLC. Secondly, we summarise the drugs and related substances that modulate the AMPK signalling pathway in NSCLC and evaluate the evidence from preclinical studies on combination AMPK-targeted therapies to address the issue of drug resistance in NSCLC under current clinical treatments.

This multicenter Phase II/III trial evaluated the optimal dosage, efficacy, and safety of SHR8554, a biased MOR agonist, for postoperative pain management following orthopedic surgery. In Phase II, 121 patients were divided into four groups to receive varying patient-controlled analgesia (PCA) doses of SHR8554 or morphine. Phase III involved 320 patients with similar groupings, including a placebo group. The primary outcome was the resting summed pain intensity difference over 24 hours (rSPID₂₄). Secondary outcomes included rSPID and active-SPID (aSPID) at other time points, rescue analgesia received, cumulative dose of analgesics, and satisfaction scores. Safety endpoints included treatment-emergent adverse events (TEAEs) and AE of special interest (AESIs). In both phases, SHR8554 demonstrated significant analgesic efficacy. In Phase II, the least squares (LS) mean differences in rSPID₂₄ compared to morphine for the 0.05 mg,0.1 mg, and 0.2 mg SHR8554 groups were 16.8 (p = 0.01), 7.4 (p = 0.27), and 0.2 (p = 0.98), respectively.

Trends in other secondary outcomes mirrored these findings. Safety analysis revealed that the 0.2 mg SHR8554 group had higher incidences of TEAEs (83.3 %) and AESIs (33.3 %) compared to other groups in Phase II. Similarly, in Phase III, the incidences of TEAEs were 81.0 %, 73.4 %, and 74.1 % in the 0.05 and 0.1 mg SHR8554 and morphine groups, respectively, compared with 61.3 % in the placebo group, while the AESIs were 29.1 %, 20.3 %, and 24.7 % compared with 12.5 % in the placebo group.
