Irradiation-induced brain injury was studied in C57BL/6 mice via DNA damage response, using nuclear γH2AX as a marker for double-strand breaks.

Additionally, FLASH RT reduced neuroinflammatory signals compared with SDR, as indicated by fewer CD68+ inducible nitric oxide synthetase-positive microglia/macrophages.

In this study, we present a comprehensive characterization of TNG348, an allosteric, selective, and reversible inhibitor of USP1. TNG348 induces dose-dependent accumulation of ubiquitinated protein substrates both in vitro and in vivo. CRISPR screens show that TNG348 exerts its antitumor effect by disrupting the translesion synthesis pathway of DNA damage tolerance through RAD18-dependent ubiquitinated PCNA. Although TNG348 and PARPi share the ability to selectively kill HRD tumor cells, CRISPR screens reveal that TNG348 and PARPi do so through discrete mechanisms. Particularly, knocking out PARP1 causes resistance to PARPi but sensitizes cells to TNG348 treatment. Consistent with these findings, combination of TNG348 with PARPi leads to synergistic antitumor effects in HRD tumors, resulting in tumor growth inhibition and regression in multiple mouse xenograft tumor models. Importantly, our data on human cancer models further show that the addition of TNG348 to PARPi treatment can overcome acquired PARPi resistance in vivo. Although the clinical development of TNG348 has been discontinued because of unexpected liver toxicity in patients (NCT06065059), the present data provide preclinical and mechanistic support for the continued exploration of USP1 as a drug target for the treatment of patients with BRCA1/2-mutant or HRD cancers.</p>","PeriodicalId":18791,"journal":{"name":"Molecular Cancer Therapeutics","volume":" ","pages":"678-691"},"PeriodicalIF":5.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12046316/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066696","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}

High-dose testosterone (Hi-T) has recently emerged as a promising treatment for CRPC, primarily through the suppression of E2F and MYC signaling.

In this study, we utilized a CRPC patient-derived xenograft model that includes both Rb pathway-proficient and -deficient cell populations based on the positive or negative expression of RB family genes. Single-cell RNA sequencing analysis revealed that Rb-proficient cells displayed a robust response to Hi-T, whereas Rb-deficient cells exhibited significant resistance.

CD3 redirection antibodies in solid tumors are still in the early phases of clinical development, and it is not yet understood whether these potential therapies will achieve the high response rates observed in hematologic malignancies or result in durable T-cell responses. In this study, we demonstrated that treatment with a prostate-specific membrane antigen (PSMA)-targeted CD3 redirector resulted in efficacy against LnCaP.AR human prostate xenografts in CD34+ cord blood-humanized mice. Efficacy correlated with T-cell infiltration into tumors with an activated phenotype and also increased PD-L1 expression.

This study aimed to develop a bispecific antibody (BsAb) to co-target TIGIT and PVRIG. Expression of TIGIT and PVRIG was assessed on tumor-infiltrating lymphocytes from patients with various cancers, including non-small cell lung cancer (n = 63) and colorectal cancer (n = 26). The BsAb was engineered by fusing anti-PVRIG nanobodies to the N terminus of anti-TIGIT antibodies. Functional characterization of the BsAb was performed in vitro and in vivo, including assessments of T- and NK-cell activation and cytotoxicity. Pharmacokinetics and safety profiles were evaluated in cynomolgus monkeys. Statistical analyses were conducted using the Student t test. The results showed that the BsAb effectively blocked TIGIT and PVRIG from binding their respective ligands, CD155 and CD112, leading to significant increases in T-cell activation (2.8-fold; P < 0.05) and NK-cell cytotoxicity (1.8-fold; P < 0.05). In vivo, the BsAb demonstrated potent antitumor activity, both as a monotherapy and in combination with anti-PD-1 or anti-PD-L1, in humanized peripheral blood mononuclear cell-reconstituted and transgenic mouse models.
