FAM49B is upregulated in ovarian cancer tissues; however, its role and mechanism in ovarian cancer progression remain unknown. Herein, we demonstrated that FAM49B knockdown significantly increases ovarian cancer cell viability, EdU incorporation, and clonogenic growth. In contrast, the forced expression of FAM49B achieved opposite effects. Furthermore, an ovo model was used to assess the in vitro effects of FAM49B depletion or overexpression on the growth of ovarian cancer. In a xenograft model, we observed that FAM49B overexpression alleviated tumor formation. Transcriptomic analysis of FAM49B-depleted and control cells revealed that FAM49B silencing upregulated the MAPK pathway. Consistent with the transcriptomic analysis results, we noted that FAM49B knockdown enhanced EGFR activation and downstream MEK-ERK signaling; in contrast, FAM49B overexpression exhibited opposite trends. In addition, FAM49B played a role in EGF-induced sphere growth of ovarian cancer cells. Notably, treatment with the MEK inhibitor trametinib considerably impaired the increased cell growth by FAM49B knockdown in cell culture and ovo models. Collectively, our results suggest that FAM49B can suppress the growth of ovarian cancer cells by regulating the MAPK signaling pathway.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"15 9","pages":"4150-4164"},"PeriodicalIF":2.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12531276/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological and molecular evidence suggest a developmental link between abnormalities in germ cell development and testicular germ cell tumor (TGCT), but whether and how DAZ deficiency is associated with TGCT susceptibility remains unclear. Using a specific human embryonic stem cell (hESC) model, we constructed and characterized a DAZ-deleted cell line (SKLRMe001-A) and compared its efficiency of induction into human primordial germ cell-like cells (hPGCLCs) with that of the H1 control line. We assessed intersections between embryonic-like networks and HMGA1-P53-MAPK/PI3K pathways to explore the potential connection between DAZ deficiency and TGCT susceptibility. DAZ deficiency significantly reduced hPGCLC induction efficiency and downregulated early lineage markers such as SOX17, BLIMP1, and TFAP2C, accompanied by S-phase shortening, cell cycle dysregulation, and increased apoptosis. RNA sequencing and enrichment analyses indicated sustained upregulation of HMGA1 and pointed to dysregulated homeostasis of P53 stress responses and PI3K/AKT and MAPK signaling axes. These findings are consistent with features of TGCT, including maintenance of embryonic-like programs, activation of proliferative signals, and heightened DNA damage responses. Therefore, we propose that lineage differentiation defects and mismatches between stress and survival signaling caused by DAZ deficiency may produce in vivo a population of \"undifferentiated and susceptible\" cells that increase the risk of TGCT, while also explaining the developmental basis of male infertility. Using a human in vitro model, this study links DAZ deficiency to both infertility and TGCT susceptibility and identifies HMGA1 as a central transcriptional-signaling hub. This finding provides molecular clues for risk stratification and early surveillance in populations with DAZ deficiency and suggests that interventions targeting HMGA1 and the PI3K/AKT and MAPK pathways may simultaneously improve germline differentiation and reduce potential tumor risk.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"15 9","pages":"4067-4081"},"PeriodicalIF":2.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12531290/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, countermeasures to prevent 5-FU cardiotoxicity are lacking. Therefore, we tested the hypothesis that short-term, moderate-intensity exercise completed before 5-FU administration would prevent 5-FU-induced alterations in vascular and cardiac function. Male Sprague-Dawley rats were randomized to sedentary control (SEDCON, n = 9), sedentary 5-FU (SED5FU, n = 10), exercise control (EXCON, n = 8) or exercise 5-FU (EX5FU, n = 8) groups. Rats remained sedentary or completed 4-days of treadmill running (20-25 min, 20 m/min, 5% grade) with the final bout ending ~90-min before treatment with a clinically relevant dose of 5-FU (50 mg/kg bolus + 265 mg/kg 2-hr infusion) or volume matched saline. Echocardiographic indices of left ventricular function and Doppler measurements of aortic pulse wave velocity (PWV) were completed at baseline (BL) and after the 2-hr (2-hr) infusion. 5-FU did not induce changes in left ventricular function.
