This study aimed to evaluate the correlation between hematoxylin and eosin-based histological immunophenotypes and gene signatures employed in several clinical trials predicting responsiveness to immune checkpoint inhibitors and tyrosine kinase inhibitors, using data from the Cancer Genome Atlas (TCGA)-KIRP cohort (n = 254). Herein, we evaluated tumor-associated immune cells (TAICs) using three methodologies previously reported in clear cell RCC: a 3-tier immunophenotype (desert, excluded, and inflamed) based on the spatial distribution of TAICs; a 4-tier immunophenotype (cold, immune-low, excluded, and hot) considering both the location and degree of TAICs; and an inflammation score (score 0, 1, and 2) focusing only on the degree of TAICs. Furthermore, we compared the predictive ability of the three immunophenotypes. The histological immunophenotype in pRCC exhibited a correlation with adverse clinicopathological factors (including higher stage, WHO/ISUP grade, and the presence of sarcomatoid/rhabdoid changes), gene signatures related to angiogenesis, Teff, myeloid cells, JAVELIN Renal 101 Immuno, and immune checkpoints, as well as a poorer prognosis. Among the three methodologies, the 4-tier immunophenotype demonstrated the strongest correlation with gene signatures. In conclusion, the 4-tier immunophenotype may yield potential predictive biomarkers for pRCC and guide treatment decisions.</div></div>","PeriodicalId":19916,"journal":{"name":"Pathology, research and practice","volume":"266 ","pages":"Article 155764"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142846710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For better clinical diagnosis and treatment, it is important to understand the molecular mechanisms of tumor formation. In this study, the expression of the CacyBP/SIP protein and ERK1/2 and p38 kinases was analyzed for the first time in seminomas and normal testicular tissues. The research was carried out using archival tissue material from 30 patients undergoing surgery due to testicular seminoma, whereas the comparative material consisted of the adjacent normal tissues. Immunohistochemistry and qRT-PCR were used to identify the expression of CacyBP/SIP, ERK1/2, and p38. A marked weakening of the immunohistochemical reaction was observed in the cancerous tissue compared to the control tissue. PCR testing of the marked proteins confirmed their lower expression in seminoma. Our findings suggest the involvement of the CacyBP/SIP protein in the ERK1/2 and p38 signalling pathways, which may be involved in the processes of testicular seminoma carcinogenesis.

LncRNAs are non-coding RNAs that have more than 200 nucleotides that play a crucial role in gene regulation at the post-translational stage, transcriptional, and epigenetic levels. LncRNA MALAT1 regulates gene expression and modulates cellular functions such as proliferation, inflammation, apoptosis, and fibrosis, which are key pathophysiology of kidney diseases. Overexpression of lncRNA MALAT1 has been consistently observed in kidney tissue, correlating with the severity and progression of kidney disease. In AKI, lncRNA MALAT1 exacerbates inflammation and tissue damage, contributing to disease progression. In CKD and DKD, lncRNA MALAT1 is implicated in the regulation of fibrosis by modulating key pathways, including focal adhesion kinase (FAK), toll-like receptor 4 (TLR4), NOD-like receptor protein3 (NLRP3), and nuclear factor kappa B (NF-κB), play pivotal roles in promoting disease progression. In LN, lncRNA MALAT1 has been linked to immune regulation and kidney damage, while in RCC, its role in promoting tumor growth and metastasis has been well documented. Preclinical research has demonstrated that therapeutic strategies targeting lncRNA MALAT1, such as knockdown and knockout, can reduce inflammation and fibrosis while improving kidney function. The fundamental role of lncRNA MALAT1 in kidney disease progression is yet to be fully understood.
