Our aim is to investigate the relationship between the expression of MRPS5 in clear cell renal cell carcinoma (ccRCC) and the prognosis of patients. MRPS5 expression in fresh tumoral tissues and peritumoral tissues of patients with ccRCC was examined by quantitative reverse transcription polymerase chain reaction, western blotting, and immunohistochemical staining, respectively. MRPS5 expression level in paraffin-embedded tumoral tissue samples with ccRCC was evaluated by immunohistochemical scoring criteria. The relationship between the expression of MRPS5 and the clinicopathological parameters and prognosis of patients with ccRCC was analyzed statistically. The expression of MRPS5 mRNA and protein in fresh tumoral tissues was lower than that in peritumoral tissues. Among 160 paraffin-embedded tumoral tissue samples, 99 cases (61.9%) showed high expression and 61 cases (38.1%) showed low expression of MRPS5. The expression level of MRPS5 was significantly correlated with T classification, TNM stage, and Fuhrman grade. Kaplan-Meier method and log-rank test indicated that patients with low MRPS5 expression had significantly poorer overall survival and recurrence-free survival than high MRPS5 expression. Multivariate analysis revealed that MRPS5 expression was an independent predictor of overall survival and recurrence-free survival, respectively. MRPS5 low expression was a risk factor for the prognosis of patients. The expression level of MRPS5 is significantly correlated with the postoperative survival status, which has the potential to be used as a novel prognostic biomarker for patients with ccRCC.</p>","PeriodicalId":48952,"journal":{"name":"Applied Immunohistochemistry & Molecular Morphology","volume":"33 1","pages":"22-28"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11614452/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite a clinical benefit rate of 80%, the majority of patients with GIST experience disease progression after 2 to 3 years of imatinib therapy. This shows the need for novel treatment approaches for imatinib refractory GISTs. The checkpoint proteins B7-H3 and B7-H4 inhibit the activation and function of T cells by potently suppressing the proliferation, cytokine production, and cytotoxicity of activated T cells, which is a mechanism for immune escape. This study aims to clarify B7-H3 and B7-H4 expression in gastric GISTs using immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). We confirmed B7-H3 expression (H-score ≥50 points) in 92% and B7-H4 expression in 0% of GIST samples. We examined B7-H3 mRNA expression in 3 representative GIST samples, each having their respective immunostained areas detected by RT-PCR. B7-H3 is expressed at a particularly high rate in GISTs.

The Cell DIVE mIF platform (Leica Microsystems) employs an alkaline solution of hydrogen peroxide as a fluorophore inactivation reagent in the sequential staining, imaging, and bleaching protocol for use on FFPE sections. Suboptimal bleaching efficiency, degradation of tissue structure, and loss of antigen immunogenicity occasionally are encountered with the standard bleaching process. To overcome these impediments, we adopted a modified photochemical bleaching method, which utilizes an intense LED light exposure concurrent with the application of hydrogen peroxide. Repeated stain/bleach rounds with different antibodies were performed on breast tissue and other tissue sections. Residual signal after conventional bleaching and the modified technique were compared and tissue integrity and antigen immunogenicity were assessed. The modified technique effectively eliminates fluorescence signal from previous staining rounds and produces consistent results for multiple rounds of staining and imaging. With the modified method, photochemical treatments did not destroy tissue sub-cellular contents, and the tissue antigenicity was well preserved during the entire mIF process. Overall processing time was reduced from 36 to 30 hours in an mIF procedure with 8 rounds. With the conventional method, tissue quality was highly degraded after 8 rounds.

Blood samples from 65 confirmed cases of TNBC were collected. DNA was isolated from whole blood and libraries were prepared using a BRCA1/2 custom panel. Sequencing was done on Ion torrent S5 sequencer and ion reporter was used for data analysis.

Twenty five of 65 patients had heterozygous pathogenic mutations, alterations with conflicting interpretation of pathogenicity, variants of uncertain significance and variants of unknown significance. Nine patients had pathogenic mutation in BRCA 1 gene only and 2 patients had pathogenic mutations in BRCA2 gene. Two patients were transheterozygous for BRCA mutations, that is, had pathogenic mutations in both BRCA1/2 genes simultaneously and 5 were compound heterozygous (involving BRCA2 gene in all the cases).

It protects the skin from damage by ultraviolet radiation. Although this pigment plays a crucial role in protecting the human body, it represents a challenge for pathologists to evaluate highly pigmented tissue samples from melanoma or pigmented skin lesions. Abundant melanin may obscure tissue morphology, which makes it very difficult for pathologists to make a differential diagnosis. Melanin pigment is brown-to-black and granular, and its distribution is often uneven in tissues. The presence of these pigments can complicate the analysis of immunohistochemistry (IHC) for 2 reasons. First, they have a direct physical masking effect on antigen-antibody interactions. Second, 3,3-diaminobenzidine, the most commonly used chromogen, has a brown color that is difficult to distinguish from melanin pigment. Therefore, melanin bleaching has become a crucial step in handling pigmented melanocytic lesions. Bleaching techniques aid pathologists in histopathologic examination of melanin-rich tissue. In this study, we integrated melanin bleaching and IHC on an automated IHC platform to set up a rapid and fully automated procedure. Bleaching steps were performed before antigen retrieval. Samples were treated with 1% hydrogen peroxide solution in Tris-HCl buffer (pH 10) at 80°C for 8 minutes, achieving optimal conditions for melanin bleaching while preserving tissue morphology and antigenicity.
