Tumor-stroma ratio in preoperative biopsies and matched surgical specimens in oral squamous cell carcinoma: Concordance and impact on recurrence-free and overall survival
Pathol Res Pract. 2024 Feb 16;255:155211. doi: 10.1016/j.prp.2024.155211. Online ahead of print.ABSTRACTStroma-richness is commonly associated with decreased survival times as well as advanced tumor stages in various malignant tumors. A previous study on laryngeal squamous cell carcinomas showed very good agreement for tumor-stroma ratio assessment between pre-treatment biopsies and resection specimens. We therefore aimed to determine whether similar results could be shown for oral squamous cell carcinomas. 107 preoperative biopsies and matched surgical specimens were obtained from the histological archive, dating from 201...

Transcription factor RELA promotes hepatocellular carcinoma progression by promoting the transcription of m6A modulator METTL3
CONCLUSION: RELA promotes the transcription of METTL3 by binding to METTL3 promoter region, thus promoting the malignancy of HCC cells. This study suggests NF-κB signaling contributes the dysregulation of m6A modification in HCC tumorigenesis.PMID:38367599 | DOI:10.1016/j.prp.2024.155168 (Source: Pathology, Research and Practice)

TIGIT: A potential immunotherapy target for gynecological cancers
Pathol Res Pract. 2024 Feb 7;255:155202. doi: 10.1016/j.prp.2024.155202. Online ahead of print.ABSTRACTGynecological cancer represents a significant global health challenge, and conventional treatment modalities have demonstrated limited efficacy. However, recent investigations into immune checkpoint pathways have unveiled promising opportunities for enhancing the prognosis of patients with cancer. Among these pathways, TIGIT has surfaced as a compelling candidate owing to its capacity to augment the immune function of NK and T cells through blockade, thereby yielding improved anti-tumor effects and prolonged patient survi...

Hepatic granulomas following liver transplantation: A retrospective survey, and analysis of possible microbiological etiology
CONCLUSION: Our study confirmed that granulomas are frequently seen in liver allograft biopsy specimens, and most often localized in the parenchyma, occurring in the first post-transplant period in patients with AILD, and often seen simultaneously with episodes of ACR. Neither a specific microbiological etiological agent nor a consistent microbiome was detected in any case.PMID:38367601 | DOI:10.1016/j.prp.2024.155201 (Source: Pathology, Research and Practice)

The hidden threat: Environmental toxins and their effects on gut microbiota
Pathol Res Pract. 2024 Jan 28;255:155173. doi: 10.1016/j.prp.2024.155173. Online ahead of print.ABSTRACTThe human gut microbiota (GM), which consists of a complex and diverse ecosystem of bacteria, plays a vital role in overall wellness. However, the delicate balance of this intricate system is being compromised by the widespread presence of environmental toxins. The intricate connection between contaminants in the environment and human well-being has garnered significant attention in recent times. Although many environmental pollutants and their toxicity have been identified and studied in laboratory settings and animal m...

Immunohistochemical and molecular pattern of p53 in epithelial ovarian cancers negative for germline BRCA1/2 variants
We describe TP53 mutation results in relationship to the immunohistochemical pattern of p53 expression in a series of EOCs negative for BRCA1 and BRCA2 germline mutations. In addition, we also investigated STIC presence and "p53 signature" in fallopian tube sampling of these EOCs. Our results demonstrate that TP53 alterations are frequent and early events in sporadic EOCs including also low-grade carcinomas. Also in this series, STIC is associated with an abnormal p53 pattern in fallopian tubes of high-grade EOCs. In summary, TP53 aberrations are the most frequent and early molecular events in EOC carcinogenesis independen...

Online ahead of print.ABSTRACTIL-33 is a multifaceted cytokine, plays a pivotal role in various biological processes, making it a subject of extensive research and intrigue in the field of immunology. This cytokine acts as a key regulator, effectively putting the brakes on proinflammatory nuclear factor-kappa B (NF-κB), thereby modulating chromatin compaction by promoting nucleosome-to-nucleosome interactions. IL-33's influence extends to the realm of innate and acquired immunity through its binding to the membrane-bound ST2 molecule (ST2L) of the I...
