Objective TXN is a thioredoxin (TXN) that participates in many redox reactions and plays a crucial role in various signaling pathways. However, the role of TXN in many cancers is still unclear. The objective of this study is to investigate and visualize the diagnostic, prognostic, and immunological implications of TXN expression across various cancer types. Methods The clinical data were downloaded from the cancer genome mapping project(TCGA) database to analyze the expression level of TXN in pan cancer, and the expression level was preliminarily verified by human protein mapping (HPA)(https://www.proteinatlas.org/)database. The ESTIMATE algorithm and CIBERSORT algorithm were applied to calculate the correlation between TXN expression and immune cell infiltration. The correlation between TXN and microsatellite instability (MSI) and tumor mutation burden (TMB) was analyzed using Spearman method. Gene Set Enrichment Analysis (GSEA) is used for gene biology functional analysis and sensitivity analysis of genes to pan cancer therapeutic drugs. Results TXN is highly expressed in most malignant tumors. The high expression of TXN is associated with overall survival (OS), disease-specific survival (DSS), disease-free interval (DFI), and progression free interval (PFI) in various cancers. Moreover, TXN expression is associated with TMB, MSI, tumor microenvironment, chemotherapy sensitivity and so on. Conclusion TXN may become a potential prognostic biomarker in pan cancer, providing strong theoretical basis for future tumor diagnosis and prognosis judgment. The retinoic acid-inducible gene-I (RIG-I)-like receptor signaling pathway, Toll-like receptor (TLR) signaling pathway, and nucleotide binding oligomerization domain (NOD)-like receptor signaling pathway may be crucial pathways through which TXN influences tumor immunity.

Background/Aims: To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets. Methods: We conducted Mendelian randomization (MR) to assess the causal role of circulating complements in the risk of non-viral liver diseases. A complement-centric protein interaction network was constructed to explore biological functions and identify potential therapeutic options. Results: In the MR analysis, genetically predicted levels of complement C1q C chain (C1QC) were positively associated with the risk of autoimmune hepatitis (odds ratio 1.125, 95% confidence interval 1.018–1.244), while complement factor H-related protein 5 (CFHR5) was positively associated with the risk of primary sclerosing cholangitis (PSC;1.193, 1.048– 1.357). On the other hand, CFHR1 (0.621, 0.497–0.776) and CFHR2 (0.824, 0.703–0.965) were inversely associated with the risk of alcohol-related cirrhosis. There were also significant inverse associations between C8 gamma chain (C8G) and PSC (0.832, 0.707–0.979), as well as the risk of metabolic dysfunction-associated steatotic liver disease (1.167, 1.036–1.314). Additionally, C1S (0.111, 0.018–0.672), C7 (1.631, 1.190–2.236), and CFHR2 (1.279, 1.059–1.546) were significantly associated with the risk of hepatocellular carcinoma. Proteins from the complement regulatory networks and various liver diseaserelated proteins share common biological processes. Furthermore, potential therapeutic drugs for various liver diseases were identified through drug repurposing based on the complement regulatory network. Conclusions Our study suggests that certain complement components, including C1S, C1QC, CFHR1, CFHR2, CFHR5, C7, and C8G, might play a role in non-viral liver diseases and could be potential targets for drug development.

Primary peritoneal carcinoma is rare, presents with non-specific abdominal symptoms, is usually diagnosed late and is associated with a poor prognosis. A 51-year-old female with Primary Peritoneal Carcinoma Stage III-C, was initially treated with cytoreductive surgery and intravenous paclitaxel and carboplatin. After 28 months in remission, she developed tumor recurrence. She underwent tumor excision followed by combined intravenous paclitaxel and intraperitoneal carboplatin. The patient is alive and disease-free 5 years after the initial operation. This case was reported to inform our clinicians that the peritoneum can be the primary site of a rare malignancy. Prognosis may be poor but long-term survival can be achieved in younger patients with good performance status. Having a tumor that is sensitive to platinum-based chemotherapy can contribute to a longer survival even if the tumor was sub-optimally reduced.

T-cell internal antigen-1 (TIA-1) has roles in regulating alternative pre-mRNA splicing, mRNA translation, and stress granule (SG) formation in human cells. As an evolutionarily conserved response to environmental stress, SGs have been reported in various species. However, SG formation in chicken cells and the role of chicken TIA-1 (cTIA-1) in SG assembly has not been elucidated. In the present study, we cloned cTIA-1 and showed that it facilitates the assembly of canonical SGs in both human and chicken cells. Overexpression of the chicken prion-related domain (cPRD) of cTIA-1 that bore an N-terminal green fluorescent protein (GFP) tag (pntGFP-cPRD) or Flag tag (pFlag-cPRD) induced the production of typical SGs. However, C-terminal GFP-tagged cPRD induced notably large cytoplasmic granules that were devoid of endogenous G3BP1 and remained stable when exposed to cycloheximide, indicating that these were not typical SGs, and that the pntGFP tag influences cPRD localization. Finally, endogenous cTIA-1 was recruited to SGs in chicken cells and tissues under environmental stress. Taken together, our study provide evidence that cTIA-1 has a role in canonical SG formation in chicken cells and tissues. Our results also indicate that cPRD is necessary for SG aggregation.

A 54-year old, single, nulligravid, without history of sexual contact, was admitted due to postmenopausal bleeding. Transrectal ultrasound revealed myoma uteri and thickened endometrium. She was thus scheduled to undergo endometrial curettage. However, prior to the performance of the endometrial sampling procedure, there was profuse vaginal bleeding with note of a possible prolapsed submucous myoma. She thus underwent emergency exploratory laparotomy with total hysterectomy and bilateral salpingooophorectomy.

Intraoperatively, necrotic masses were noted within the endocervical canal. Frozen section of the uterus and these masses revealed malignancy. Intraoperative referral to a gynecologic oncologist was done and bilateral pelvic lymphadenectomy and surgical staging were performed. Final histopathologic report revealed Cervical Adenosquamous Carcinoma. She subsequently underwent external beam radiotherapy and vaginal brachytherapy.

With the knowledge that almost all cases of cervical cancer is due to the Human Papilloma Virus (HPV), that this virus is almost exclusively transmitted by sexual contact, and the fact that she never engaged in sexual practices, there was doubt as to the source of the cancer. To help resolve this issue, an HPV DNA Polymerase Chain Reaction assay was performed on paraffin block samples and these all turned out negative for HPV. She may possess one of the rarest forms of cervical cancer - one that is not associated with the Human Papilloma Virus.
