Objective: Analyzing the protein expression of biomarkers CK7, Vim, and P53 to investigate their possible pathogenic roles in the development of variant subtypes of endometrial carcinoma.
Methods: Biomarkers CK7, Vim, and P53 were immunohistochemistry-stained among 131 endometrial carcinoma specimens including 93 endometroid, 8 adenoacanthoma, and 32 rare subtypes of adenosquamas carcinoma, clean cell carcinoma, and papillary carcinoma, which had been confirmed clinically and pathologically, and studied statistically with Fisher test and Cochran-Mantel-Haenszel (CMH) Test.
Results: Positive correlation was demonstrated among CK7, Vim, and P53 expression levels. The CK7 protein expression is increased, while the Vim and P53 are decreased in the subtype of endometrioid carcinoma. The clinical staging of endometriroid carcinoma is positively correlated with the expression of Vim. The positive rate of Vim and P53 is correlated with cytological differentiation of the carcinoma cells.
Conclusion: Biomarkers CK7, Vim, and P53 are playing pathogenic roles, assuming as a mutual transcriptional modulator, and Vim but not P53 is likely the favorable prognostic factor, in the development of variant subtypes of endometrial carcinoma in addition to a evaluating the treatment.

Case report: Carcinosarcoma of uterus in nulliparous women.

Article Synopsis
- Uterine carcinosarcoma (UCS) is a rare cancer combining both carcinoma and sarcoma features, often resembling endometrial carcinoma, with a potential link to nulliparity (never having given birth) as a risk factor.
- A 55-year-old woman presented with postmenopausal vaginal bleeding and was diagnosed after surgery, revealing well-differentiated adenocarcinoma and osteosarcoma components, along with multiple positive immunohistochemical markers.
- Following a series of surgical interventions and treatments, including chemotherapy and radiotherapy, the patient demonstrated no signs of tumor recurrence and had a disease-free survival of seven months as of July 2024.
p53 and Vimentin Double Immunostaining to Differentiate between High-Grade Urothelial Carcinoma Cells and Benign Atypical Cells.
Acta Cytol

Department of Medical Biophysics, Kobe University Graduate School of Health Sciences, Kobe, Japan.
Introduction: Urine cytology is an indispensable test for detecting high-grade urothelial carcinoma (HGUC); however, the distinction between HGUC cells and morphologically similar benign atypical cells poses clinical challenges. In this study, we performed double immunostaining for p53 and vimentin to establish a diagnostic method to accurately distinguish HGUC cells from benign atypical cells.
Methods: This study included 41 cases of HGUC, 11 of urolithiasis, and 22 of glomerular disease diagnosed histopathologically or clinically.
GTP Cyclohydrolase Drives Breast Cancer Development and Promotes EMT in an Enzyme-Independent Manner.

Unlabelled: GTP cyclohydrolase (GCH1) is the rate-limiting enzyme for tetrahydrobiopterin (BH4) biosynthesis. The catalysis of BH4 biosynthesis is tightly regulated for physiological neurotransmission, inflammation, and vascular tone. Paradoxically, BH4 has emerged as an oncometabolite regulating tumor growth, but the effects on tumor development remain controversial.

Understanding the molecular mechanism(s) of small compounds in cellular growth control are essential for using those against the disease(s). Oral cancers exhibit a very high mortality rate due to higher metastatic potential. Aberrant EGFR, RAR, HH signalling, enhanced [Ca] and oxidative stress are some of the important characteristics of oral cancer.
