Purpose: The aim of this study was to estimate the diagnostic significance of carcinoembryonic antigen (CEA), beta(2)-microglobulin (beta(2)-MG), and calcitonin (CAL) as tumor markers in patients with lung cancer.
Patients And Methods: Sixty patients were included and CEA, beta(2)-MG, and CAL serum levels were measured before treatment, and one and 6 months after treatment.
Results: The results taken showed that CEA mean baseline level was 23.4 ng/ml (normal range 0-5 ng/ml and up to 8 ng/ml in smokers), elevated in 80% of small-cell lung cancer (SCLC) cases, in 93% of adenocarcinomas, in 84% of squamous-cell carcinomas, and in 84% of large-cell carcinomas. The mean beta(2)-MG level was 3.6 mg/l (normal range 0.7-3.4 mg/l), elevated in 70% of SCLC, in 40% of adenocarcinomas, in 66% of large-cell and in 50% of squamouscell carcinomas. The mean CAL level was 170 pg/ml (normal < 26 pg/ml), elevated in 60% of SCLC, in 33% of adenocarcinomas, in 16% of large-cell and in 16% of squamouscell carcinomas.
Conclusion: CEA, beta(2)-MG, and CAL can be used as tumor markers with diagnostic value in primary lung cancer.

Both DNA replication and RNA transcription utilize genomic DNA as their template, necessitating spatial and temporal separation of these processes. Conflicts between the replication and transcription machinery, termed transcription-replication conflicts (TRCs), pose a considerable risk to genome stability, a critical factor in cancer development. While several factors regulating these collisions have been identified, pinpointing primary causes remains difficult due to limited tools for direct visualization and clear interpretation.

Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of the p16-pRb pathway by constitutive expression of mutant cyclin-dependent kinase 4 (R24C) (CDK4) and cyclin D1, and ii) acquisition of telomerase reverse transcriptase (TERT) activity, we established a human ovarian endometrioid carcinoma cell line from a 46-year-old Japanese woman. That line, designated JFE-21, has proliferated continuously for over 6 months with a doubling time of ~ 55 h.

Purpose: Urinary cytokine changes may serve as biomarkers to assess treatment outcomes for interstitial cystitis/bladder pain syndrome (IC/BPS). This study analyzed the changes in urinary cytokines following various bladder therapies and explored their clinical significance in therapeutic mechanisms.
Methods: A total of 122 patients with IC/BPS treated with platelet-rich plasma (PRP), botulinum toxin-A (BoTN-A), hyaluronic acid (HA), or low-energy shock wave (LESW) were evaluated.

Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.
Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.

Purpose: Growing evidence suggests that the tyrosine phosphatase SHP2 is pivotal for tumor progression. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer, characterized by its high recurrence rate, aggressive metastasis, and resistance to chemotherapy. Understanding the mechanisms of tumorigenesis and the underlying molecular pathways in TNBC could aid in identifying new therapeutic targets.
