Objective: This study was designed to evaluate the immunohistochemical expression of proliferating cell nuclear antigen (PCNA) and p53 protein expression in preneoplastic and neoplastic lesions in uterine cervix.
Study Design: A total of 36 cervical biopsies were subjected for immunostaining and the results were correlated with different prognostic parameters. Bivariate and multivariate statistical analyses were done using "STATA" software.
Results: PCNA labeling index and p53 expression increased with increasing severity of CIN lesions. PCNA labeling index was maximum (46.0) carcinoma cervix with intense positive staining. In bivariate statistical analysis, p53 and PCNALI were found to be insignificant (0.4184 and 0.4328, respectively). Menopausal stage was significantly associated with CA and CIN groups (P < 0.166 and P < 0.049), respectively.
Conclusion: These markers may be of greater importance in low-grade CIN lesions showing high proliferative index. This will place the low-grade lesions in higher grade indicating the utility of proliferative markers in decision making for intervention. This method is simple and cost effective and may be useful in developing countries where HPVDNA testing is still out of reach because of high cost.

Lysine lactylation plays critical roles in various diseases, including cancer. Our previous study showed that lactylation of non-histone ABCF1 may be involved in hepatocellular carcinoma (HCC) progression. In this study, we evaluated the prognostic value of ABCF1-K430la in HCC using immunohistochemical staining and performed amino acid point mutations, multi-omics crossover, and biochemical experiments to investigate its biological role and underlying mechanism.

Background: AT-rich interaction domain 4B (ARID4B) is a transcriptional activator that regulates the phosphatidylinositol 3-kinase (PI3K)/AKT pathway in prostate cancer. However, the role of ARID4B in hepatocellular carcinoma (HCC) has remained unclear.
Methods: This study included 162 patients who had undergone primary hepatic resection for HCC between 2008 and 2019.

In our previous phase II T1219 trial for advanced biliary tract cancer (ABTC), the combination of nivolumab with modified gemcitabine and S-1 exhibited promising efficacy, while the programmed-death-ligand-1 (PD-L1) expression did not predict chemoimmunotherapy efficacy. Lymphocyte-activation-gene-3 (LAG-3), a negative immune checkpoint, is frequently co-expressed with PD-L1. This study assessed the predictive value of LAG-3 expression in ABTC patients who received chemoimmunotherapy.

Objectives: We focused on how the immunophenotypes based on the distribution of CD8-positive tumor-infiltrating lymphocytes (TILs) relate to the endometrial cancer (EC) molecular subtypes and patients' prognosis.
Patients And Methods: Two cohorts of EC patients (total n = 145) were analyzed and categorized using the Molecular Risk Classifier for Endometrial cancer (ProMisE): POLEmut (POLE mutation), MMRd (mismatch repair deficiency), NSMP (no specific molecular profile), and p53abn (p53 abnormality). CD8-positive TILs, within the central tumor and the invasive margin, were examined by using immunohistochemical staining and advanced image-analysis software.

Background: Sporadic Alzheimer's Disease (sAD) is the most prevalent progressive neurodegenerative disease worldwide, without a cure. We propose to investigate therapies that contribute to the current state of this problem using a model of sAD in rats based on a single intracerebroventricular (icv) injection of streptozotocin (STZ). In this sense, thymulin (originally known as serum thymic factor, FTS), a thymic peptide, emerges as a potential therapeutic agent due to its proven anti-inflammatory effects.
