Objective: The clinical significance of lymphocyte infiltration (LI) at the invasive front in endometrial carcinomas (EC) has not been determined. The aim of the current study was to evaluate the association between zone formation of LI at the invasive front of the tumor margin and prognoses of the patients with EC.
Methods: All available pathological slides of the enrolled cases were reviewed, and the degree of LI at the invasive front was categorized into 2 groups: strong LI and weak LI. Clinical significance of LI was evaluated retrospectively.
Results: A total of 333 cases with EC were enrolled in the study: 225 cases with weak LI and 108 cases with strong LI. Weak LI was more frequently observed in the patients with grade1/2 endometrioid EC. Multivariate analyses for progression-free survival (PFS) and overall survival (OS) revealed that weak LI was identified as an independent worse prognostic factor for OS (p = 0.004) in addition to PFS (p = 0.022).
Conclusion: Weak LI at the invasive front of the tumor margin was associated with worse prognoses in EC. Although further studies are needed, it is suggested that LI could be a biomarker of prognoses in EC.

Tumor initiation represents the first step in tumorigenesis during which normal progenitor cells undergo cell fate transition to cancer. Capturing this process as it occurs in vivo, however, remains elusive. Here we employ spatiotemporally controlled oncogene activation and tumor suppressor inhibition together with multiomics to unveil the processes underlying oral epithelial progenitor cell reprogramming into tumor initiating cells at single cell resolution.

Background: Bladder cancer (BC) is a common tumor worldwide. Screening for BC currently lacks a highly efficient, non-invasive, and inexpensive method. Serum microRNA (miRNA), which is stable and commonly present, has the potential to serve as a novel marker for BC diagnosis.

lncRNAs (long non-coding RNAs) are heterogeneous RNA molecules that modulate various cellular processes, such as proliferation, differentiation, migration, invasion, and apoptosis, via different mechanisms. An increasing amount of research indicates that abnormal expression of lncRNA influences the development of drug resistance as well as the genesis and advancement of cancer, including melanoma. Furthermore, they are attractive biomarkers for non-invasive cancer diagnostics due to their strongly modulated expression and improved tissue and disease specificity.

Background: Exonuclease 1 (EXO1), a protein involved in mismatch repair and recombination processes, has been identified as a prognostic biomarker in lung adenocarcinoma (LUAD). Nevertheless, its role in LUAD progression remains elusive. This study seeks to elucidate the functional significance of EXO1 in LUAD and evaluate its potential as a therapeutic target.

Background: In this study we investigate the selective compensation of paired peripheral nerves in healthy humans, focusing on distinct axonal conduction velocities in different fibre types. Using paired associative stimulation (PAS) with adjustable parameters, we aimed to modulate and compensate for neuronal activity along the median nerve.
Methods: Six healthy volunteers (3 male, 3 female, aged: 22-49) participated in the current study.
