Comparison among fertility-sparing therapies for well differentiated early-stage endometrial carcinoma and complex atypical hyperplasia

open access: yesOncoTarget, 2017
Objective To compare fertility-sparing therapies including oral progestogens, hysteroscopic resection (HR), and the levonorgestrel- releasing intrauterine system (LNG-IUS) in achieving disease regression, recurrence and live birth rate in well ...

Changes in mRNA expression of oncogenesis driver genes in atypical ductal breast hyperplasia

open access: yesОпухоли женской репродуктивной системы
Background. Atypical ductal hyperplasia is a relatively common breast lesion that increases the risk of breast cancer by 3.5 to 5 times. Genomic rearrangements underlying the development of atypical proliferative lesions and breast cancer lead to gene ...

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Diagnostic accuracy of hysteroscopy vs dilation and curettage (D&C) for atypical endometrial hyperplasia in patients performing hysterectomy or serial follow-up

open access: yesClinical and Experimental Obstetrics & Gynecology, 2022
Background: Endometrial hyperplasia (EH) is considered a heterogeneous pre-neoplastic clinical entity characterized by an abnormal glandular proliferation, with less than half of the tissue area occupied by the stroma. The aim of this retrospective study

Characterizing Stage‐Specific Cellular Dynamics and Microenvironmental Remodeling in Lung Adenocarcinoma by Single‐Cell RNA Sequencing

open access: yesAdvanced Science, EarlyView.
This study integrated early‐stage patient specimens with publicly available datasets encompassing non‐malignant lung tissues and advanced‐stage LUAD through single‐cell sequencing, revealing a dynamically remodeled tumor microenvironment characterized by a hypoxia‐adapted malignant subset (C5), immunosuppressive LGMN+ macrophages, STAT1‐driven ...

Ibuprofen Induces Reduction of the Proliferation-Seeking Radiotracer Tc-(V)DMSA Uptake in Severe Epithelial Breast Hyperplasia without Atypia

open access: yesMolecular Imaging, 2010
The purpose of this study was to investigate if ibuprofen intake can influence mammary uptake of the proliferation-seeking radiotracer technetium 99m–pentavalent dimercaptosuccinic acid ( 99m Tc-(V)DMSA) in women with severe epithelial and atypical ...

Spatial Profiling Reveals Distinct Molecular and Immune Evolution of Mouse Lung Adenocarcinoma Precancers with or Without Carcinogen Exposure

open access: yesAdvanced Science, EarlyView.
Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...

CD20+FCRL4+ B Cells Activate CD8+ T Cells via MHC‐I Restriction in Nasopharyngeal Carcinoma Anti‐Tumor Immunity

open access: yesAdvanced Science, EarlyView.
CD20⁺FCRL4⁺ B cells in nasopharyngeal carcinoma actively cross‐present exogenous tumor antigens via MHC‐I, enhancing CD8⁺ T‐cell activation, memory formation, and cytotoxicity. IFNγ‐driven WDFY4 upregulation facilitates this process. These findings reveal an unconventional B‐cell–mediated antitumor mechanism and indicate potential relevance to ...
