Biochemical recurrence (BCR) of prostate cancer (PCa) negatively impacts patients' post-surgery quality of life, and the traditional predictive models have shown limited accuracy. This study develops an AI-based prognostic model using deep learning that incorporates androgen receptor (AR) regional features from whole-slide images (WSIs). Data from 545 patients across two centres are used for training and validation. The model showed strong performances, with high accuracy in identifying regions with high AR expression and BCR prediction. This AI model may help identify high-risk patients, aiding in better treatment strategies, particularly in underdeveloped areas.

The objective of this research was to use a network toxicology approach to examine the possible toxicity of the cigarette toxicants nicotine and coal tar that cause osteoporosis (OP) as well as its molecular processes. We determined the primary chemical structures and 128 targets of action of tar and nicotine using the Swiss Target Prediction, NP-MRD, and PubChem databases. We discovered that genes including DNAJB1, CCDC8, LINC00888, ATP6V1G1, MPV17L2, PPCS, and TACC1 had a disease prognostic guiding value by LASSO analysis and differential analysis of GEO microarray data.

Human Kallikrein 2 (KLK2) is a prostate cancer tissue specific protein that is regulated by androgen receptor (AR) signaling. KLK2 was not previously recognized as a therapeutic target as it is secreted. It has now been demonstrated that KLK2 is expressed on the cell surface and targetable by various methodologies.

The presence of androgen receptor (AR) as a marker can be detected in all breast cancer subtypes, and it may provide information on treatment response and prognosis. This study aimed to examine the correlation between AR expression and treatment response in patients diagnosed with human epidermal growth factor receptor 2 (HER2) positive breast cancer who were undergoing neoadjuvant therapy (NAT). The evaluation included breast cancer patients who received NAT and underwent surgery at Weifang People's Hospital's Department of Breast Surgery between October 2019 and October 2022.

Dysfunction of several WD40 family proteins causes diverse endocrine diseases. Until recently, MEP50, a WD40 protein, was considered a Gene of Unknown Significance (GUS) because no inherited diseases had been linked to its function. However, genetic inactivation of MEP50 in mouse models or somatic mutations in humans drive oncogenesis in several endocrine-related cancers, including those of the prostate, breast, and uterus.

Background: This study aimed to reclassify a subset of poorly differentiated salivary gland carcinoma that do not conform to any entities of the current World Health Organization (WHO) classification into the category of undifferentiated carcinoma (UDC) because they lack specific histologic differentiation or immunophenotype.
Methods: Cases of salivary gland carcinomas from Asan Medical Center (2002-2020) that did not fit any existing WHO classification criteria and were diagnosed as poorly differentiated carcinoma, high-grade carcinoma, or UDC, were retrospectively reviewed. Immunohistochemical (IHC) staining for p40, neuroendocrine markers, androgen receptor (AR), and gross cystic disease fluid protein 15 (GCDFP-15) and Epstein-Barr virus (EBV) in situ hybridization (ISH) were performed.
