Microtubules are dynamic polymers composed of α- and β-tubulin heterodimers. Microtubules are universally conserved among eukaryotes and participate in nearly every cellular process, including intracellular trafficking, replication, polarity, cytoskeletal shape, and motility. Due to their fundamental role in mitosis, they represent a classic target of anti-cancer therapy. Microtubule-stabilizing agents currently constitute a component of the most effective regimens for ovarian cancer therapy in both primary and recurrent settings. Unfortunately, the development of resistance continues to present a therapeutic challenge. An understanding of the underlying mechanisms of resistance to microtubule-active agents may facilitate the development of novel and improved approaches to this disease.

Objective: Endometrial cancer (EC) and epithelial ovarian cancer (EOC) affect women of all ages, and the incidence of endometrial cancer in premenopausal women is rising. Menopause can be detrimental to longevity and quality of life, but evidence suggests estrogen therapy (ET) is safe in these patients. The purpose of this study was to evaluate the practice patterns of gynecologists and gynecologic oncologists (GYO) in the United States in regards to prescription of ET to gynecologic cancer patients.

MicroRNAs (miRNAs) are critical regulators of gene expression in cancer biology, yet their spatial dynamics within tumor microenvironments (TMEs) remain underexplored due to technical limitations in current spatial transcriptomics (ST) technologies. To address this gap, we present STmiR, a novel XGBoost-based framework for spatially resolved miRNA activity prediction. STmiR integrates bulk RNA-seq data (TCGA and CCLE) with spatial transcriptomics profiles to model nonlinear miRNA-mRNA interactions, achieving high predictive accuracy (Spearman's ρ > 0.

Antibody-drug conjugates (ADCs) represent a promising therapeutic approach in gynecologic cancers, particularly ovarian and cervical malignancies. Agents such as mirvetuximab soravtansine, and tisotumab vedotin, targeting folate receptor alpha and tissue factor, respectively, reported clinical efficacy in patients with limited options. However, their use is associated with ocular toxicities, including keratopathy, blurred vision, and dry eye, which may impact adherence and quality of life.

Tumor-associated macrophages (TAMs) act as a vital player in the immunosuppressive tumor microenvironment (TME) and have received widespread attention in the treatment of cancer in recent times. Nevertheless, simultaneously inducing TAM repolarization and strengthening their phagocytic ability on cancer cells is still a significant challenge. Ferroptosis has received widespread attention due to its lethal effects on tumor cells, but its role in TAMs and its impact on tumor progression have not yet been defined.

Ovarian cancer remains a major health threat with limited treatment options available. It is characterized by immunosuppressive tumor microenvironment (TME) maintained by tumor-associated macrophages (TAMs) hindering anti-tumor responses and immunotherapy efficacy. Here we show that targeting retinoblastoma protein (Rb) by disruption of its LxCxE cleft pocket causes preferential cell death in Rbhigh M2 polarized or M2-like Rbhigh immunosuppressive TAMs by induction of ER stress, p53 and mitochondria-related cell death pathways.
