Background: We previously described the enrichment of plasma exosome metabolites in CRPC, PCa, and TFC cohorts, and found significant differences in pyrimidine metabolites. The PMGs is associated with the clinical prognosis of several cancers, but its biological role in PCa is still unclear.
Methods: This study extracted 98 reliable PMGs, and analyzed their somatic mutations, expression levels, and prognostic significance.
Unlabelled: Quantitative understanding of mitochondrial heterogeneity is necessary for elucidating the precise role of these multifaceted organelles in tumor cell development. We demonstrate an early mechanistic role of mitochondria in initiating neoplasticity by performing quantitative analyses of structure-function of single mitochondrial components coupled with single cell transcriptomics. We demonstrate that the large Hyperfused-Mitochondrial-Networks (HMNs) of keratinocytes promptly get converted to the heterogenous Small-Mitochondrial-Networks (SMNs) as the stem cell enriching dose of the model carcinogen, TCDD, depolarizes mitochondria.

Introduction: Gestational trophoblastic disease (GTD) encompasses a constellation of rare to common gynecologic conditions stemming from aberrant gestations with distinct genetic backgrounds and variable degrees of trophoblast proliferation of either neoplastic or non-neoplastic nature. GTD is categorized into hydatidiform moles and gestational trophoblastic neoplasms, and their clinical outcomes vary widely across different subtypes. Prompt and accurate diagnosis plays a pivotal role in the effective management and prognostication of patients.

Mitophagy, the selective degradation of mitochondria by autophagy, plays a crucial role in cancer progression and therapy response. This study aims to elucidate the role of mitophagy-related genes (MRGs) in cutaneous melanoma (CM) through single-cell RNA sequencing (scRNA-seq) and machine learning approaches, ultimately developing a predictive model for patient prognosis. The scRNA-seq data, bulk transcriptomic data, and clinical data of CM were obtained from publicly available databases.
