Patients with lung adenocarcinomas (LUAD) frequently develop metastasis. In this issue of Cancer Cell, Lengel et al. perform a comprehensive analysis of metastasis patterns in 2,532 LUAD samples to identify clinicopathologic and genomic features of LUAD tumors associated with metastatic development, burden, and organotropism.

Introduction: The prevalence of germline pathogenic/likely pathogenic variants (P/LP) in high and moderate penetrance (HMP) genes is approximately 7%-10% among breast cancer (BC) patients. The prevalence and spectrum of BC P/LP variants are affected by several factors. There are limited genetic data from Brazilian patients with BC.

This report details the case of a preadolescent female patient diagnosed with Kabuki syndrome, a rare genetic disorder characterised by distinctive facial features, growth delay and cognitive impairment. The patient's medical history includes perinatal complications, alongside challenges in developmental milestones, feeding and psychomotor skills since infancy, prompting further investigation. Genetic testing confirmed the diagnosis, revealing a full deletion of The patient underwent a multidisciplinary approach, addressing various aspects of her condition, which resulted in significant improvements in several areas.

The tumor microenvironment, which is the tailored physiological milieu of heterogeneous cancer cell populations surrounded by stromal and immune cells as well as extracellular matrix components, is a leading modulator of critical cancer hallmarks and one of the most significant prognostic indicators in breast cancer. In the last few decades, with the discovery of the interactions of ncRNAs with diverse cellular molecules, considerable emphasis has been devoted to understanding their direct and indirect roles in specific functions in breast cancer. Collectively, all of these have revealed that the competitive action of protein-coding RNAs and ncRNAs such as circRNAs and lncRNAs, which have a shared affinity for miRNAs, play a vital role in the molecular regulation of breast cancer.

Homeostasis of cellular membranes is maintained by fine-tuning their lipid composition. Yeast lipid transporter Osh6, belonging to the oxysterol-binding protein-related proteins family, was found to participate in the transport of phosphatidylserine (PS). PS synthesized in the endoplasmic reticulum is delivered to the plasma membrane, where it is exchanged for phosphatidylinositol 4-phosphate (PI4P).

In aging, skeletal muscle regeneration declines due to alterations in both myogenic and non-myogenic cells and their interactions. This regenerative dysfunction is not understood comprehensively or with high spatiotemporal resolution. We collected an integrated atlas of 273,923 single-cell transcriptomes and high-resolution spatial transcriptomic maps from muscles of young, old and geriatric mice (~5, 20 and 26 months old) at multiple time points following myotoxin injury.
