Current state and future prospects of spatial biology in colorectal cancer.

Over the past century, colorectal cancer (CRC) has become one of the most devastating cancers impacting the human population. To gain a deeper understanding of the molecular mechanisms driving this solid tumor, researchers have increasingly turned their attention to the tumor microenvironment (TME). Spatial transcriptomics and proteomics have emerged as a particularly powerful technology for deciphering the complexity of CRC tumors, given that the TME and its spatial organization are critical determinants of disease progression and treatment response.

WNT and TGF-Beta Pathway Alterations in Early-Onset Colorectal Cancer Among Hispanic/Latino Populations.

Background/objectives: One of the fastest-growing minority groups in the U.S. is the Hispanic/Latino population.

Integrative multi-omics profiling of colorectal cancer from a Hispanic/Latino cohort of patients.

Colorectal cancer contributes to cancer-related deaths and health disparities in the Hispanic and Latino community. To probe both the biological and genetic bases of the disparities, we characterized features of colorectal cancer in terms of somatic alterations and genetic similarity. Specifically, we conducted a comprehensive genome-scale analysis of 67 Hispanic and Latino samples.

Senescent glia link mitochondrial dysfunction and lipid accumulation.

Senescence is a cellular state linked to ageing and age-onset disease across many mammalian species. Acutely, senescent cells promote wound healing and prevent tumour formation; but they are also pro-inflammatory, thus chronically exacerbate tissue decline. Whereas senescent cells are active targets for anti-ageing therapy, why these cells form in vivo, how they affect tissue ageing and the effect of their elimination remain unclear.
