NMR and MS reveal characteristic metabolome atlas and optimize esophageal squamous cell carcinoma early detection
Lijing Xin, Yubo Zhao, Yan Lin, Wei Ye
Metabolic changes precede malignant histology. However, it remains unclear whether detectable characteristic metabolome exists in esophageal squamous cell carcinoma (ESCC) tissues and biofluids for early diagnosis. Here, we conduct NMR- and MS-based metabo ...
Nature Portfolio2024Transposable elements mediate genetic effects altering the expression of nearby genes in colorectal cancer
Didier Trono, Evaristo Jose Planet Letschert, Nikolaos Lykoskoufis
Transposable elements (TEs) are prevalent repeats in the human genome, play a significant role in the regulome, and their disruption can contribute to tumorigenesis. However, TE influence on gene expression in cancer remains unclear. Here, we analyze 275 n ...
2024Mechanism of KRAS-driven T cell infiltration in colorectal cancer
Colorectal cancer is the second-leading cause of cancer death worldwide. Early-stage disease can be detected with preventative medical screening and is treatable with surgical resection. Sixty-percent of patients, however, are diagnosed with advanced-stage ...
EPFL2023Regulation and function of a hemicleaved Activin-A processing intermediate in melanoma
Activin-A is a Transforming Growth Factor-B (TGFB)-related cytokine that regulates various biological processes including cell proliferation and differentiation through autocrine, paracrine or endocrine signaling. Activin-A expression is upregulated in mul ...
EPFL2023Multiomic analysis of HER2-enriched and AR-positive breast carcinoma with apocrine differentiation and an oligometastatic course: a case report
Breast carcinoma is the most prevalent cancer among women globally. It has variable clinical courses depending on the stage and clinical-biological features. This case report describes a 56-year-old female with invasive breast cancer without estrogen or pr ...
FRONTIERS MEDIA SA2023Gallocin A, an Atypical Two-Peptide Bacteriocin with Intramolecular Disulfide Bonds Required for Activity
Streptococcus gallolyticus subsp. gallolyticus (SGG) is an opportunistic gut pathogen associated with colorectal cancer. We previously showed that colonization of the murine colon by SGG in tumoral conditions was strongly enhanced by the production of gall ...
AMER SOC MICROBIOLOGY2023Statistical physics of periodic biological processes
Earth rotation around its axis imposes a 24-hour rhythmicity to all life on the planet.Rather than passively responding to these periodic changes, nature has given us an internal timekeeper, the circadian clock, to anticipate to our advantage the fluctuati ...
EPFL2023GCN2 adapts protein synthesis to scavenging-dependent growth
Pancreatic cancer cells with limited access to free amino acids can grow by scavenging extracellular protein. In a murine model of pancreatic cancer, we performed a genome-wide CRISPR screen for genes required for scavenging-dependent growth. The screen id ...
2022Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis
Didier Trono, Laurence Gouzi Abrami, Evaristo Jose Planet Letschert, Julien Léonard Duc, Laia Simo Riudalbas, Sandra Eloise Kjeldsen, Alexandre Coudray, Sagane Dind
The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...
