Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Endoscopic submucosal dissection in the West

open access: yesInternational Journal of Gastrointestinal Intervention, 2019
Endoscopic resection has emerged as the first line therapy for pre-malignant conditions throughout the gastrointestinal (GI) tract. Resection techniques have evolved from forceps avulsion and snare polypectomy to endoscopic mucosal resection (EMR) and ...

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Hierarchical Phenotyping and Graph Modeling of Spatial Architecture in Lymphoid Neoplasms [PDF]

open access: yesarXiv, 2021
The cells and their spatial patterns in the tumor microenvironment (TME) play a key role in tumor evolution, and yet the latter remains an understudied topic in computational pathology. This study, to the best of our knowledge, is among the first to hybridize local and global graph methods to profile orchestration and interaction of cellular components.

Mucosubstances in neoplasms of the human colon and rectum [PDF]

open access: yesGut, 1971
The patterns of mucosubstances secreted in the normal human colon and rectum, in benign tumours, and in and around malignant tumours of the colon and rectum have been studied. Very little neutral mucosubstance was seen in normal specimens; the secretion in these was made up of sulphated and nonsulphated acid mucosubstances, with the former ...

Tumor heterogeneity in neoplasms of breast, colon, and skin [PDF]

open access: yesBMC Research Notes, 2010
Different cell subpopulations in a single tumor may show diverse capacities for growth, differentiation, metastasis formation, and sensitivity to treatments. Thus, heterogeneity is an important feature of tumors. However, due to limitations in experimental and analytical techniques, tumor heterogeneity has rarely been studied in detail.Different tumor ...

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

On the proper treatment of pathologies in biomedical ontologies [PDF]

open access: yes, 2005
In previous work on biomedical ontologies we showed how the provision of formal definitions for relations such as is_a and part_of can support new types of auto-mated reasoning about biomedical phenomena.

Preoperative localization of potentially invisible colonic lesions on the laparoscopic operation field: using autologous blood tattooing [PDF]

open access: yesAnnals of Coloproctology
Purpose Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used.
