Classification of the Biogenicity of Complex Organic Mixtures for the Detection of Extraterrestrial Life

open access: yesLife, 2021
Searching for life in the Universe depends on unambiguously distinguishing biological features from background signals, which could take the form of chemical, morphological, or spectral signatures.

MiR-483-3p regulates oxaliplatin resistance by targeting FAM171B in human colorectal cancer cells

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2019
Oxaliplatin resistance limits the efficiency of treatment for colorectal cancer (CRC). Studies have shown that abnormal expression of microRNAs (miRNAs) were associated with tumorigenesis, cancer development and chemoresistance. The purpose of this study

Universal Biosignatures for the Detection of Life [PDF]

open access: yes, 2005
My goal is to identify processes of life that leave measurable effects on an organism's environment, but which are not tied to any particular biochemistry, in order to build a conceptual framework for the search for extraterrestrial life.
