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

Artificial 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

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

Life, 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.

The Grayness of the Origin of Life [PDF]

, 2021
In the search for life beyond Earth, distinguishing the living from the non-living is paramount. However, this distinction is often elusive, as the origin of life is likely a stepwise evolutionary process, not a singular event.

MEMS GC Column Performance for Analyzing Organics and Biological Molecules for Future Landed Planetary Missions

Frontiers in Astronomy and Space Sciences, 2022
We present a novel, innovative approach to gas chromatography-mass spectrometry (GC-MS) based on micro-electro-mechanical systems (MEMS) columns that improve the current, state-of-the-art by dramatically reducing the size, mass, and power resources for ...

Universal Biosignatures for the Detection of Life [PDF]

, 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.

Immunological detection of small organic molecules in the presence of perchlorates: relevance to the life marker chip and life detection on Mars. [PDF]

, 2011
The proposed ExoMars mission, due to launch in 2018, aims to look for evidence of extant and extinct life in martian rocks and regolith. Previous attempts to detect organic molecules of biological or abiotic origin on Mars have been unsuccessful ...

Detecting nanoscale vibrations as signature of life [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance The quest to find life in extreme and extraterrestrial environments is exciting and touches many research fields. One of the common signatures of life is movement: Even small microorganisms vibrate in response to their metabolic activity.
