Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

IFI27 and BAX are Essential for GSDME‐Mediated Myeloma Cell Pyroptosis

Advanced Science, EarlyView.
The proposed model of GSDME‐mediated MM cell pyroptosis modulated by IFI27 and BAX. IFI27 is downregulated in MM cells. Upon pyroptotic stimulation, such as DOX or ETO treatment, IFI27 is induced, therefore liberating BAX from BCL‐2 ❶. BAX is then recruited to mitochondria and forms homo‐oligomeric channels in OMM, therefore leading to cytochrome C ...

Carrier‐Free Berberine/Nitidine Chloride Self‐Assembled Nanoparticles Induce Ferroptosis to Overcome Bortezomib Resistance in Multiple Myeloma

Advanced Science, EarlyView.
A schematic illustrating the fabrication process and ferroptosis‐mediated therapeutic mechanism of carrier‐free self‐assembled BBR/NC‐SAPs for overcoming bortezomib resistance in multiple myeloma. ABSTRACT Therapeutic relapse driven by bortezomib resistance represents a formidable clinical barrier in the management of multiple myeloma (MM).

Somatic Mutations and Alzheimer’s Disease

Journal of Alzheimer's Disease, 2022
Alzheimer’s disease (AD) represents a global health challenge, with an estimated 55 million people suffering from the non-curable disease across the world. While amyloid-β plaques and tau neurofibrillary tangles in the brain define AD proteinopathy, it has become evident that diverse coding and non-coding regions of the genome may significantly ...

Somatic Mutation and Aging

Annals of the New York Academy of Sciences, 1998
ABSTRACT: A key prediction of the somatic mutation theory of aging is that there is an invariant relationship between life span and the number of random mutations. A number of studies at a number of gene loci have shown that somatic mutations of a variety of types accumulate with age.

Somatic mutations and proteins

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1966
Abstract A large body of data has now been accumulated concerning the ways in which heritable mutations can affect protein structure. Such mutations are usually presumed to arise in the germ line, and are studied by progeny analyses of various types.

Somatic mutation theory

Journal of Toxicology and Environmental Health, 1980
The evidence is reviewed that supports the role of genetic lesions in carcinogenesis; such lesions may be initiating events in the multistep process leading to clinically detectable tumor. Other possible manifestations of alterations in the hereditary material of somatic cells are discussed; DNA damage may lead to benign tumors responsible for ...

Somatic mutation and memory

Current Opinion in Immunology, 1993
The germinal center plays a crucial role in the development of the memory B cell. The repertoire of the antigen-specific B cell is shaped in this microenvironment. Self-specific B cells escaping normal regulation may develop into high affinity pathogenic Ig-producing cells.

Review: Somatic mutations in neurodegeneration

Neuropathology and Applied Neurobiology, 2018
Somatic mutations are postzygotic mutations which may lead to mosaicism, the presence of cells with genetic differences in an organism. Their role in cancer is well established, but detailed investigation in health and other diseases has only been recently possible.
