Engineering VIGS Vectors by Modifying Movement Proteins of the 30K Family. [PDF]

Biotechnol J
Graphical Abstract and Lay Summary Silencing of plant genes is achieved by inserting small sequences of the target gene into the open reading frame of viral movement proteins belonging to the 30K family. Depending on the size of the insert, the silencing efficiency is around 45% for fragments ranging from 21 to 39 nucleotides, 65% for a 42‐nucleotide ...

Unveiling nuclear localization signals in human arginine deiminase proteins. [PDF]

Protein Sci
Abstract Arginine iminohydrolases are a family of enzymes involved in the conversion of arginine to citrulline. There are five isoforms in humans (PADI1, 2, 3, 4, and 6). Some of them are observed experimentally in the cytoplasm and in the nucleus of the cell; for moving to the latter location, they must pass through the cell nuclear membrane by using ...

Guidelines for the purification and characterization of extracellular vesicles of parasites

Journal of Extracellular Biology, Volume 2, Issue 10, October 2023., 2023
Abstract Parasites are responsible for the most neglected tropical diseases, affecting over a billion people worldwide (WHO, 2015) and accounting for billions of cases a year and responsible for several millions of deaths. Research on extracellular vesicles (EVs) has increased in recent years and demonstrated that EVs shed by pathogenic parasites ...

Silver‐Based Terpyridine Complexes as Antitumor Agents

Chemistry – A European Journal, Volume 29, Issue 37, July 3, 2023., 2023
A family of 4’‐X‐terpyridines/tetra‐2‐pyridinylpyrazine silver derivatives with or without phosphines as ancillary ligands has shown high cytotoxicity against different tumour cells. In addition, a great selectivity index has been detected for healthy lymphocytes T in some cases.

Genomics in neglected and underutilized fruit crops: A chromosome‐scale genome sequence of cherimoya (Annona cherimola)

PLANTS, PEOPLE, PLANET, Volume 5, Issue 3, Page 408-423, May 2023., 2023
Cherimoya has been an important food source since Pre‐Columbian times in the Americas. Although it is currently considered an underutilized fruit crop, it is still important at the local level in several regions of Central and South America, and has a clear niche for expansion in regions with subtropical climates.
