Ribosome transfer via tunnelling nanotubes rescues protein synthesis in pancreatic cancer cells Background: Pancreatic ductal adenocarcinoma (PDAC) is considered as one of the deadliest types of cancer. Tunnelling nanotubes (TNTs) are thin, membranous, intercellular communication structures obse...

Our significantly expanded preprint is out. In it we show that pancreatic cancer cells can transfer ribosomes via tunnelling nanotubes and rescue protein synthesis when co-cultured with cells with impaired ribosomal biogenesis.

Portrait of Rachel Green, an RNA biologist at Johns Hopkins University

“What a [sunburned] cell is trying to do is make decisions about whether to live or die based on how damaged the DNA is… but amazingly, it’s the RNA that signals that. That’s the remarkable observation.” — Rachel Green, biologist at Johns Hopkins University.

Structures of Naked Mole-Rat, Tuco-Tuco, and Guinea Pig Ribosomes: Is rRNA Fragmentation Linked to Translational Fidelity? Ribosomes are central to protein synthesis in all organisms. Among mammals, the ribosome functional core is highly conserved. Remarkably, two rodent species, the naked mole-rat (NMR) and tuco-tuco dis...

The USA is fourth; 20% of the USA population is Catholic (68 million). Clearly, as you will discuss, there is political stuff involved here. I have the feeling that we are still seeing colonialism.

Brazil has a population of 123 million Catholics (70% of its population), followed by Mexico and the Philippines (80% of their population). None of these countries has had a Pope.
