Virus evolution : the emergence of new ideas (and re-emergence of old ones)
, 2006 Reputed intractable, the question of the origin of viruses has long been neglected. In the modern literature 'Virus evolution' has come to refer to study more akin to population genetics, such as the world-wide scrutiny on new polymorphisms appearing ...

A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme
Advanced Science, EarlyView.The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

Switch on the engine: how the eukaryotic replicative helicase MCM2–7 becomes activated
, 2014 © 2014, Springer-Verlag Berlin Heidelberg.A crucial step during eukaryotic initiation of DNA replication is the correct loading and activation of the replicative DNA helicase, which ensures that each replication origin fires only once.

Advanced Science, EarlyView.This study unveils a novel GAA (GCN5‐ADA2‐ACL) complex that forms nuclear condensates to boost local acetyl‐CoA, facilitating histone acetylation and gene transcription in rice meristems. The research underscores the role of ADA2's disordered region in complex condensation and ACL's role in acetyl‐CoA production.

Advanced Science, EarlyView.This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

USP35 Acts as a Deubiquitinating Enzyme for ID3 to Promote Immune Escape in Colorectal Cancer
Advanced Science, EarlyView.USP35 stabilizes ID3 expression by deubiquitinating the K2/K30 site, thereby upregulating PD‐L1 and promoting immune escape in colorectal cancer. IU1, an inhibitor of USP35 enzyme activity, has been shown to inhibit USP35, thereby accelerating ID3 degradation, enhancing CD8+ T cell killing, and reversing the immunosuppressive microenvironment ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]
, 2009 The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...

Advanced Science, EarlyView.This study identifies TOPK as a dual‐function target in gastric cancer: it drives tumor cell proliferation and migration, and under IFN‐γ stimulation, phosphorylates eIF4F complex component eIF4A1 to enhance STAT1 mRNA translation, thereby promoting PD‐L1/IDO1‐mediated tumor immunometabolic evasion.
