Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Emerging connections between small RNAs and phytohormones [PDF]
, 2020 Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

A Highly Sensitive Plant Hybrid Protein Assay System Based on the \u3cem\u3eSpm\u3c/em\u3e Promoter and TnpA Protein for Detection and Analysis of Transcription Activation Domains [PDF]
, 1996 TnpA is a multifunctional DNA binding protein encoded by the maize Suppressor-mutator (Spm) transposable element. TnpA is required for transposition and is a repressor of the unmethylated Spm promoter.

FEBS Letters, EarlyView.The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Ancient plant DNA: review and prospects [PDF]
New Phytologist, 2005 SummaryAncient DNA has received much attention since the mid‐1980s, when the first sequence of an extinct animal species was recovered from a museum specimen. Since then, the majority of ancient DNA studies have focused predominantly on animal species, while studies in plant palaeogenetics have been rather limited, with the notable exception of ...

Isolation of a transcriptionally active element of high copy number retrotransposons in sweetpotato genome [PDF]
, 2004 Many plant retrotransposons have been characterized, but only three families (Tnt1, Tto1 and Tos17) have been demonstrated to be transpositionally competent.
