Biogenesis of cytochrome c1 [PDF]
The biogenesis of cytochrome c1 involves a number of steps including: synthesis as a precursor with a bipartite signal sequence, transfer across the outer and inner mitochondrial membranes, removal of the first part of the presequence in the matrix ...

Extracellular antifreeze protein significantly enhances the cryopreservation of cell monolayers [PDF]
The cryopreservation of cells underpins many areas of biotechnology, healthcare, and fundamental science by enabling the banking and distribution of cells. Cryoprotectants are essential to prevent cold-induced damage.

ABSTRACT Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR).

Targeting Tumor Dormancy and Recurrence: Molecular Mechanisms and Peptide Therapeutic Delivery
This review summarizes the molecular mechanisms that regulate tumor dormancy and its role in cancer recurrence, with emphasis on immune evasion, extracellular matrix remodeling, metabolic regulation and angiogenic switching. It further discusses emerging peptide–based therapeutic strategies aimed at detecting, modulating, and eliminating dormant tumor ...

Tumor‐associated macrophages are the most abundant immune cells in the tumor microenvironment, driving malignant progression and treatment resistance. This review summarizes the protumor mechanisms of TAMs (including phagocytosis modulation, metabolic reprogramming, exosomal communication, and immune interactions), evaluates three major strategies ...

Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling. [PDF]
Light initiates chloroplast biogenesis by activating photosynthesis-associated genes encoded by not only the nuclear but also the plastidial genome, but how photoreceptors control plastidial gene expression remains enigmatic.

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

Glyphosate resistance in annual ryegrass (Lolium rigidum Gaud.) with multiple resistance mechanisms. [PDF]
Glyphosate (N-(phosphonomethyl)glycine) is a post-emergent, systemic and non-selective herbicide for the control of annual and perennial weeds. This herbicide has very low toxicity to the mammals.

Optimization of ClpXP activity and protein synthesis in an E. coli extract-based cell-free expression system. [PDF]
Protein degradation is a fundamental process in all living cells and is essential to remove both damaged proteins and intact proteins that are no longer needed by the cell.

Cell-Penetrating Peptides, Electroporation, and Drug Delivery
Certain short polycations, such as TAT and oligoarginine, rapidly pass through the plasma membranes of mammalian cells by a mechanism called transduction, as well as by endocytosis and macropinocytosis.
