Visualization of Endosomal Escape of Intracellularly Delivered Protein With Unexpected Photochemical Internalization of Trypan Blue

Advanced Science, EarlyView.
TB, a conventional cell viability dye, acts as both a fluorescence modulator (quenching GFP fluorescence upon protein binding and recovering it upon release) and a photosensitizer that triggers endosomal escape via photochemical internalization (PCI) under 590 nm light.

Phytochemistry and Biological Activities of Agrostemma Genus—A Review

Plants
The family Caryophyllaceae comprises more than 2600 species spread widely across all the continents. Their economic importance is mainly as ornamentals (carnation) and as weeds in agriculture. Some species have been used traditionally (and some are still)

Small-molecule inhibitor leads of ribosome-inactivating proteins developed using the doorstop approach. [PDF]

PLoS ONE, 2011
Ribosome-inactivating proteins (RIPs) are toxic because they bind to 28S rRNA and depurinate a specific adenine residue from the α-sarcin/ricin loop (SRL), thereby inhibiting protein synthesis.

LRP1-Mediated Endocytosis May Be the Main Reason for the Difference in Cytotoxicity of Curcin and Curcin C on U2OS Osteosarcoma Cells

Toxins, 2022
Curcin and Curcin C, both of the ribosome-inactivating proteins of Jatropha curcas, have apparent inhibitory effects on the proliferation of osteosarcoma cell line U20S.

Modification of ribosomal RNA by ribosome-inactivating proteins from plants [PDF]

Nucleic Acids Research, 1988
We have surveyed 14 different toxic and nontoxic ribosome-inactivating proteins from plants for the ability to act on the RNA of the eucaryotic 60 S ribosomal subunit. All of these proteins act to introduce a specific modification into 26-28 S RNA which renders the RNA sensitive to cleavage by aniline.

Reduced Maintenance DNA Methylation Thresholds Enable Sensitive Reporter Assays for UHRF1 and DNMT1 Inhibition

Advanced Science, EarlyView.
The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

Two complementary approaches for intracellular delivery of exogenous enzymes. [PDF]

, 2015
Intracellular delivery of biologically active proteins remains a formidable challenge in biomedical research. Here we show that biomedically relevant enzymes can be delivered into cells using a new DNA transfection reagent, lipofectamine 3000, allowing ...

N4‐acetylcytidine in LncRNA Gm26917 Promotes Translation in Female Germline Stem Cells by Recruiting Ribosomal Protein mRNA via EEF1A1

Advanced Science, EarlyView.
This work establishes that ac4C modification on lncRNA Gm26917 governs its spatial interactions with Rpl10 mRNA, and RBP EEF1A1 mediates the interaction between Gm26917 and Rpl10. It elucidates a novel ac4C‐Gm26917‐EEF1A1‐Rpl10 axis in FGSC maintenance both in vitro and in vivo, and provides a potential molecular target for modulating germ cell ...

In-silico analysis of ribosome inactivating protein (RIP) of the Cucurbitaceae family

AMB Express
Ribosome-inactivating proteins (RIPs) are highly active N-glycosidases that depurinate both bacterial and eukaryotic rRNAs, halting protein synthesis during translation.
