From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

open access: yesFEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Non-canonical function of DGCR8 in DNA double-strand break repair signaling and tumor radioresistance

open access: yesNature Communications, 2021
The molecular mechanisms underlying cancer cell radioresistance need to be elucidated. In this study, the authors show that the microRNA biogenesis factor DGCR8 is stabilized by USP51 and ATM upon irradiation and by consequence it promotes the repair of ...

microRNA biogenesis and function in plants [PDF]

open access: yesFEBS Letters, 2005
A microRNA (miRNA) is a 21–24 nucleotide RNA product of a non‐protein‐coding gene. Plants, like animals, have a large number of miRNA‐encoding genes in their genomes. The biogenesis of miRNAs in Arabidopsis is similar to that in animals in that miRNAs are processed from primary precursors by at least two steps mediated by RNAse III‐like enzymes and ...

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

open access: yesAging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

FIERY1 promotes microRNA accumulation by suppressing rRNA-derived small interfering RNAs in Arabidopsis

open access: yesNature Communications, 2019
Arabidopsis AGO1 binds both microRNA (miRNA) and endogenous small interfering RNA (siRNA). Here the authors show that 5′−3′ RNA degradation suppresses siRNA biogenesis from ribosomal RNA to prevent overloading of AGO1 with ribosomal siRNA and maintain ...

Research Progress of Mitochondrial-Mediated Docosahexaenoic Acid (DHA) Antioxidation

open access: yesShipin gongye ke-ji, 2022
Docosahexaenoic acid (DHA) is an essential omega-3 polyunsaturated fatty acid (PUFA) for human body, which is highly rich in deep sea fish oil and marine microalgae. Mitochondria are the energy factory of cells. Mitochondrial functions and biogenesis can

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Stabilizing heterochromatin by DGCR8 alleviates senescence and osteoarthritis

open access: yesNature Communications, 2019
DGCR8 is a component of the canonical microprocessor complex for microRNA biogenesis. Here the authors implicate DGCR8 in heterochromatin maintenance and aging attenuation independent of its miRNA-processing activity through Lamin B1, KAP1 and HP1 ...

TWIST1 induces phenotypic switching of vascular smooth muscle cells by downregulating p68 and microRNA‐143/145

open access: yesFEBS Open Bio, 2021
TWIST1 is an important basic helix‐loop‐helix protein linked to multiple physiological and pathological processes. Although TWIST1 is believed to be involved in vascular pathogenesis, its effects on homeostasis of smooth muscle cells (SMCs) remain poorly
