Miniature Inverted-Repeat Transposable Elements: Small DNA Transposons That Have Contributed to Plant MICRORNA Gene Evolution

Plants, 2023
Angiosperms form the largest phylum within the Plantae kingdom and show remarkable genetic variation due to the considerable difference in the nuclear genome size of each species.

Decoding m6Am by simultaneous transcription-start mapping and methylation quantification

eLife
N 6,2’-O-dimethyladenosine (m6Am) is a modified nucleotide located at the first transcribed position in mRNA and snRNA that is essential for diverse physiological processes. m6Am mapping methods assume each gene uses a single start nucleotide.

PICALM::MLLT10 translocated leukemia

FEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

An engineered U7 small nuclear RNA scaffold greatly increases ADAR-mediated programmable RNA base editing

Nature Communications
Custom RNA base editing exploiting the human Adenosine Deaminase Acting on RNA (ADAR) enzyme may enable therapeutic gene editing without DNA damage or use of foreign proteins.

Tumor educated platelet: the novel BioSource for cancer detection

Cancer Cell International, 2023
Platelets, involved in the whole process of tumorigenesis and development, constantly absorb and enrich tumor-specific substances in the circulation during their life span, thus called “Tumor Educated Platelets” (TEPs).

Cell density–dependent nuclear‐cytoplasmic shuttling of SETDB1 integrates with Hippo signaling to regulate YAP1‐mediated transcription

FEBS Letters, EarlyView.
At low cell density, SETDB1 and YAP1 accumulate in the nucleus. As cell density increases, the Hippo pathway is gradually activated, and SETDB1 is associated with increased YAP1 phosphorylation. At high cell density, phosphorylated YAP1 is sequestered in the cytoplasm, while SETDB1 becomes polyubiquitinated and degraded by the ubiquitin–proteasome ...

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Multiple pseudouridine synthase activities for small nuclear RNAs [PDF]

Biochemical Journal, 1993
The formation of pseudouridine (psi) in human U1, U2 and U5 small nuclear RNAs (snRNAs) was investigated using HeLa cell extracts. Unmodified snRNAs were synthesized in vitro and the extent of psi formation was determined after incubation in cell extracts. The formation of psi on labelled substrates was monitored in the presence of 5-fluorouracil (5-FU)

Pseudouridine formation in U2 small nuclear RNA. [PDF]

Proceedings of the National Academy of Sciences, 1994
U2 small nuclear RNA contains 13 pseudouridine (psi) nucleotides, of which 11 are clustered in 5' regions involved in base-pairing interactions with other RNAs in the spliceosome. As a first step toward understanding the psi formation pathway in U2 RNA, we investigated psi formation on unmodified human U2 RNA in a HeLa cell extract system.
