A UTP3-dependent nucleolar translocation pathway facilitates pre-rRNA 5'ETS processing.

The ribosome small subunit (SSU) is assembled by the SSU processome which contains approximately 70 non-ribosomal protein factors. Whilst the biochemical mechanisms of the SSU processome in 18S rRNA processing and maturation have been extensively studied, how SSU processome components enter the nucleolus has yet to be systematically investigated. Here, in examining the nucleolar localization of 50 human SSU processome components, we found that UTP3, together with another 24 proteins, enter the nucleolus autonomously.

Within this context, specific miRNAs have been identified as indirect mediators of immune functions through their modulation of autophagy.

miR-22a targets p62/SQSTM1 to negatively affect autophagy and disease resistance of grass carp (Ctenopharyngodon idella).

MicroRNAs (miRNAs) are integral to many biological functions, including autophagy, a process recently proven to be closely linked to innate immunity. In this study, we present findings on miR-22a, a teleost homolog of mammalian miR-22, illustrating its capacity to target the autophagy adaptor p62, subsequently inducing downregulation at both mRNA and protein levels. Utilizing Western blot analyses, we demonstrated that miR-22a inhibits the autophagy flux of CIK cells, correlated with an elevated presence of LC3 II.

Recent Advances in Nano-Formulations for Skin Wound Repair Applications.

Skin injuries caused by accidents and acute or chronic diseases place a heavy burden on patients and health care systems. Current treatments mainly depend on preventing infection, debridement, and hemostasis and on supplementing growth factors, but patients will still have scar tissue proliferation or difficulty healing and other problems after treatment. Conventional treatment usually focuses on a single factor or process of wound repair and often ignores the influence of the wound pathological microenvironment on the final healing effect.

Tween 20-capped gold nanoparticles for selective extraction of free low-molecular-weight thiols in saliva followed by capillary electrophoresis with contactless conductivity detection.

Low-molecular-weight thiols are widely present in human fluids, and are regarded as a kind of potential broad-spectrum evaluation indicators for some clinical diseases. In this work, gold nanoparticles capped with Tween 20 were used for purification and microextraction of the main free thiols (cysteine, homocysteine, glutathione and methionine) in saliva based on Au-S bond formation. Ultrasound further sped up the releasing of the target analytes, and the releasing time needed was only 10 min, and the required sample volume was only 40 µL.

Cdc20 hypomorphic mice fail to counteract de novo synthesis of cyclin B1 in mitosis.

Cdc20 is an activator of the anaphase-promoting complex/cyclosome that initiates anaphase onset by ordering the destruction of cyclin B1 and securin in metaphase. To study the physiological significance of Cdc20 in higher eukaryotes, we generated hypomorphic mice that express small amounts of this essential cell cycle regulator. In this study, we show that these mice are healthy and not prone to cancer despite substantial aneuploidy.

Emergent epileptiform activity in neural networks with weak excitatory synapses.

Brain electrical activity recorded during an epileptic seizure is frequently associated with rhythmic discharges in cortical networks. Current opinion in clinical neurophysiology is that strongly coupled networks and cellular bursting are prerequisites for the generation of epileptiform activity. Contrary to expectations, we found that weakly coupled cortical networks can create synchronized cellular activity and seizure-like bursting.
