Background: Exploring the mechanisms underlying sorafenib resistance that arises in hepatocellular carcinoma (HCC) may provide new treatment perspectives.
Methods: Drug-resistant and drug-sensitive HCC cell lines were constructed from existing HepG2 and Huh7 cell lines, and gene expression profiles were determined. Genes differentially expressed between the resistant and sensitive lines were identified and organized into modules based on weighted gene co-expression network analysis.
Tuberculosis (TB), induced by Mycobacterium tuberculosis (Mtb) infection, remains one of the top killers among infectious diseases. The pathogenesis hallmarks for TB are complex immune escape mechanisms of Mtb and low targeting effects of anti-TB drugs. cGAS signaling, which is responsible for triggering host antibacterial immunity against Mtb infection, has shown potentials to serve as targets for anti-TB immunotherapy.

Now, we present the second reported case of LCH found in the right intermediate bronchus, characterized by calcification within the lesion and cystic changes. These distinctive features should alert clinicians to consider LCH in the differential diagnosis of other benign vascular tumors and mediastinal lymphadenopathy, particularly when calcified and cystic lesions are observed.

Herein, we achieved the transformation of non-ferromagnetic α-FeO into ferromagnetic CoFeO by Co doping. Compared to α-FeO, the OER activity of CoFeO considerably increased under a magnetic field of 3000 Oe and is proportional to the magnetic field strength within a certain range.

The primary pathogenic mechanism of POAG involves elevated intraocular pressure caused by chronic fibrosis of the trabecular meshwork (TM). Autophagy, a critical process for maintaining cellular homeostasis, has been implicated in fibrosis across various organs.

Especially, the CRISPR-Cas12 system has shown exceptional clinical diagnosis and gene editing capabilities. Here, we discovered that although the top loop of the 5' handle of guide RNA can undergo central splitting, deactivating CRISPR-Cas12a, the segments can dramatically restore CRISPR function through nucleic acid self-assembly or interactions with small molecules and aptamers.

Materials And Methods: A ligature-induced peri-implantitis murine model was established using an immediate implant placement approach. RNA sequencing was performed to determine the transcriptomic profiles of peri-implant tissues from mice, patients with peri-implantitis and healthy individuals.
While circular RNAs (circRNAs) exhibit lower abundance compared to corresponding linear RNAs, they demonstrate potent biological functions. Nevertheless, challenges arise from the low concentration and distinctive structural features of circRNAs, rendering existing methods operationally intricate and less sensitive. Here, we engineer an intelligent tetrahedral DNA framework (TDF) possessing precise spatial pattern-recognition properties with exceptional sensing speed and sensitivity for circRNAs.

Currently, over 170 distinct chemical modifications have been identified in mRNAs, tRNAs, rRNAs, microRNAs (miRNAs), and long noncoding RNAs (lncRNAs). Genetic and molecular studies have identified the genes responsible for addition and removal of chemical modifications from RNA molecules, which are known as "writers" and "erasers," respectively.

Due to the higher work function of NiB, facile-directed electron transport occurs from PtNi to NiB to enrich electron density on the surface of the NiB shell. This process increases hydrogen adsorption-desorption kinetics and mitigates Cl corrosion.

Disruption of cerebral blood flow impairs oxygen and energy substrate delivery, leading to mitochondrial oxidative phosphorylation dysfunction and cellular bioenergetic stress. Investigating the effects of circSCMH1, a brain repair-related circular RNA, on metabolism may identify novel therapeutic targets for stroke treatment.

The accelerated deterioration of carbonate stone artifacts under climate change has long been an urgent issue. Inspired by biomineralization, we developed carboxymethyl chitosan-diammonium hydrogen phosphate (CD) composite and investigated the conservation effectiveness of the CD composite compared to diammonium hydrogen phosphate (DAP) on limestone. The morphologies and microstructures were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR).

Insufficient cerebral blood supply can induce poly (ADP-ribose) polymerase (PARP) activation and mitochondrial dysfunction, leading to tissue damage and motor dysfunction. We demonstrate that the expression of TCDD inducible PARP (TIPARP) is elevated in ischemic stroke patients and mice.

Our knowledge on the forming of chronic pain mostly derives from mechanistic studies of pain processing in the brain and spinal cord circuits, yet most pharmacological interventions targeting CNS came to be unhelpful in preventing CPSP. Revealing the peripheral mechanisms behind the transition from acute to chronic pain after surgery could shine a light on the novel analgesic regimens.
