Landscape of mA RNA methylation regulators in liver cancer and its therapeutic implications.

Liver cancer remains as the third leading cause of cancer-related death globally as of 2020. Despite the significant progress made in the field of liver cancer treatment, there is still a lack of effective therapies in patients with advanced cancer and the molecular mechanisms underlying liver cancer progression remain largely elusive. N6-methyladenosine (mA) modification, as the most prevalent and abundant internal RNA modification in eukaryotic RNAs, plays an essential role in regulating RNA metabolism including RNA splicing, stability, translation, degradation.

[Aggregation Behavior of Collagen-Based Surfactant Molecules in Aqueous Solutions Based on Synchronization Fluorescence Spectrum Technology].

Due to the intrinsic fluorescence characteristic of tyrosine (Tyr) and phenylalanine (Phe), synchronization fluorescence spectrum technology which adopted the constant wavelength difference (Δλ = 15 nm) was selected to investigate the effects of collagen-based surfactant (CBS) concentration, pH, NaCt concentration and temperature on the aggregation state of CBS molecules in aqueous solutions. Meanwhile, temperature-dependent two-dimensional (2D) synchronization fluorescence correlation analyses was used to investigate the variation order of Tyr and Phe residues in CBS molecules with the change of temperature. The results showed that the characteristic absorption peaks located at 261 and 282 nm were attributed to Phe and Tyr, respectively.

Functional expression of xylose isomerase in flocculating industrial Saccharomyces cerevisiae strain for bioethanol production.

[Study on the effect of temperature on the conformation of cross-linked collagen by two-dimensional infrared correlation spectroscopy].

The Fourier transform infrared spectroscopy and two dimensional correlation analysis method were applied to study a denaturing process of uncross-linked collagen and cross-linked collagen during varying temperature. It was found that the intensity of typically characteristic absorptions of collagen decreased and its peak shifted to low frequency, The amide II central absorbance peak moved to a lower frequency by about 10 cm(-1), which indicated that the inter-chain hydrogen bonds which stabilized the triple helix conformation of collagen were disrupted during thermal denaturation, resulting in a conformational change. The intensity of auto-peak at 1 515 cm(-1) was maximum, which suggested that the temperature had a big impact on amide II.

Comparison of standard- and low-tube voltage 320-detector row volume CT angiography in detection of intracranial aneurysms with digital subtraction angiography as gold standard.

[Specific interaction study in collagen/hyaluronic acid blends by two-dimensional infrared correlation spectroscopy].

Conformational changes and specific interactions in the collagen/hyaluronic acid blends were studied by two-dimensional infrared correlation spectroscopy with the interruption of the component of hyaluronic acid in collagen/ hyaluronic acid blends. It was found that the synchronous cross-peaks, derived from stretching vibrations of C=O at 1 694 cm(-1), wagging of N-H at 1 524 cm(-1) and in-plane deformation of N-H at 1 241 cm(-1) of collagen, were indicative of local conformational changes of collagen. The synchronous negative cross-peak between stretching vibrations of C-OH of hyaluronic acid at 1 045 cm(-1) and streching vibrations of C=O of collagen at 1 694 cm(-1) suggested that the interaction of hydrogen bonding existing between O-H of HA and C=O of collagen with the content of HA varied from 0% to 50%.
