A novel micropeptide miPEP205 suppresses the growth and metastasis of TNBC.

Triple negative breast cancer (TNBC) is the most aggressive subtype of breast cancer and poses a treatment challenge due to high recurrence risk. Consequently, there is an urgent need for novel and efficacious therapies targeting TNBC. In this context, our study delineates the identification and characterization of a long non-coding RNA (lncRNA)-derived micropeptide miPEP205.

LncRNA-Encoded Micropeptide ACLY-BP Drives Lipid Deposition and Cell Proliferation in Clear Cell Renal Cell Carcinoma via Maintenance of ACLY Acetylation.

Unlabelled: Clear cell renal cell carcinoma (ccRCC) is the most common subtype of lethal kidney cancer. Reprogramming of fatty acid and glucose metabolism resulting in the accumulation of lipids and glycogen in the cytoplasm is a hallmark of ccRCC. Here, we identified a micropeptide ACLY-BP encoded by the GATA3-suppressed LINC00887, which regulated lipid metabolism and promoted cell proliferation and tumor growth in ccRCC.

Discrimination between Carbapenem-Resistant and Carbapenem-Sensitive Klebsiella pneumoniae Strains through Computational Analysis of Surface-Enhanced Raman Spectra: a Pilot Study.

In clinical settings, rapid and accurate diagnosis of antibiotic resistance is essential for the efficient treatment of bacterial infections. Conventional methods for antibiotic resistance testing are time consuming, while molecular methods such as PCR-based testing might not accurately reflect phenotypic resistance. Thus, fast and accurate methods for the analysis of bacterial antibiotic resistance are in high demand for clinical applications.

Comparative Analysis of Machine Learning Algorithms on Surface Enhanced Raman Spectra of Clinical Species.

Raman spectroscopy (RS) is a widely used analytical technique based on the detection of molecular vibrations in a defined system, which generates Raman spectra that contain unique and highly resolved fingerprints of the system. However, the low intensity of normal Raman scattering effect greatly hinders its application. Recently, the newly emerged surface enhanced Raman spectroscopy (SERS) technique overcomes the problem by mixing metal nanoparticles such as gold and silver with samples, which greatly enhances signal intensity of Raman effects by orders of magnitudes when compared with regular RS.

Applications of Raman Spectroscopy in Bacterial Infections: Principles, Advantages, and Shortcomings.

Infectious diseases caused by bacterial pathogens are important public issues. In addition, due to the overuse of antibiotics, many multidrug-resistant bacterial pathogens have been widely encountered in clinical settings. Thus, the fast identification of bacteria pathogens and profiling of antibiotic resistance could greatly facilitate the precise treatment strategy of infectious diseases.
