Shaping electrospray plume with convergent sound beams

open access: yesiScience
Summary: Electrospray ionization (ESI) is one of the mainstream ionization techniques for mass spectrometry (MS) nowadays. Here, we present a new variant of ESI-MS setup, in which an electrospray emitter points to the mass spectrometer’s orifice while ...

A Mass Spectrometry Approach Reveals Fatty Acid Isomerism in Tomato Cold Tolerance

open access: yesAdvanced Science, EarlyView.
An enhanced mass spectrometry approach reveals fatty acids (FAs) and FA isomers that are critical for tomato cold tolerance. Applying specific FA isomers can partially rescue cold sensitivity in tomato mutant plants, highlighting the importance of FA isomers in plant cold stress adaptation.

RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.
