Abstract Background Intrahepatic cholangiocarcinoma (ICC) is a challenging cancer with an increasing incidence. The Phase III TOPAZ‐1/KEYNOTE‐966 study demonstrated chemo‐immunotherapy (CIT) as a significant advancement, potentially replacing traditional chemotherapy for advanced biliary tract cancer.

Methods for Controlling Small GTPase Activity
This concept highlights recent and emerging methods for controlling small GTPase activity, encompassing both small‐molecule‐based approaches and protein engineering strategies. The use of these approaches to advance the understanding of small GTPase function, current limitations, and future outlook is discussed.

The Link between Purine Metabolism and Production of Antibiotics in Streptomyces
Stress and starvation causes bacterial cells to activate the stringent response. This results in down-regulation of energy-requiring processes related to growth, as well as an upregulation of genes associated with survival and stress responses. Guanosine

Cyclic guanosine monophosphate as a mediator of vasodilation.
Although cyclic guanosine monophosphate (GMP)' was first described in biological samples more than two decades ago, its role in some physiological processes has only become apparent in the past few years (see references 1-4).

Synthesis of Nucleoside Derivatives by Biomimetic Ester Migration
In tRNA aminoacylated nucleosides represent the central transfer unit of amino acids. An occurring 2′‐3′‐transaminoacylation is biomimetically exploited to successfully synthesize nucleosidic acid esters. This approach can be further expanded on sulfonic acid esters, which has the potential of a broad range of stereo‐ and regio‐controlled modifications
