Metabolic Singularities in Microsatellite-Stable Colorectal Cancer: Identifying Key Players in Immunosuppression to Improve the Immunotherapy Response.
Although immune checkpoint inhibitor (ICI) therapy is currently the standard of care in microsatellite-unstable (MSI) metastatic colorectal cancer (CRC), ICI therapy, alone or in combination with other therapies, is not a ...
Polo-like kinase 1 inhibitors in refractory colorectal cancer: deciphering the myth of synthetic lethality
Metastatic colorectal cancer (mCRC) remains a highly lethal disease because resistance to chemotherapy and targeted agents—including anti-VEGF and anti-EGFR therapies—emerges rapidly and universally. In RAS‑mutant mCRC, ...
Metabolic plasticity drives specific mechanisms of chemotherapy and targeted therapy resistance in metastatic colorectal cancer
Microsatellite-stable metastatic colorectal cancer (MSS mCRC) is currently treated with chemotherapy and targeted agents based on RAS and BRAF mutational status. Although these therapies offer initial benefit, most patients ...
Transcriptomic profiling of endothelial progenitor cells in post-COVID-19 patients: Insights at 3- and 6-month post-infection
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused significant global morbidity since 2019. Long COVID, characterized by persistent symptoms after acute infection, may involve endothelial injury. We ...
Design of a true bivalent ligand with picomolar affinity for a G protein-coupled receptor homodimer
Bivalent ligands have emerged as chemical tools to study G protein-coupled receptor dimers. Using a combination of computational, chemical, and biochemical tools, here we describe the design of bivalent ligand 13 with high ...
Towards biomimetic electrochromatography: Fast method for the Abraham's characterization of solute-solvent interactions in micellar and microemulsion electrokinetic systems
This study presents a fast method for the characterization of solute-solvent interactions in micellar and microemulsion electrokinetic chromatography based on the linear solvation energy relationships proposed by Abraham. ...
Intergenerational effects of maternal childhood maltreatment on newborns' stress regulation: The role of maternal depressive symptoms
Background: Maternal childhood maltreatment (CM) has been repeatedly associated with negative offspring's emotional outcomes. The dysregulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis has emerged as the main ...
rbfox1 LoF mutants show disrupted bdnf/trkb2 and crhb/nr3c2 expression and increased cortisol levels during development coupled with signs of allostatic overload in adulthood
Mutations in the RBFOX1 gene are associated with psychiatric disorders but how RBFOX1 influences psychiatric disorder vulnerability remains unclear. Recent studies showed that RBFOX proteins mediate the alternative splicing ...
Pleiotrophin as a central nervous system neuromodulator, evidences from the hippocampus
Pleiotrophin (PTN) is a secreted growth factor, and also a cytokine, associated with the extracellular matrix, which has recently starting to attract attention as a significant neuromodulator with multiple neuronal functions ...
3,4-Methylenedioxymethamphetamine enhances kainic acid convulsive susceptibility
Abstract Kainic acid (KA) causes seizures and neuronal loss in the hippocampus. The present study investigated whether a recreational schedule of 3,4-methylenedioxymethamphetamine (MDMA) favours the development of a seizure ...
Functional assessment of coding and regulatory variants from the DKK1 locus
The DKK1 gene encodes an extracellular inhibitor of the Wnt pathway with an important role in bone tissue development, bone homeostasis, and different critical aspects of bone biology. Several BMD genome-wide association ...
Reinterpreting anomalous competitive binding experiments within G protein-coupled receptor homodimers using a dimer receptor model
An increasing number of G protein-coupled receptors (GPCRs) have been reported to be expressed in the plasma membrane as dimers. Since most ligand binding data are currently fitted by classical equations developed only for ...
A heterobivalent ligand for the adenosine A2A-dopamine D2 receptor heteromer
A G protein-coupled receptor heteromer that fulfills the established criteria for its existence in vivo is the complex between adenosine A2A (A2AR) and dopamine D2 (D2R) receptors. Here, we have designed and synthesized ...
Unique pharmacodynamic properties and low abuse liability of the µ-opioid receptor ligand (S)-methadone
(R,S)-methadone ((R,S)-MTD) is a µ-opioid receptor (MOR) agonist comprised of (R)-MTD and (S)-MTD enantiomers. (S)-MTD is being developed as an antidepressant and is considered an N-methyl-D-aspartate receptor (NMDAR) ...
From Current Therapeutics to Multitarget Ligands: A Review of Diabetes Pharmacological Treatments
Diabetes is a chronic and complex pathological syndrome that includes a series of disorders and imbalances, whose first characterization is hyperglycemia, although, as it is a multifactorial phenomenon, it requires risk ...
S-acylation-dependent membrane microdomain localization of the regulatory Kvβ2.1 subunit
The voltage-dependent potassium (Kv) channel Kvβ family was the frst identifed group of modulators of Kv channels. Kvβ regulation of the α-subunits, in addition to their aldoketoreductase activity, has been under extensive ...
Conserved developmental expression of Fezf in chordates and Drosophila and the origin of the Zona Limitans Intrathalamica (ZLI) brain organizer
Background: The zona limitans intrathalamica (ZLI) and the isthmus organizer (IsO) are two major secondary organizers of vertebrate brain development. These organizers are located at the interface of the expression domains ...
HIF drives lipid deposition and cancer in ccRCC via repression of fatty acid metabolism
Clear cell renal cell carcinoma (ccRCC) is histologically defined by its lipid and glycogen-rich cytoplasmic deposits. Alterations in the VHL tumor suppressor stabilizing the hypoxiainducible factors (HIFs) are the most ...
Robustness of cosmic neutrino background detection in the cosmic microwave background
The existence of a cosmic neutrino background can be probed indirectly by CMB experiments, not only by measuring the background density of radiation in the universe, but also by searching for the typical signatures of the ...
