On modelling of bioavailability of drugs in terms of conservation laws [PDF]

arXiv, 2013
In the text S.Piekarski, M.Rewekant,(arXiv:1208.3847)it has been mentioned that some information on bioavailability and bioequivalence of drugs can be obtained from simulations based on the conservation laws. Here we shortly discuss that possibility starting from the fundamental pharmacokinetic parameter called AUC (Area Under the Curve).

Exploration of heterogeneity and recurrence signatures in hepatocellular carcinoma

Molecular Oncology, EarlyView.
This study leveraged public datasets and integrative bioinformatic analysis to dissect malignant cell heterogeneity between relapsed and primary HCC, focusing on intercellular communication, differentiation status, metabolic activity, and transcriptomic profiles.

Modeling and administration scheduling of fractional-order pharmacokinetic systems [PDF]

arXiv, 2017
Fractional-order dynamical systems were recently introduced in the field of pharmacokinetics where they proved powerful tools for modeling the absorption, disposition, distribution and excretion of drugs which are liable to anomalous diffusion, deep tissue trapping and other nonlinear phenomena.

The atypical KRASQ22K mutation directs TGF‐β response towards partial epithelial‐to‐mesenchymal transition in patient‐derived colorectal cancer tumoroids

Molecular Oncology, EarlyView.
TGF‐β has a complex role in cancer, exhibiting both tumor‐suppressive and tumor‐promoting properties. Using a series of differentiated tumoroids, derived from different stages and mutational background of colorectal cancer patients, we replicate this duality of TGF‐β in vitro. Notably, the atypical but highly aggressive KRASQ22K mutation rendered early‐

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

HODDI: A Dataset of High-Order Drug-Drug Interactions for Computational Pharmacovigilance [PDF]

arXiv
Drug-side effect research is vital for understanding adverse reactions arising in complex multi-drug therapies. However, the scarcity of higher-order datasets that capture the combinatorial effects of multiple drugs severely limits progress in this field. Existing resources such as TWOSIDES primarily focus on pairwise interactions.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

Molecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Increased Response Variability and Attentional Lapses After Chronic Cocaine Self-Administration [PDF]

, 2009
In humans, cocaine use has long been associated with poor attentional control and decreased efficiency in goal-oriented behavior. Animal models of these stereotypic drug effects, however, have thus far failed to produce quantifiable data sets in part ...

Cardiac Adverse Events in Patients Receiving Immune Checkpoint Inhibitors in the Adjuvant Setting: An FDA Pooled Analysis

Annals of Noninvasive Electrocardiology
Background Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment. By releasing blocks (checkpoints) on the immune system, they elicit powerful antitumor effects.
