Inhibitor of DNA binding‐1 is a key regulator of cancer cell vasculogenic mimicry
Elevated expression of transcriptional regulator inhibitor of DNA binding 1 (ID1) promoted cancer cell‐mediated vasculogenic mimicry (VM) through regulation of pro‐angiogenic and pro‐cancerous genes (e.g. VE‐cadherin (CDH5), TIE2, MMP9, DKK1). Higher ID1 expression also increased metastases to the lung and the liver.

Positive solutions for elliptic equations with singular nonlinearity
We study an elliptic boundary-value problem with singular nonlinearity via the method of monotone iteration scheme: $$displaylines{ -Delta u(x)=f(x,u(x)),quad x in Omega,cr u(x)=phi(x),quad x in partial Omega , }$$ where $Delta$ is the Laplacian ...

Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

Positive solutions of a class of linear systems
This delightful paper consists of a useful sufficient condition in order that the solution of a linear algebraic system have positive components and explains how this result applies directly to ecological models. For the matrices A, \(m\times m\), B, \(m\times n-m\), C, n-m\(\times m\), D, n-m\(\times n-m\), x, \(m\times 1\), y, n-m\(\times 1\), f, \(m\

This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...
