Abstract Background Treatment options for Chinese patients with locally advanced or metastatic squamous‐cell non‐small‐cell lung cancer (sqNSCLC) after failure of first‐line chemotherapy are limited. This study (ORIENT‐3) aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second‐line treatment in patients with locally advanced ...

AP-1 as a Regulator of MMP-13 in the Stromal Cell of Giant Cell Tumor of Bone
Matrix-metalloproteinase-13 (MMP-13) has been shown to be an important protease in inflammatory and neoplastic conditions of the skeletal system. In particular, the stromal cells of giant cell tumor of bone (GCT) express very high levels of MMP-13 in ...

Exact distributions for stochastic models of gene expression with arbitrary regulation [PDF]
Stochasticity in gene expression can result in fluctuations in gene product levels. Recent experiments indicated that feedback regulation plays an important role in controlling the noise in gene expression. A quantitative understanding of the feedback effect on gene expression requires analysis of the corresponding stochastic model.

Gene expression in growing cells: A biophysical primer [PDF]
Cell growth and gene expression, essential elements of all living systems, have long been the focus of biophysical interrogation. Advances in single-cell methods have invigorated theoretical studies into these processes. However, until recently, there was little dialog between the two areas of study.

Possible role of human ribonuclease dicer in the regulation of R loops
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Unsupervised learning of transcriptional regulatory networks via latent tree graphical models [PDF]
Gene expression is a readily-observed quantification of transcriptional activity and cellular state that enables the recovery of the relationships between regulators and their target genes. Reconstructing transcriptional regulatory networks from gene expression data is a problem that has attracted much attention, but previous work often makes the ...

Geometric Characteristics of Dynamic Correlations for Combinatorial Regulation in Gene Expression Noise [PDF]
Knowing which mode of combinatorial regulation (typically, AND or OR logic operation) that a gene employs is important for determining its function in regulatory networks. Here, we introduce a dynamic cross-correlation function between the output of a gene and its upstream regulator concentrations for signatures of combinatorial regulation in gene ...

Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

A dynamical system model for predicting gene expression from the epigenome [PDF]
Gene regulation is an important fundamental biological process. The regulation of gene expression is managed through a variety of methods including epigenetic processes (e.g., DNA methylation). Understanding the role of epigenetic changes in gene expression is a fundamental question of molecular biology.

The aberrant expression pattern and prognostic implications of HIVEP3 in AML were explored and validated based on versatile bioinformatics tools. A LASSO model which combined HIVEP3 with ferroptosis regulators was created to predict the prognosis for AML patients.
