RNA modulators of complex phenotypes in mammalian cells. [PDF]
RNA-mediated gene silencing, in the form of RNA interference (RNAi) or microRNAs (miRNAs) has provided novel tools for gene discovery and validation in mammalian cells.

Selection of chromosomal DNA libraries using a multiplex CRISPR system. [PDF]
The directed evolution of biomolecules to improve or change their activity is central to many engineering and synthetic biology efforts. However, selecting improved variants from gene libraries in living cells requires plasmid expression systems that ...

The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

Conversion of cDNA differential display results (DDRT-PCR) into quantitative transcription profiles [PDF]
Background: Gene expression studies on non-model organisms require open-end strategies for transcription profiling. Gel-based analysis of cDNA fragments allows to detect alterations in gene expression for genes which have neither been sequenced yet nor are available in cDNA libraries. Commonly used protocols are cDNA Differential Display (DDRT-PCR) and

SpZ12-1, a negative regulator required for spatial control of the territory-specific CyIIIa gene in the sea urchin embryo [PDF]
The CyIIIa cytoskeletal actin gene of the sea urchin Strongylocentrotus purpuratus is activated in late cleavage and expressed exclusively in the aboral ectoderm territory of the embryo.

The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Construction of Gene Targeting Vectors from λKOS Genomic Libraries
We describe a highly redundant murine genomic library in a new λ phage, λ knockout shuttle (λKOS) that facilitates the very rapid construction of replacement-type gene targeting vectors.

Representative cDNA Libraries and Their Utility in Gene Expression Profiling [PDF]
An increasing interest in gene expression profiles in human diseases has led to the use of microdissected tumors and biopsies in gene discovery approaches. Since many of these clinical samples yield extremely small amounts of RNA, reproducible methods are needed to amplify this RNA while maintaining the original message profile.

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Estimating the Number of Essential Genes in Random Transposon Mutagenesis Libraries [PDF]
Biologists use random transposon mutagenesis to construct knockout libraries for bacteria. Random mutagenesis offers cost and efficiency benefits over the standard site directed mutagenesis, but one can no longer ensure that all the nonessential genes will appear in the library.
