The interplay of the translocase activity and protein recruitment function of PICH in ultrafine anaphase bridge resolution and genomic stability.

Incomplete sister centromere decatenation results in centromeric ultrafine anaphase bridges (UFBs). PICH (PLK1-interacting checkpoint helicase), a DNA translocase, plays a crucial role in UFB resolution by recruiting UFB-binding proteins and stimulating topoisomerase IIα. However, the involvement of distinct PICH functions in UFB resolution remains ambiguous.

FANCM promotes PARP inhibitor resistance by minimizing ssDNA gap formation and counteracting resection inhibition.

Poly(ADP-ribose) polymerase inhibitors (PARPis) exhibit remarkable anticancer activity in tumors with homologous recombination (HR) gene mutations. However, the role of other DNA repair proteins in PARPi-induced lethality remains elusive. Here, we reveal that FANCM promotes PARPi resistance independent of the core Fanconi anemia (FA) complex.

Protocol for biallelic tagging of an endogenous gene using CRISPR-Cas9 in human cells.

We present here a protocol for biallelic tagging of an endogenous gene in human cells using CRISPR-Cas9 editing technology. Using RIF1 as an example, we describe tagging the gene with a mini-auxin-inducible degron and a green fluorescent protein at its C terminus. We detail steps for preparing and designing the sgRNA and homologous repair template, and clone selection and verification.

Human Endonuclease ANKLE1 Localizes at the Midbody and Processes Chromatin Bridges to Prevent DNA Damage and cGAS-STING Activation.

Chromatin bridges connecting the two segregating daughter nuclei arise from chromosome fusion or unresolved interchromosomal linkage. Persistent chromatin bridges are trapped in the cleavage plane, triggering cytokinesis delay. The trapped bridges occasionally break during cytokinesis, inducing DNA damage and chromosomal rearrangements.

Mutation of Enhances Tolerance to Phosphate Starvation in Rice.

() encodes a protein localized to the endoplasmic reticulum (ER) and cell wall. This gene plays a key role in responding to phosphate (Pi) deprivation, especially in remodeling the root system architecture (RSA). An identification and expression analysis of the family in rice () has been previously reported, and , functioning in Pi uptake and translocation, is required for the normal growth and development of rice.

RIF1 suppresses the formation of single-stranded ultrafine anaphase bridges via protein phosphatase 1.

Resolution of ultrafine anaphase bridges (UFBs) must be completed before cytokinesis to ensure sister-chromatid disjunction. RIF1 is involved in UFB resolution by a mechanism that is not yet clear. Here, we show that RIF1 functions in mitosis to inhibit the formation of 53BP1 nuclear bodies and micronuclei.

The association between phenanthrene and nutrients uptake in lotus cultivar 'Zhongguo Hong Beijing'.

It has been well documented that polycyclic aromatic hydrocarbon (PAHs) can be taken up from the environment by the plants and translocated into the shoots. However, the mechanisms underlying this process are poorly understood. Nelumbo nucifera L.

[Topography and mechanical property of goat temporomandibular joint disc cells].

Objective: This study is performed to investigate the cell topographies and biomechanical properties of two different types of temporomandibular joint (TMJ) discs from goats by using JPK Nano Wizard 3 biological atomic force microscopy (AFM). This process provides a guideline for selecting seed cells for TMJ disc tissue engineering.

Methods: TMJ disc cells from primary goats were cultured by monolayer culture method.

Assessing Transcription Regulatory Elements To Evaluate the Expression Status of Missing Protein Genes on Chromosomes 11 and 19.

During an investigation of missing proteins with the RNA-seq data acquired from three liver cancer cell lines, the majority of the missing protein coding genes (MPGs) located at chromosome 11 (chr11) had no corresponding mRNAs, while a high percentage of the MPGs on chr19 were detected at the mRNA level. The phenomenon, which was also observed in more than 40 cell lines, led to an inquiry of causation of the different transcriptional statuses of the MPGs in the two chromosomes. We hypothesized that the special chromatin structure was a key element to regulate MPG transcription.

Insights from ENCODE on Missing Proteins: Why β-Defensin Expression Is Scarcely Detected.

β-Defensins (DEFBs) have a variety of functions. The majority of these proteins were not identified in a recent proteome survey. Neither protein detection nor the analysis of transcriptomic data based on RNA-seq data for three liver cancer cell lines identified any expression products.
