Fusobacterium (F.) nucleatum is a carcinogenesis microbiota in colorectal cancer (CRC). Growing evidence shows that F. contributes to chemoresistance. Ferroptosis reported restore the susceptibility of resistant cells chemotherapy. However, role gut affecting ferroptosis chemoresistance remains unclear. Here, we examined CRC tissues patients using 16S rRNA sequencing investigate possible connection between dysbiosis and relapse CRC. We found high abundance tissue associated with relapse....

Background Thyroid hormone withdrawal (THW) in postoperative thyroid cancer patients who need always accompanied by complications (e.g., dyslipidemia and constipation). At present, there are no effective safe means to alleviate these complications. Purpose We aimed assess the oral-gut microbiota profiles THW then investigate whether probiotics could alleviating related therapeutic effects were associated with state. Methods Fifty eligible carcinoma undergoing thyroidectomy randomly assigned...

A steady-state metaphase spindle maintains constant length, although the microtubules undergo intensive dynamics. Tubulin dimers are incorporated at plus ends of while they removed from minus ends, resulting in poleward movement. Such microtubule flux is regulated by rescue factors CLASPs kinetochores and depolymerizing protein Kif2a poles, along with other regulators How polymerization depolymerization coordinated remains unclear. Here we show that TPX2, a microtubule-bundling activator...

In the current assay, we applied green chemistry to synthesize silver nanoparticles (AgNPs) and incorporated curcumin-mediated AgNPs into polycaprolactone (PCL) nanofibers. The results showed that have a spherical morphology uniform shape with hydrodynamic diameter of around 112.9 nm polydispersity index 0.2. Moreover, zeta potential −3.7 mV. pristine PCL nanofibers 177 ± 37 PCL/AgNPs 163 34 nm. biological assessments (MTT Live/Dead assays) did not induce significant cell toxicity. disk...

KRAS is a potent oncogenic driver which results in downstream hyperactivation of MAPK signaling, while simultaneously increasing replication stress (RS) and accumulation DNA damage. KRASG12C mutations are common targetable alterations. Therapeutic inhibition eventual resistance to these inhibitors also known drive RS damage through adaptive mechanisms that maintain addiction high signaling. High levels result stronger reliance on cell cycle checkpoints, thereby introducing vulnerability...

Protein phosphatases are critical for regulating cell signaling, cycle, and fate decisions, their dysregulation leads to an array of human diseases like cancer. The dual specificity (DUSPs) have emerged as important factors driving tumorigenesis cancer therapy resistance. DUSP12 is a poorly characterized atypical DUSP widely conserved throughout evolution. Although no direct substrate has been firmly established, that implicated in protecting cells from stress, ribosomal biogenesis,...
