AI Article Synopsis

  • - The study investigates the use of blood-based biomarkers, particularly microRNA-185-5p, to diagnose and treat endometriosis in a minimally invasive way by comparing levels in women with and without the condition.
  • - In a case-control setup, 25 women with severe endometriosis and 25 without were analyzed using high-throughput small RNA sequencing and qRT-PCR, revealing that miR-185-5p was significantly down-regulated in those with endometriosis.
  • - The findings indicate that low levels of miR-185-5p in blood could serve as a valuable non-invasive marker for the early detection of endometriosis, showing a promising area under the ROC curve for diagnosis.

Article Abstract

Background: Using blood-based biomarkers such as microRNAs (miRNAs) may allow particularly effective and minimally invasive diagnosis and treatment of endometriosis. We evaluated the differential expression of circulating miRNA-185-5p (miR-185-5p), vascular endothelial growth factor , and platelet-derived growth factor target genes between endometriosis and healthy women.

Materials And Methods: 25 women with a history of endometriosis (grad III-IV) diagnosed by laparoscopy as the case group and 25 women without endometriosis underwent laparoscopy for ovarian cysts or pelvic pain as the control group were enrolled in this case-control study. Blood samples were obtained, and total RNA was used for high-throughput small RNA sequencing, and this was confirmed by means of quantitative real-time polymerase chain reaction (qRT-PCR).

Results: miRNA expression profiling using non-coding RNA sequencing revealed that one miRNA including miR-185-5p was significantly down-regulated in the case group compared with the controls. The qRT-PCR results showed significant downregulation of the expression level of miR-185-5p ( 0.01) in the plasma of the case group. Receiver operating characteristic (ROC) curve analysis showed the area of miR-185-5p under the ROC curve for endometriosis diagnosis was 0.919 ( 0.001). The RT-PCR results demonstrated that there was no significant difference in the expression of and mRNA of blood samples in the cases compared to the control group (, = 0.09 and , = 0.36).

Conclusion: The low expression of miR-185-5p in the plasma of women with endometriosis could be employed as an important non-invasive biomarker for early detection and screening of endometriosis by blood samples.

Defining the cellular factors that drive growth rate and proteome composition is essential for understanding and manipulating cellular systems. In bacteria, ribosome concentration is known to be a constraining factor of cell growth rate, while gene concentration is usually assumed not to be limiting. Here, using single-molecule tracking, quantitative single-cell microscopy, and modeling, we show that genome dilution in cells arrested for DNA replication limits total RNA polymerase activity within physiological cell sizes across tested nutrient conditions.

HER-2 SMASH.

Purpose: Human epidermal growth factor-2 (HER-2) targeted drugs are used in only HER-2 overexpressed cancers. However, only a small portion of these cancer types are HER-2 overexpressed. In this study, we aimed to upregulate HER-2 receptors in MCF-7 breast cancer and HT-29 colon cancer cell cultures, which these cells are not HER-2 upregulated in natural status.

Primary cilia as antennas for oxygen.

Over the last few decades, the primary cilium, an inconspicuous cell organelle, has increasingly become the focus of current research. The primary cilium is a microtubule-based, non-motile, antenna-like structure that is present on almost all mammalian cells. The ciliary membrane incorporates a large number of receptor molecules, which further characterize this cellular organelle.

A major challenge in the stem cell biology field is the ability to produce fully functional cells from induced pluripotent stem cells (iPSCs) that are a valuable resource for cell therapy, drug screening, and disease modelling. Here, we developed a novel inducible CRISPR-mediated activation strategy (iCRISPRa) to drive the expression of multiple endogenous transcription factors (TFs) important for in vitro cell fate and differentiation of iPSCs to haematopoietic progenitor cells. This work has identified a key role for IGFBP2 in developing haematopoietic progenitors.

Frailty Is Strongest Need Factor among Predictors of Prehabilitation Utilization for Total Hip or Knee Arthroplasty in Fee-for-Service Medicare Beneficiaries.

Objective: Prehabilitation may have benefits for total hip arthroplasty (THA) and total knee arthroplasty (TKA), given an aging population with multimorbidity and the growth of value-based programs that focus on reducing postoperative costs. We aimed to describe prehabilitation use and examine predictors of utilization in fee-for-service Medicare beneficiaries.

Methods: This retrospective cohort study using the Medicare Limited Data Set included fee-for-service Medicare beneficiaries who were ≥ 66 years old and who underwent inpatient elective THA or TKA between January 1, 2016, and September 30, 2021.
