Attitudes of cancer patients toward ctDNA‐based liquid biopsy for follow‐up

open access: yesMolecular Oncology, EarlyView.
This mixed‐methods study explored cancer patients' experiences, knowledge, and preferences regarding ctDNA‐based liquid biopsy for follow‐up. Awareness of ctDNA was low and recall of previous liquid biopsy was imperfect, yet acceptance was high.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Induction of somatic embryos in cultures of Asparagus racemosus Willd: an endangered medicinally important plant

open access: yesBulletin of the National Research Centre, 2019
Background Somatic embryogenesis is one of the most popular in vitro regeneration methods for mass micropropagation. In the present study, somatic embryogenesis via zygotic embryos was studied in Asparagus racemosus Willd.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

open access: yesFEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Improvement of soybean somatic embryo development and maturation by abscisic acid treatment

open access: yes, 2000
Recovery of tissue culture-derived plants through somatic embryogenesis is a useful system for genetic engineering of soybean. The effect of abscisic acid (ABA) on soybean somatic embryogenesis, development, and maturation was investigated. ABA at 1, 10,

Comparative Analysis of Nuclear Transfer Embryo Derived Mouse Embryonic Stem Cells. Part II: Gene regulation [PDF]

open access: yes, 2012
In a mouse model nuclear transfer embryo-derived embryonic stem cell lines (ntESCs) of various genetic backgrounds and donor cell types were compared with reference ESCs and analyzed comprehensively at molecular level as a second part of a larger study ...

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

open access: yesFEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Somatic embryo germination and plant regeneration of three grapevine cvs: Effect of IAA, GA3 and embryo morphology [PDF]

open access: yes, 2006
Plant regeneration was achieved using somatic embryos obtained from the Vitis vinifera cvs Sugraone, Crimson Seedless and Don Mariano. White somatic embryos, 1.5-3 mm in length, were cultured on embryo germination medium with or without IAA (10 μM) + GA3

Epidermal Cell Wall Biogenesis with Emphasis on Cuticular Layer Formation during Direct Somatic Embryogenesis in Rice

open access: yesPlant Production Science, 1999
Epidermal cell wall biogenesis with emphasis on cuticular layer formation during direct somatic embryogenesis in rice was examined by transmission electron microscopy. The first phenomenon noticed in the early globular stage of somatic embryos was a high
