Therapeutic vulnerability to PARP1,2 inhibition in RB1-mutant osteosarcoma [PDF]

open access: yes, 2021
Loss-of-function mutations in the RB1 tumour suppressor are key drivers in cancer, including osteosarcoma. RB1 loss-of-function compromises genome-maintenance and hence could yield vulnerability to therapeutics targeting such processes.

Ginsenoside CK, rather than Rb1, possesses potential chemopreventive activities in human gastric cancer via regulating PI3K/AKT/NF-κB signal pathway

open access: yesFrontiers in Pharmacology, 2022
Ginsenoside Rb1, a main component of ginseng, is often transformed into ginsenoside CK by intestinal flora to exert various pharmacological activity. However, it remains unclear whether ginsenoside CK is responsible for the anti-gastric cancer effect of ...

Effects of berberine (BBR) to inhibit the degradation of RB1 mRNA with poly(A) (RB1-pro-RB1) or without poly(A) (RB1-pro-RB1-Δpoly A-).

open access: yes, 2014
(A) Cartoon of the plasmid models used in this study. Polyadenylation signals were showed in red. (B) Expressions of GFP in cells with transfection of RB1-promoter-RB1-GFP with and without poly(A) plasmids detected using Western blot.

RB1‑promoter methylation in glioblastoma: A rare event in glioblastoma [PDF]

open access: yes, 2023
The retinoblastoma gene (RB1) is a tumor suppressor gene that serves a key role in the development of numerous tumor diseases that can be downregulated by DNA methylation within its promoter region.

Promoter Hypermethylation of the RB1 Gene in Glioblastomas [PDF]

open access: yesLaboratory Investigation, 2001
Loss of expression of the retinoblastoma gene (RB1) has been shown to occur in up to 25% of glioblastomas (WHO Grade IV). To elucidate the underlying mechanism, we assessed RB1 promoter hypermethylation using methylation-specific polymerase chain reaction and RB1 expression by immunohistochemistry in 35 primary (de novo) glioblastomas and in 21 ...

Ginsenoside Rb1 Induces Beta 3 Adrenergic Receptor–Dependent Lipolysis and Thermogenesis in 3T3-L1 Adipocytes and db/db Mice

open access: yesFrontiers in Pharmacology, 2019
Obesity is constantly rising into a major health threat worldwide. Activation of brown-like transdifferentiation of white adipocytes (browning) has been proposed as a promising molecular target for obesity treatment.

Melanocyte homeostasis in vivo tolerates Rb1 loss in a developmentally independent fashion

open access: yes, 2010
There has been uncertainty regarding the precise role that the pocket protein Rb1 plays in murine melanocyte\ud homeostasis. It has been reported that the TAT-Cre mediated loss of exon 19 from a floxed Rb1 allele causes\ud melanocyte apoptosis in vivo ...

Progression of Low-Grade Neuroendocrine Tumors (NET) to High-Grade Neoplasms Harboring the NEC-Like Co-alteration of RB1 and TP53

open access: yesEndocrine pathology
High-grade or grade 3 epithelial neuroendocrine neoplasms (G3 NEN) are now divided into grade 3 well-differentiated neuroendocrine tumor (G3 NET) and neuroendocrine carcinoma (NEC), both defined by Ki-67 > 20% and/or > 20 mitoses per 2 mm2.

RB1 gene mutations in retinoblastoma [PDF]

open access: yesHuman Mutation, 1999
Mutations in both alleles of the RB1 gene are causal for the development of retinoblastoma, a childhood tumor of the eye. The spectrum of somatic and germline mutations in this gene is dominated by small mutations. Data on small mutations are listed in a locus specific database available at http://www.d-lohmann.de/Rb/mutations.html.

Genetic detection of bladder cancer by microsatellite analysis of p16, RB1 and p53 tumor suppressor genes

open access: yes, 2001
Purpose: We investigated the incidence of genetic alterations in urine specimens from patients with bladder cancer. Materials and Methods: A total of 28 cytological urine specimens were assessed for microsatellite alternations, and 15 microsatellite ...
