Abstract
Endometrial (EC) and cervical (CC) cancers are the most prevalent malignancies of the female reproductive system. There is a global trend towards increasing incidence and mortality, with a decreasing age trend. E3 ligases label substrates with ubiquitin to regulate their activity and stability and are involved in various cellular functions. Studies have confirmed abnormal expression or mutations of E3 ligases in EC and CC, indicating their vital roles in the occurrence and progression of EC and CC. This paper provides an overview of the E3 ligases implicated in EC and CC and discusses their underlying mechanism. In addition, this review provides research advances in the target of ubiquitination processes in EC and CC.

Chiboub O, Capote-Yanes E, Sifaoui I, Reyes-Batlle M, Rodríguez-Expósito RL, Piñero JE, Lorenzo-Morales J. In vitro validation of the amoebicidal activity of commercial eye drops as second activity. INTERNATIONAL JOURNAL FOR PARASITOLOGY-DRUGS AND DRUG RESISTANCE 2021; 15:144-151. [PMID: 33684885 PMCID: PMC7940700 DOI: 10.1016/j.ijpddr.2021.02.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 02/25/2021] [Accepted: 02/25/2021] [Indexed: 11/28/2022]
Abstract
The validation of anti-Acanthamoeba activity of commercial eye drops has gained a great interest recently and a growing number of commercials eye drop were evaluated for their aptitude to inhibit Acanthamoeba as a second pharmacological effect. In the present study, three different eye drops, commercializing in Spain, including TobraDex, Cusimolol and Colircusi antiedema have been tested in vitro against trophozoites and cysts stage of the facultative pathogen Acanthamoeba. The alamarBlue™ method was used to evaluate both trophocidal and cysticidal properties. The most active eye drops were tested for their impact on some programmed cell death features. We found out that the cells inhibition was strain and eye drop dependent, and 5% eye drop was able to eliminate both trophozoite and cyst stage of Acanthamoeba spp. A treatment of 24 h with 5% of TobraDex or Cusimolol was able to show DNA condensation, collapse in the mitochondrial membrane potential and reduction of the ATP level production in Acanthamoeba. We could assume that the present eye drops could induce programed cell death like process in Acanthamoeba via mitochondrial pathway.

The E3 ligase HUWE1 mediates TGFBR2 ubiquitination and promotes gastric cancer cell proliferation, migration, and invasion. Invest New Drugs 2021; 39:713-723. [PMID: 33405091 DOI: 10.1007/s10637-020-01041-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 11/25/2020] [Indexed: 12/25/2022]
Abstract
HUWE1, as a well-known E3 ligase, has an oncogenic or tumor-suppressive role in various cancers by mediating ubiquitination and degradation of substrates. However, the role and action mechanism of HUWE1 in gastric cancer (GC) remain unclear. This study aimed to investigate whether HUWE1 plays a role in GC development in vitro by mediating transforming growth factor-β receptor 2 (TGFBR2) ubiquitination and degradation. HUWE1 was overexpressed in SGCA-7901 GC cells and silenced in MGC-803 GC cells. Then, GC cell proliferation, migration, and invasion were evaluated by MTT assay and Transwell migration and invasion assay, respectively. The regulatory effect and mechanism of HUWE1 on TGFBR2 expression were assessed by qRT-PCR, western blot, and ubiquitination assay. HUWE1 mRNA and protein levels were higher in human GC tissues than in matched noncancerous gastric tissues. HUWE1 overexpression promoted, whereas HUWE1 silencing inhibited GC cell proliferation, migration, and invasion. HUWE1 promoted ubiquitination and degradation of TGFBR2. TGFBR2 overexpression impaired the tumor-promoting effect of HUWE1 overexpression in regulating GC cell behaviors. HUWE1 promoted GC cell proliferation, migration, and invasion, at least partially, by mediating TGFBR2 ubiquitination. Our data indicated a novel regulatory mechanism of HUWE1 in GC development, and provided a potential idea for the disease treatment.
