Mitochondrial energy metabolism in baby hamster kidney (BHK-21/C13) cells treated with karnozin extra®

Int. j. morphol; 40 (1), 2022
SUMMARY: Carnosine is known as a natural dipeptide, which inhibits the proliferation of tumor cells throughout its action on mitochondrial respiration and cell glycolysis. However, not much is known about its effects on the metabolism of healthy cells. We explored the effects of Karnozin EXTRA® capsule ...

A comprehensive morphometric study of visceral and subcutaneous adipose tissue depots in mice, hamsters and rats

Int. j. morphol; 40 (5), 2022
SUMMARY: Adipose tissue morphology of different fat tissue depots can be described using the number of adipocytes and cell surface of adipocytes. This study deals with characteristics and morphometric analysis of white and brown adipose tissue depots in healthy adult laboratory mice, hamsters and rats of...

Knockout of caspase-7 gene improves the expression of recombinant protein in CHO cell line through the cell cycle arrest in G2/M phase

Biol. Res; 55 (), 2022
BACKGROUND: Chinese hamster ovary cell line has been used routinely as a bioproduction factory of numerous biopharmaceuticals. So far, various engineering strategies have been recruited to improve the production efficiency of this cell line such as apoptosis engineering. Previously, it is reported that t...

Identification and sequence analysis of prolactin receptor and its differential expression profile at various developmental stages in striped hamsters

Braz. j. med. biol. res; 54 (5), 2021
Prolactin (PRL) plays critical roles in regulation of biological functions with the binding of specific prolactin receptor (PRLR). Revealing the expression patterns of PRLR at different developmental stages is beneficial to better understand the role of PRL and its mechanism of action in striped hamsters...

Effect of topical 2% eucalyptus extract on 5-fu-induced oral mucositis in male golden hamsters

Braz. dent. j; 31 (3), 2020
Abstract Oral mucositis is a common inflammatory complication among patients with cancer. This study evaluated the histopathological, stereological, and antioxidant markers of 2% eucalyptus extract in induced oral mucositis in male golden hamsters. In this animal study, oral mucositis was induced in 30 m...

Investigating associations between intestinal alterations and parasite load according to Bifidobacterium spp. and Lactobacillus spp. abundance in the gut microbiota of hamsters infected by Leishmania infantum

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Visceral leishmaniasis (VL) is a tropical neglected disease with high associated rates of mortality. Several studies have highlighted the importance of the intestinal tract (IT) and gut microbiota (GM) in the host immunological defense. Data in the literature on parasite life cycle and host i...

Caspase-7 deficiency in Chinese hamster ovary cells reduces cell proliferation and viability

Biol. Res; 53 (), 2020
BACKGROUND: Chinese hamster ovary (CHO) cells are the most commonly used mammalian host cell In the commercial-scale production of biopharmaceutical proteins. Modification of genes involved in apoptosis may improve the productivity of CHO cells. Executive caspases, including caspases 3 and 7, play critic...

DNA nanovaccines prepared using LemA antigen protect Golden Syrian hamsters against Leptospira lethal infection

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Nanoparticles (NPs) are viable candidates as carriers of exogenous materials into cells via transfection and can be used in the DNA vaccination strategy against leptospirosis. OBJECTIVES We evaluated the efficiency of halloysite clay nanotubes (HNTs) and amine-functionalised multi-walled ca...

Oxyurid nematodes of pet rodents in Slovakia - a neglected zoonotic threat

Abstract The role of rodents as reservoirs of helminths of public health importance is not well known. The zoonotic potential of Syphacia spp. has been confirmed; therefore, the study aimed to estimate the occurrence of oxyurid nematodes in small rodents from pet shops and breeding clubs in Slovakia. Fec...

Comparative assessment of the replication efficiency of dengue, yellow fever, and chikungunya arboviruses in some insect and mammalian cell lines

Abstract INTRODUCTION: Insect cell cultures play an essential role in understanding arboviral replication. However, the replicative efficiency of some of these viruses such as dengue (DENV), yellow fever (YFV), and chikungunya (CHIKV) in a new cellular substrate (Lulo) and in the other two recognized ce...
