It is believed that clonal expansion and cancer growth is the result of the deregulation of proliferation and cell death. Recently, salvador, a molecule that can regulate both cell proliferation and cell death, was identified. It was also reported that human salvador (hWW45) is mutated in some cancer cell lines. However, there have been no data regarding salvador gene mutations in human cancer tissues. To explore the hypothesis that the salvador gene might be similarly mutated in human cancer tissues, we analyzed the entire coding region of the salvador gene for the detection of somatic mutations in a series of human cancer tissues, including carcinomas from stomach, colon, liver and lung. However, using SSCP analysis, no mutation in the coding and splicing regions could be detected in the cancers. The data presented here suggest that salvador is not frequently mutated in human carcinoma tissues and that the mutation might be tumor-type specific.

Stress and telomere length in leukocytes: Investigating the role of GABRA6 gene polymorphism and cortisol.
Psychoneuroendocrinology
January 2025
Department of Experimental Clinical and Health Psychology, Ghent University, Ghent, Belgium. Electronic address:
Telomere length (TL) is considered a biomarker of aging, and short TL in leukocytes is related to age and stress-related health problems. Cumulative lifetime stress exposure has also been associated with shorter TL and age-related health problems, but the mechanisms are not well understood. We tested in 108 individuals whether shorter TL in leukocytes is observed in individuals with the GABRA6 TT genotype, which has been associated with dysregulation of hypothalamic-pituitary-adrenal axis activity (the main biological stress system) compared to the CC genotype.

: Incomptine A () has been reported to have cytotoxic activity in non-Hodgkin lymphoma cancer cell lines and have effects on U-937 cells, including the induction of apoptosis, the production of reactive oxygen species, and the inhibition of glycolytic enzymes. Also, has cytotoxic activity in the triple-negative subtypes, HER2+, and luminal A of breast cancer cells, with its properties being associated with an effect on the antiapoptotic function of Hexokinase II (HKII). : In this research, we reviewed the altered levels of proteins present in the lymph nodes of male Balb/c mice inoculated with U-937 cells and treated with or methotrexate, as well as mice only inoculated with cancer cells.

Background/objectives: Internalizing disorders, including depression and anxiety, are major contributors to the global burden of disease. While the genetic architecture of these disorders in adults has been extensively studied, their early-life genetic mechanisms remain underexplored, especially in non-European populations. This study investigated the genetic mechanisms underlying internalizing symptoms in a cohort of Latin American children.

Sarcoptic mange has been described in domestic South American camelids (SACs), exported to non-Andean countries, and in wild SAC in their natural habitat. Reports on the incidence of this infestation in llamas or alpacas raised in their original location, on the other hand, are missing. The present study aimed to detect and characterize cases of sarcoptic mange in herds of llamas (Lama glama) raised in the high plateau region (Puna) of the province of Jujuy, Argentina.

Childhood obesity increases the risk of developing metabolic diseases in adulthood, since environmental stimuli during critical windows of development can impact on adult metabolic health. Studies demonstrating the effect of prepubertal diet on adult metabolic disease risk are still limited. We hypothesized that a prepubertal control diet (CD) protects the adult metabolic phenotype from diet-induced obesity (DIO), while a high-fat diet (HFD) would predispose to adult metabolic alterations.
