SIK2 and SIK3 Differentially Regulate Mouse Granulosa Cell Response to Exogenous Gonadotropins In Vivo.

Salt-inducible kinases (SIKs), a family of serine/threonine kinases, were found to be critical determinants of female fertility. SIK2 silencing results in increased ovulatory response to gonadotropins. In contrast, SIK3 knockout results in infertility, gonadotropin insensitivity, and ovaries devoid of antral and preovulatory follicles.

Trends in colorectal cancer surgical resection rates during the screening era: a retrospective study in Italy.

Background: Faecal immunochemical test (FIT)-based screening is effective in reducing colorectal cancer (CRC) incidence, but its sensitivity for proximal lesions remains low.

Objectives: We compared age-adjusted CRC surgical resection rates across anatomic sites (proximal colon, distal colon, rectum), age groups and sex over 20 years in a large Italian population. We particularly focused on changes in trends following FIT-screening implementation in the target population (50-69 years).

Cancer incidence in immigrants by geographical area of origin: data from the Veneto Tumour Registry, Northeastern Italy.

Objective: We investigated whether there are differences in cancer incidence by geographical area of origin in North-eastern Italy.

Methods: We selected all incident cases recorded in the Veneto Tumour Registry in the period 2015-2019. Subjects were classified, based on the country of birth, in six geographical areas of origin (Italy, Highly Developed Countries-HDC, Eastern Europe, Asia, Africa, South-central America).

Sexual violence against children and adolescents in Paraná State: geospatial analysis and main socioeconomic indicators.

Objective: Child sexual violence is a multidimensional problem of many contemporary societies, affecting people of all sexes, social stratum and age groups. Offenses involving children and adolescents are more serious, given their total or partial dependence on parents and caregivers. Information on child sexual violence in Brazil is found in raw form and without detail.

Molecular crosstalk between insulin-like growth factors and follicle-stimulating hormone in the regulation of granulosa cell function.

Background: The last phase of folliculogenesis is driven by follicle-stimulating hormone (FSH) and locally produced insulin-like growth factors (IGFs), both essential for forming preovulatory follicles.

Methods: This review discusses the molecular crosstalk of the FSH and IGF signaling pathways in regulating follicular granulosa cells (GCs) during the antral-to-preovulatory phase.

Main Findings: IGFs were considered co-gonadotropins since they amplify FSH actions in GCs.
