Novel repurposing of sulfasalazine for the treatment of adrenocortical carcinomas, probably through the SLC7A11/xCT-hsa-miR-92a-3p-OIP5-AS1 network pathway.

Background: Recent multigenomic analysis of adrenocortical carcinomas (ACCs) identified SLC7A11/xCT as a novel biomarker. The Food and Drug Administration-approved anti-inflammatory drug, sulfasalazine (SAS), induces ferroptosis by blocking SLC7A11 expression. We hypothesize that SAS could be repurposed to target ACC cells.

Dlk1 is a novel adrenocortical stem/progenitor cell marker that predicts malignancy in adrenocortical carcinoma.

Disruption of processes involved in tissue development and homeostatic self-renewal is increasingly implicated in cancer initiation, progression, and recurrence. The adrenal cortex is a dynamic tissue that undergoes life-long turnover. Here, using genetic fate mapping and murine adrenocortical carcinoma (ACC) models, we have identified a population of adrenocortical stem cells that express delta-like non-canonical Notch ligand 1 (DLK1).

A Database Tool Integrating Genomic and Pharmacologic Data from Adrenocortical Carcinoma Cell Lines, PDX, and Patient Samples.

Unlabelled: Adrenocortical carcinoma (ACC) is a rare and highly heterogeneous disease with a notably poor prognosis due to significant challenges in diagnosis and treatment. Emphasizing on the importance of precision medicine, there is an increasing need for comprehensive genomic resources alongside well-developed experimental models to devise personalized therapeutic strategies. We present ACC_CellMinerCDB, a substantive genomic and drug sensitivity database (available at https://discover.

ADRENOCORTICAL CARCINOMA: AN ORPHAN MALIGNANCY: FROM THE PATIENT TO THE BENCH AND BACK.

Adrenocortical carcinoma (ACC) is an orphan cancer with 35% five-year survival that has been unchanged for last five decades. Patients often present with severe hypercortisolism or with mass effects. The only Food and Drug Administration (FDA)-approved drug for ACC is mitotane, an insecticide derivative, which provides only limited additional months of survival, but with toxicities.

A Rare Cyclic Cushing Syndrome Mystery Illustrates Diagnostic Principles.

Pheochromocytomas predominantly produce catecholamines, and rarely also produce ACTH, causing Cushing syndrome (CS). Cyclic CS, an uncommon presentation of hypercortisolism, poses a diagnostic challenge. We report a 71-year-old woman who developed cyclic ectopic ACTH secretion from a pheochromocytoma.

E-cadherin expression and gene expression profiles in corticotroph pituitary neuroendocrine tumor subtypes.

Corticotroph adenomas/pituitary neuroendocrine tumors (PitNETs) are associated with significant morbidity and mortality. Predictors of tumor behavior have not shown high prognostic accuracy. For somatotroph adenomas/PitNETs, E-cadherin expression correlates strongly with prognosis.

The association of gender-affirming hormone therapy duration and body mass index on bone mineral density in gender diverse adults.

Introduction: Feminizing and masculinizing gender-affirming hormone therapy (fGAHT, mGAHT) results in bone mineral density (BMD) maintenance or improvement over time in transgender and gender diverse (TGD) adults. Mostly European TGD studies have explored GAHT's impact on BMD, but the association of BMI and BMD in TGD adults deserves further study.

Objective: To determine whether GAHT duration or BMI are associated with BMD and Z-scores among TGD young adults.

Effects of follicle-stimulating hormone on energy balance and tissue metabolic health after loss of ovarian function.

Loss of ovarian function imparts increased susceptibility to obesity and metabolic disease. These effects are largely attributed to decreased estradiol (E), but the role of increased follicle-stimulating hormone (FSH) in modulating energy balance has not been fully investigated. Previous work that blocked FSH binding to its receptor in mice suggested this hormone may play a part in modulating body weight and energy expenditure after ovariectomy (OVX).

PLK1 inhibitors as a new targeted treatment for adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is an aggressive malignancy with limited treatment options. Polo-like kinase 1 (PLK1) is a promising drug target; PLK1 inhibitors (PLK1i) have been investigated in solid cancers and are more effective in TP53-mutated cases. We evaluated PLK1 expression in ACC samples and the efficacy of two PLK1i in ACC cell lines with different genetic backgrounds.

Dual Aldosterone- and Cortisol-Secreting Adrenal Cortical Carcinoma: Pre- and Perioperative Evaluation and Management.

Adrenal cortical carcinoma (ACC) is a rare cancer (1-2/million) that presents with hormone overproduction in 60% of cases. Presentation of ACC with multiple hormone syndromes from different adrenal zones is rare. We present a case of dual-secreting ACC with hyperaldosteronism and cortisol excess.

Short term effects of intraarticular triamcinolone acetonide injection on serum testosterone, luteinizing hormone, and follicle stimulating hormone levels in male veterans: A prospective pilot study.

Background: Despite the common practice of intraarticular corticosteroid injections (ICSIs) for peripheral joint disease, little is known about their systemic effects on the hypothalamic-pituitary-gonadal axis.

Objective: To assess the short-term effects of ICSIs on serum testosterone (T), luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels together with changes in Shoulder Pain and Disability Index (SPADI) scores in a veteran population.

Design: Prospective pilot study.

FSCN1 as a new druggable target in adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with a high risk of relapse and metastatic spread. The actin-bundling protein fascin (FSCN1) is overexpressed in aggressive ACC and represents a reliable prognostic indicator. FSCN1 has been shown to synergize with VAV2, a guanine nucleotide exchange factor for the Rho/Rac GTPase family, to enhance the invasion properties of ACC cancer cells.

Should Dehydroepiandrosterone Be Administered to Women?

Context: Androgen prohormones such as dehydroepiandrosterone (DHEA) increase in early puberty, peak in the second and third decade, and thereafter decline, independent of menopausal status. Investigators have examined their potential beneficial effects in normal women and those with DHEA-deficient states.

Evidence Acquisition: A review of the literature from 1985 to 2021 on the potential benefits and risks of androgen prohormones in women.

Do Women Need Androgens Like a Fish Needs a Bicycle? A Review of the Literature and Clinical Guidelines.

Biopotent androgens such as testosterone circulate in low levels in women. However, androgen precursors, such as dehyroepiandrosterone, are among the most abundant hormones produced in both men and women. While testosterone exerts obvious phenotypic effects in men and is essential for male sexual function, considerable debate and controversy abounds over the role of androgens in women and whether androgens exert an analogous role in women as they do in men.

Mastermind Like Transcriptional Coactivator 3 (MAML3) Drives Neuroendocrine Tumor Progression.

Metastatic disease in pheochromocytomas and paragangliomas (PCC/PGL) is not well-understood. The Cancer Genome Atlas discovered recurrent fusion genes in a subset of tumors that lacked known germline or somatic driver mutations and were associated with aggressive disease. Here, we aimed to investigate the role of MAML3 in tumorigenesis.

Inhibition of Aurora kinase A activity enhances the antitumor response of beta-catenin blockade in human adrenocortical cancer cells.

Adrenocortical cancer (ACC) is a rare and aggressive type of endocrine tumor with high risk of recurrence and metastasis. The overall survival of patients diagnosed with ACC is low and treatment for metastatic stages remain limited to mitotane, which has low efficiency in advanced stages of the disease and is associated with high toxicity. Therefore, identification of new biological targets to improve ACC treatment is crucial.

Advancing Diversity, Equity, and Inclusion in Hospital Medicine.

Background: In nearly all areas of academic medicine, disparities still exist for women and underrepresented minorities (URMs).

Objectives: Develop a strategic plan for advancing diversity, equity, and inclusion (DEI); implement and evaluate the plan, specifically focusing on compensation, recruitment, and policies.

Design, Setting, Participants: Programmatic evaluation conducted in the division of hospital medicine (DHM) at a major academic medical center involving DHM faculty and staff.

Hyperandrogenic Anovulation: Differential Diagnosis and Evaluation.

Hyperandrogenic anovulation refers to the constellation of disorders that present in women with irregular menses, hirsutism and/or acne across the lifespan. Understanding the clinical signs and symptoms of each diagnosis in the differential and laboratory testing to confirm or exclude a diagnosis allows a clinician to appropriately counsel and treat the patient.

A cell-nonautonomous mechanism of yeast chronological aging regulated by caloric restriction and one-carbon metabolism.

Caloric restriction (CR) improves health span and life span of organisms ranging from yeast to mammals. Understanding the mechanisms involved will uncover future interventions for aging-associated diseases. In budding yeast, Saccharomyces cerevisiae, CR is commonly defined by reduced glucose in the growth medium, which extends both replicative and chronological life span (CLS).

Sleep duration and bone health measures in older men.

Unlabelled: The associations between objective measures of sleep duration and bone outcomes in older men are unknown. No consistent, significant association was identified between sleep duration and bone mineral density (BMD) in the current analysis. However, future research should determine if vitamin D status modifies this relationship.
