Background & Aims: Risankizumab is a selective interleukin-23 inhibitor approved for the treatment of Crohn's disease (CD). We report a large long-term real-world experience with risankizumab in CD.

Methods: We performed a prospective monitoring of clinical outcomes in patients at a large tertiary center who started treatment with risankizumab.

Article Synopsis
  • - The proteasome, critical in degrading unwanted proteins, shifts between the nucleus and cytoplasm depending on amino acid availability, particularly under starvation conditions, which affects protein synthesis.
  • - The presence of three aromatic amino acids (Tyr, Trp, Phe) can inhibit the proteasome's movement to the cytoplasm and trigger cell death, while their higher concentrations in healthy cells can disrupt key stress signaling pathways.
  • - Using the aromatic amino acids has shown potential for cancer therapy by sequestering the proteasome in the nucleus, inhibiting tumor growth, and altering various cell processes related to proliferation and death, suggesting Sestrin3's significant role in this mechanism.

: Sarcopenia is underdiagnosed in patients with inflammatory bowel disease (IBD). Low alanine transaminase (ALT) is associated with sarcopenia. We evaluated the association between low ALT and the presence of IBD and disease activity.

L23 is a recognized cytokine involved in the pathogenesis of inflammatory bowel diseases (IBDs). The first IL23-targeting agent that became available for clinical use in IBD was Ustekinumab, a monoclonal antibody that targets p40, a shared subunit of both IL23 and IL12. Risankizumab (Skyrizi; Abbvie) is a humanized IgG1 monoclonal antibody which binds to the p19 subunit and therefore selectively inhibits IL23.

Background: Women with inflammatory bowel diseases (IBD) often receive biologics to maintain remission during pregnancy.

Aims: To assess maternal and neonatal outcomes in patients with IBD treated with ustekinumab (UST) during pregnancy METHODS: In a multicentre, prospective cohort study, we recruited women with IBD treated with UST during pregnancy between 2019 and 2021. Outcomes were compared among patients treated with UST, anti-tumour necrosis factor α, (anti-TNF) and non-UST, non-anti-TNF therapies.

Background: Crohn's disease (CD) and ulcerative colitis (UC) are chronic, immune-mediated inflammatory bowel diseases (IBD) affecting millions of people worldwide. IBD therapies, designed for continuous immune suppression, often render patients more susceptible to infections. The effect of the immune suppression on the risk of coronavirus disease-19 (COVID-19) is not fully determined yet.

Somatic mutations in p53, which inactivate the tumour-suppressor function of p53 and often confer oncogenic gain-of-function properties, are very common in cancer. Here we studied the effects of hotspot gain-of-function mutations in Trp53 (the gene that encodes p53 in mice) in mouse models of WNT-driven intestinal cancer caused by Csnk1a1 deletion or Apc mutation. Cancer in these models is known to be facilitated by loss of p53.

Genetic aberrations in the toll-like receptor (TLR)3 pathway are associated with increased susceptibility to herpes simplex virus (HSV) infections. Leucine-rich repeat and PYD-containing protein (NLRP)12 is a component of the inflammasome apparatus, which is critical to an immediate innate inflammatory response. Aberrations in NLRP12 have been shown to mediate auto-inflammation.

CKIα ablation induces p53 activation, and CKIα degradation underlies the therapeutic effect of lenalidomide in a pre-leukemia syndrome. Here we describe the development of CKIα inhibitors, which co-target the transcriptional kinases CDK7 and CDK9, thereby augmenting CKIα-induced p53 activation and its anti-leukemic activity. Oncogene-driving super-enhancers (SEs) are highly sensitive to CDK7/9 inhibition.

Aging and cancer are highly correlated biological phenomena. Various cellular processes such as DNA damage responses and cellular senescence that serve as tumor suppressing mechanisms throughout life result in degenerative changes and contribute to the aging phenotype. In turn, aging is considered a pro-tumorigenic state, and constitutes the single most important risk factor for cancer development.

Context: Type 2 Wolfram syndrome (T2-WFS) is a neuronal and β-cell degenerative disorder caused by mutations in the CISD2 gene. The mechanisms underlying β-cell dysfunction in T2-WFS are not known, and treatments that effectively improve diabetes in this context are lacking.

Objective: Unraveling the mechanisms of β-cell dysfunction in T2-WFS and the effects of treatment with GLP-1 receptor agonist (GLP-1-RA).

Background: Chronic inflammation has been recognized as one of the hallmarks of cancer. We recently showed that parainflammation, a unique variant of inflammation between homeostasis and chronic inflammation, strongly promotes mouse gut tumorigenesis upon p53 loss. Here we explore the prevalence of parainflammation in human cancer and determine its relationship to certain molecular and clinical parameters affecting treatment and prognosis.

Inflammation is emerging as one of the hallmarks of cancer, yet its role in most tumors remains unclear. Whereas a minority of solid tumors are associated with overt inflammation, long-term treatment with non-steroidal anti-inflammatory drugs is remarkably effective in reducing cancer rate and death. This indicates that inflammation might have many as-yet-unrecognized facets, among which an indolent course might be far more prevalent than previously appreciated.

Type 2 diabetes mellitus is very prevalent among persons aged 60-80 years old. This population is expected to increase in number and is characterized by the presence of comorbidities, long standing diabetes, frailty, high rate of cognitive impairment and limited life expectancy. These characteristics have a significant impact on diabetes and treatment among the elderly, much as diabetes predisposes to these conditions.

The β-cell replacement by islet transplantation is an attractive approach for normalizing blood glucose without hypoglycaemia in patient with type 1 diabetes mellitus (T1D). A pioneer study by the Edmonton group more than a decade ago showed that alloislet transplantation may result in insulin independence for at least 1 year after transplantation. This breakthrough excited researchers, physicians and patients, who felt that the ultimate goal of cure for T1D was at hand.
