Subcutaneous infliximab CT-P13 without intravenous induction in psoriatic arthritis: A case report and pharmacokinetic considerations.

Introduction: The biosimilar CT-P13, the first and only subcutaneous (SC) infliximab formulation, is recommended for patients with psoriatic arthritis (PsA) and can be administered as a maintenance treatment, to be started 4 weeks after the induction treatment with 2 intravenous (IV) infliximab infusions.

Objective: To evaluate treatment with SC infliximab without prior IV infusion induction to meet patient needs.

Materials And Methods: After approval by the ethics review board and based on the schedule approved for rheumatoid arthritis, SC induction was performed with infliximab CT-P13 120 mg weekly for 4 weeks, followed by an injection of 120 mg every 2 weeks.

NRF2 connects Src tyrosine kinase to ferroptosis resistance in glioblastoma.

Glioblastoma is a severe brain tumor characterized by an extremely poor survival rate of patients. Glioblastoma cancer cells escape to standard therapeutic protocols consisting of a combination of ionizing radiation and temozolomide alkylating drugs that trigger DNA damage by rewiring of signaling pathways. In recent years, the up-regulation of factors that counteract ferroptosis has been highlighted as a major driver of cancer resistance to ionizing radiation, although the molecular connection between the activation of oncogenic signaling and the modulation of ferroptosis has not been clarified yet.

Abl depletion via autophagy mediates the beneficial effects of quercetin against Alzheimer pathology across species.

Alzheimer's disease is the most common age-associated neurodegenerative disorder and the most frequent form of dementia in our society. Aging is a complex biological process concurrently shaped by genetic, dietary and environmental factors and natural compounds are emerging for their beneficial effects against age-related disorders. Besides their antioxidant activity often described in simple model organisms, the molecular mechanisms underlying the beneficial effects of different dietary compounds remain however largely unknown.

Identification and Biological Characterization of the Pyrazolo[3,4-]pyrimidine Derivative SI388 Active as Src Inhibitor.

Src is a non-receptor tyrosine kinase (TK) whose involvement in cancer, including glioblastoma (GBM), has been extensively demonstrated. In this context, we started from our library of pyrazolo[3,4-]pyrimidines that are active as Src and/or Bcr-Abl TK inhibitors and performed a lead optimization study to discover a new generation derivative that is suitable for Src kinase targeting. We synthesized a library of 19 compounds, .

Caspase-8 and Tyrosine Kinases: A Dangerous Liaison in Cancer.

Caspase-8 is a cysteine-aspartic acid protease that has been identified as an initiator caspase that plays an essential role in the extrinsic apoptotic pathway. Evasion of apoptosis is a hallmark of cancer and Caspase-8 expression is silenced in some tumors, consistent with its central role in apoptosis. However, in the past years, several studies reported an increased expression of Caspase-8 levels in many tumors and consistently identified novel "non-canonical" non-apoptotic functions of Caspase-8 that overall promote cancer progression and sustain therapy resistance.
