Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

TP53BP2 Promotes Placental Autophagy and Preeclampsia via G9a and DNMT1 Cooperatively Modulating E2F1

Advanced Science, EarlyView.
G9a, and DNA Methyltransferase1 (DNMT1) cooperatively modulates E2F1 on the promoter of tumor suppressor p53‐binding protein 2 (TP53BP2) increased autophagy in preeclampsia. TP53BP2 promotes autophagy in trophoblasts through DNA methylation and H3K9me2‐mediated transcriptional regulation.

Noonan Syndrome Spectrum Disorders Predispose to Systemic Lupus Erythematosus: Case Report and Critical Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.

Prognostic Value of Lupus Anticoagulant and Anti–β2 Glycoprotein I Antibody in Adverse Pregnancy Outcomes

Arthritis &Rheumatology, EarlyView.
Objective International criteria for antiphospholipid syndrome (APS) include lupus anticoagulant (LA), anticardiolipin (aCL) IgG and IgM, and anti–β2‐glycoprotein I (β2GPI) IgG and IgM. However, evidence supporting their prognostic value or treatment efficacy in improving live birth rates is limited.

Reactive Oxygen Species–Induced Modifications of Fibrin Clots as a Link Between Immune Responses and Atherothrombosis in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Cardiovascular events are major determinants of morbidity and mortality in systemic lupus erythematosus (SLE), particularly in patients with renal involvement. Although oxidative stress has been implicated in driving vascular and renal damage in SLE, the specific mechanisms remain unclear.

A Randomized, Placebo‐Controlled Trial of Hydroxychloroquine in Incomplete Lupus

Arthritis &Rheumatology, EarlyView.
Objective Patients with features of systemic lupus erythematosus (SLE) who do not fulfill classification criteria can be designated as incomplete lupus erythematosus (ILE). This condition includes individuals with a high risk of progression to SLE. Treatment of ILE may reduce symptoms, severity, and incidence of SLE.

Etanercept and venous thromboembolism: a case series

Journal of Medical Case Reports, 2010
Introduction The treatment with antitumor necrosis factor agents has often been associated with the induction of autoantibodies (antinuclear antibodies, anti-double stranded DNA antibodies and antiphospholipid antibodies).

Prothrombotic Activation of Platelet Pannexin 1 Channels in Antiphospholipid Syndrome

Arthritis &Rheumatology, Accepted Article.
Background ATP is released from platelets through both degranulation and pannexin‐1 (PANX1) channels. ATP then activates P2X receptors to amplify platelet activation via calcium‐dependent signaling. Objective To evaluate the role of platelet PANX1 channels in the pathophysiology of antiphospholipid syndrome (APS), an acquired thrombo‐inflammatory ...

Antiprothrombin Antibodies

Zdravniški Vestnik, 2015
In patients with the antiphospholipid syndrome (APS), the presence of a group of pathogenic autoantibodies called antiphospholipid antibodies causes thrombosis and pregnancy complications. The most frequent antigenic target of antiphospholipid antibodies
