Objective: To look at the role of inhibin and activin in predicting pregnancy outcome in patients with history of recurrent miscarriage.
Design: Observational clinical study.
Setting: Recurrent miscarriage clinic of a tertiary care teaching hospital.
Patient(s): Patients with history of recurrent miscarriage.
Intervention(s): Serial serum inhibin A and activin A concentrations were measured in weeks 5 though 8 of pregnancy.
Main Outcome Measure(s): Serum concentrations of inhibin A and activin A levels.
Result(s): Mean inhibin A concentration at 5 to 6 weeks for women who miscarried and those who had live births was 33 and 51 pg/mL, respectively; activin A at same gestation for the two groups was 534 and 643 pg/mL, respectively. After 2 weeks, mean inhibin A concentration for women who miscarried and those who had live births was 66 and 145 pg/mL, respectively, and activin A was 747 and 1,123 pg/mL, respectively.
Conclusion(s): It is possible that inhibin A and activin A may be used as markers to predict pregnancies that are likely to miscarry.

Inhibin, β, which is also known as INHBA, encodes a protein that belongs to the Transforming Growth factor-β (TGF-β) superfamily, which plays a pivotal role in cancer. Gastrointestinal tract (GI tract) cancer refers to the cancers that develop in the colon, liver, esophagus, stomach, rectum, pancreas, and bile ducts of the digestive system. The role of INHBA in all GI tract cancers remains understudied.

Article Synopsis
- The study addresses the urgent need for reliable biomarkers in colorectal cancer (CRC) diagnosis, highlighting limitations in current methods and the potential for novel, non-invasive solutions.
- Using advanced genomic and proteomic technologies, researchers identified five promising biomarkers: INHBA, MMP7, PSAT1, SLC7A5, and TGFBI, which showed significantly higher expression levels in CRC patients compared to healthy controls.
- The biomarkers demonstrated strong diagnostic accuracy, with AUC values between 0.8361 and 0.9869, suggesting they could greatly improve early detection and precision in CRC diagnostic practices.

Activins and inhibins, members of the transforming growth factor β (TGFβ) superfamily, were initially recognized for their opposing effects on the secretion of follicle-stimulating hormone. Subsequent research has demonstrated their broader biological roles across various tissue types. Primarily, activins and inhibins function through the classical TGFβ SMAD signaling pathway, but studies suggest that they also act through other pathways, with their specific signaling being complex and context-dependent.

Objective: Gastric cancer (GC) is characterized by its high malignancy and poor prognosis. However, the role of Inhibin subunit beta A (INHBA) in GC remains insufficiently understood. This study aims to comprehensively evaluate the clinical significance, biological roles, and possible mechanisms of INHBA in GC.
