       Transcriptional Phenomenon 1

 Repression of KCNA5 gene in pulmonary arterial hypertension condition [1]

TF Protein Name

 Hypoxia-inducible factor 1-alpha Transcription Factor Info

Studied Phenotype

 Pulmonary arterial hypertension [ICD11: BB01.0]

Tissue

 Lung

Related DT Changes

 Down regulating

Experimental Material

 Sprague-Dawley rats

Detailed Description

 Hypoxia-inducible factor 1-alpha (HIF1A) has been reported to repress the transcription of KCNA5 gene in pulmonary arterial hypertension condition, which leads to a decreased expression of the drug transporter Voltage-gated potassium channel subunit Kv1.5.

TF Superclass 3: Helix-turn-helix domains

      Class 3.4: Heat shock factors

       Transcriptional Phenomenon 1

 Activation of KCNA5 gene in cervical cancer condition [2]

TF Protein Name

 Heat shock factor protein 1 Transcription Factor Info

Studied Phenotype

 Cervical cancer [ICD11: 2C77]

Tissue

 Cervix

Related DT Changes

 Up regulating

Experimental Material

 Human human papillomavirus-related endocervical adenocarcinoma cells (HeLa)

Detailed Description

 Heat shock factor protein 1 (HSF1) has been reported to activate the transcription of KCNA5 gene in cervical cancer condition, which leads to an increased expression of the drug transporter Voltage-gated potassium channel subunit Kv1.5.
