Case 59: Inhibition Of Enzymes Involved In Steroid Synthesis: Implications In Diabetes Treatment, Dr. Kathleen Cornely Nov 2022

Case 59: Inhibition Of Enzymes Involved In Steroid Synthesis: Implications In Diabetes Treatment, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

Drugs used to increase insulin sensitivity may also inhibit enzymes involved in steroid synthesis. Prior to this investigation, it was uncertain whether the drugs inhibited the enzymes directly or whether the decrease in androgen synthesis observed during treatment was a secondary effect.


Case 71: Lactate Dehydrogenase As A Therapeutic Target To Treat Parasitic Disease, Dr. Kathleen Cornely Mar 2022

Case 71: Lactate Dehydrogenase As A Therapeutic Target To Treat Parasitic Disease, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

In this case study, researchers use their knowledge of lactate dehydrogenase in parasites and humans to investigate inhibitors that are selective for the parasite agent.


Case 51: Purification Of A Transferase Involved In The Production Of Physiologically Important Glycoproteins, Dr. Kathleen Cornely Jul 2021

Case 51: Purification Of A Transferase Involved In The Production Of Physiologically Important Glycoproteins, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

A transferase involved in post-translational glycosylation of a physiologically important glycoprotein is purified and characterized.


Case 40: A Collection Of Collagen Cases, Dr. Kathleen Cornely Jul 2021

Case 40: A Collection Of Collagen Cases, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

Factors important in the stability of collagen are examined.


Case 6: Hemoglobin Providence, Dr. Kathleen Cornely Jul 2021

Case 6: Hemoglobin Providence, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

A mutant hemoglobin variant, Hemoglobin Providence, exists in two forms in vivo.


Case 32: Inhibition Of Protein Tyrosine Phosphatase Enzymes As A Possible Treatment For Diabetes, Dr. Kathleen Cornely Mar 2021

Case 32: Inhibition Of Protein Tyrosine Phosphatase Enzymes As A Possible Treatment For Diabetes, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

Protein tyrosine phosphatases (PTPs) are investigated because of their ability to reverse the effects of protein tyrosine kinases (PTKs). Inhibitors of the PTP investigated in this study have insulin-mimetic effects and have potential in the treatment of diabetes.


Case 70: Hemoglobin Mito: A Japanese Hemoglobin Variant With Altered Oxygen Binding Affinity, Dr. Kathleen Cornely Feb 2021

Case 70: Hemoglobin Mito: A Japanese Hemoglobin Variant With Altered Oxygen Binding Affinity, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

In this case study, researchers use their knowledge of hemoglobin structure to predict the oxygen binding properties of a hemoglobin mutant with a single amino acid substitution, then test their hypothesis by studying the mutant’s oxygen binding properties.


Case 34: Kinetics Of Alkaline Phosphatase, Dr. Kathleen Cornely Jan 2020

Case 34: Kinetics Of Alkaline Phosphatase, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

Kinetic studies are carried out using the alkaline phosphatase, an enzyme that has an important role in skeletal mineralization.


Case 67: Phenylalanine Hydroxylase: An Investigation Of Its Structure Leads To The Development Of Pku New Therapies, Dr. Kathleen Cornely Nov 2019

Case 67: Phenylalanine Hydroxylase: An Investigation Of Its Structure Leads To The Development Of Pku New Therapies, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

The characteristics of phenylalanine hydroxylase, the enzyme missing in persons afflicted with the genetic disorder phenylketonuria (PKU), are examined. Understanding how the enzyme works will allow the development of drugs to treat this condition.


Case 64: Alkalosis In A Patient With A Brain Tumor: A Link Between The Cns And Blood Ph, Dr. Kathleen Cornely Sep 2019

Case 64: Alkalosis In A Patient With A Brain Tumor: A Link Between The Cns And Blood Ph, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

The response of the carbonic acid/bicarbonate buffering system to a patient’s hyperventilation–presumably caused by CNS abnormalities following surgery to remove a brain tumor–is examined.


Case 61: Inhibition Of Malarial Aspartate Protease, Dr. Kathleen Cornely Jan 2019

Case 61: Inhibition Of Malarial Aspartate Protease, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

In this case study, students investigate the purification and kinetic properties of a malarial asparate protease.


Case 62: Glycolysis, The Pentose Phosphate Pathway, And The Citric Acid Cycle In Tumorigenesis, Dr. Kathleen Cornely Nov 2015

Case 62: Glycolysis, The Pentose Phosphate Pathway, And The Citric Acid Cycle In Tumorigenesis, Dr. Kathleen Cornely

Chemistry & Biochemistry Case Studies

Hypoxia-inducible factors are transcription factors that mediate the cellular response to hypoxia (low cellular oxygen concentration) by enhancing or suppressing the transcription of specific genes involved in metabolic pathways.
