Biology at TWU

Welcome to the TWU Biology Department.

Our mission is to promote understanding of the processes of life, its evolution, and its diversity and to prepare students for careers or advanced graduate/professional training in biological sciences.

We are delighted to have you look over our programs and perhaps choose us for your academic career.

Dr. Sarah A. McIntire

Friends and Colleagues, 

A Memorial Service honoring the life of Dr. Sarah A. McIntire will be hosted at TWU’s Denton campus on Tuesday July 19, 2016 from 3-4:30 pm.  The event will be held at the Ann Stuart Science Complex in the Atrium and is supported by the TWU Biology Department. 

Music will be provided by the TWU Department of Music.  Individuals who were close to Dr. McIntire will be offering comments and sharing memories.



A power point presentation with pictures, accomplishments and accolades for Dr. McIntire will be available for viewing in ASSC 153 along with the guest book.




Please direct all of your questions to Nani Cooper at Directions provided upon request.

We congratulate the following:

  • Recipients of the 2016 Summer Research Initiative:

                Dr. Dayna Averitt, “Sex Differences in Serotonergic Modulation of Trigeminal Nociceptors”

                Dr. Christopher Brower, “A Possible Link between Protein Degradation and Gene Expression”

 • Ph. D candidates Sumod Sebastian and Remya A. Veettil for winning the Howard J. Arnott Student Competition Award at the Spring 2016 Texas Society for Microscopy meeting for their presentation: “Role of dynamin and caveolae in the endocytosis of surface functionalized nanospheres in neurons and neuron like cells.” Sumod Sebastian, Remya A. Veettil, Thomas McAllister, Santaneel Ghosh and DiAnna Hynds.

Dr. Michael Bergel for his distinction of having the cover of The Journal of Biological Chemistry February 12th, 2016, issue. Sincere gratitude is expressed to Ph.D Candidate Sanil Sansar (Hynds Lab) for his expertise in creating the cover art.

• In addition, please take note of the peer reviewed work published in the same issue: “Mitotic Activation of a Novel Histone Deacetylase 3-Linker Histone H1.3 Protein Complex by Protein Kinase CK2.” Hemangi Patil, Carrie Wilks, Rhiannon Wold Gonzalez, Sudheer Dhanireddy, Heather Conrad-Webb, and Michael Bergel. JBC Papers in Press, DOI 10.1074/jbc.M115.643874

The symbolic mitotic spindle fibers, composed of confocal microscopy images, demonstrate the colocalization of HDAC3 and H1.3 proteins to the polar microtubules and to the spindle poles in HeLa cells during various mitotic stages. The antibodies used for the indirect immunofluorescence staining were: anti-HDAC3 (green), anti-histone H1.3 (red), anti-Eg5 (polar microtubules motor protein) (green/red), and the DNA stain—Hoechst (blue).

  • 2016 New Investigator Research Enhancement Program:
    • Dr. Dayna Averitt, Effects of Estrous Cycle on Trigeminal Pain
    • Dr. Christopher Brower, TDP43 Toxicity and Its Degradation by the N-end Rule Pathway to Prevent Neurodegeneration
    • Dr. Tina Gumienny, Determining the Roles of Three Cellular Trafficking Regulators in TGF-beta Signal Regulation
