Any process that modulates the activity of an enzyme.

Any process that modulates the rate or extent of the viral life cycle, the set of processes by which a virus reproduces and spreads among hosts.

The process whose specific outcome is the progression of the gonadal mesoderm over time, from its formation to the mature structure. The gonadal mesoderm is the middle layer of the three primary germ layers of the embryo which will go on to form the gonads of the organism.

Any process that modulates the frequency, rate or extent of development, the biological process whose specific outcome is the progression of an organism over time from an initial condition (e.g. a zygote, or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The process whose specific outcome is the progression of the larval heart over time, from its formation to the mature structure. In Drosophila the larval heart (dorsal vessel) is a continuous tube of mesodormal cells that runs beneath the dorsal midline of the epidermis, divided into an anterior aorta and a posterior heart proper.

Any process that modulates the frequency, rate or extent of behavior, the specific actions or reactions of an organism in response to external or internal stimuli.

Any process that modulates the frequency, rate or extent of the regulated release of insulin.

The rapid expansion of a T cell population following activation by an antigenic stimulus.

Any process involved in the replication of a retroviral genome. Retroviruses use RNA as their nucleic acid and reverse transcriptase to copy their genome into the DNA of the host cells chromosomes.

regulation of retroviral genome replication

Any process that modulates the frequency, rate or extent of retroviral genome replication.
