What makes a good grant? Lots of things.... 1. Good grants: - are creative - fill gaps in our knowledge about a topic - tell a good story 2. Relevant to the goals of the funding agency (Not really that important here, but something to keep in mind) 3. Good grants are able to convince your peers to fund you - Must be well-written, clear, easy to read - Answers the “so what?” question
Reasons Reviewers Reject Proposals http://www.niaid.nih.gov/ncn/grants/write/write_d6.htm • Problem not important enough. • Study not likely to produce useful information. • Studies based on a shaky hypothesis or data. • Alternative hypotheses not considered. • Methods unsuited to the objective. • Problem more complex than investigator appears to realize. • Etc. • Etc. • Etc. • As the proposal is being assembled and drafted, look over these points on the website and ask yourself if any of them apply to your grant. • Grant reviews are partially subjective because everyone is biased toward certain techniques, experimental approaches and models.
Getting Started... What is your hypothesis? What biological question are you trying to address? What are your objectives? Are they clear? What are your main experimental approaches? Are they the most appropriate to meet your objectives?

Example: Research Plan Specific Aims Prolactin (PRL) is one of the most versatile hormones of mammalian organisms. Besides its role in lactation, secretion of PRL contributes to a wide range of physiological functions, i.e. adaptation to new environment (22), immune functions (23) osmoregulation (24,25), reproduction (26) and behavior (27). PRL of anterior pituitary origin is secreted by lactotrophs (28). Lactotrophs have spontaneously high secretory activity, which is controlled primarily by tonic inhibitory input of hypothalamic origin (29), though they receive stimulatory input, as well (29-31). The physiological PRL inhibiting factor is dopamine (DA) (32,33). DA is released from three, anatomically and functionally distinct hypothalamic neuroendocrine cell populations: I). periventricular hypothalamic dopaminergic (PHDA) neurons of the periventricular nucleus (A14), II) tuberohypophysial (THDA) and III) tuberoinfundibular (TIDA) neurons (34) of the arcuate nucleus (A12). PHDA and THDA neurons terminate in the intermediate and neural lobes of the pituitary gland, respectively (35,36). DA, released from THDA/PHDA terminals may reach the anterior lobe through the short portal vessels. On the other hand, TIDA neurons terminate in the external zone of the median eminence supplying the anterior pituitary gland with DA through the long portal vessels. Although the central role of TIDA neurons in hypothalamic control of PRL secretion is acknowledged, the relative contribution and importance of the distinct neuroendocrineDAergic neuron subpopulations to the regulation of PRL secretion is not understood.
Studies from our (37-39) and other (40-43) laboratories suggest that the daily activities of all three DAergicneuroendocrine neuron populations exhibit similar rhythmic changes (i.e. high in the morning, low in the afternoon). Although, the amplitudes of these rhythms of TIDA, THDA and PHDA populations are differentially modulated by ovarian steroids, the presence of rhythms is independent of the ovarian steroid background in female rats in all neuroendocrineDAergic neuron populations. Our CENTRAL HYPOTHESIS is that the rhythmic activity in all three populations of neuroendocrineDAergic neurons are paced by direct circadian input from the suprachiasmatic nucleus while its amplitude is modulated by interneuron-mediated input, ovarian steroid background, and PRL feedback from the pituitary gland. In this application, we will focus on the role of direct suprachiasmatic input, PRL feedback and signaling mechanisms in the generation of rhythmic patterns of DA release from the TIDA, THDA and PHDA by pursuing the following SPECIFIC AIMS:
To characterize the chronobiological and anatomical basis of regulatory mechanisms governing the rhythmic patterns of the DAergic input on PRL secretion. By conducting in vivo experiments in constant environments we will test whether the daily changes in the activities of neuroendocrineDAergic neuron populations are light entrained endogenous circadian rhythms. Tract tracing studies will be used to investigate the functional anatomical nature of the direct connection(s) between the circadian zeitgeber in the suprachiasmatic nucleus and the different neuroendocrineDAergic subpopulations. Antisense antagonism will be used to verify the functional significance of suprachiasmatic efferent fibers on the neuroendocrineDAergic neuron populations. To characterize the feedback role of PRL in the daily activity of PHDA, THDA and TIDA neurons. The incidence of PRL-Rs in the THDA and TIDA neurons is higher than in PHDA neurons, although PHDA neurons also express PRL-R in ovarian steroid-replaced rats. We suggest that PRL feedback is inherently part of the THDA and TIDA neurons’ circadian regulation and it is inducible in PHDA neurons by ovarian steroids. In order to verify this hypothesis, we will compare the effects of PRL on the activity of PHDA, THDA and TIDA neuron populations in ovariectomized and ovarian steroid-replaced rats. To identify the signal transduction mechanisms involved in the circadian regulation of the secretory activity of hypothalamic neuroendocrineDAergic neurons. We will identify the receptors, second messenger and cellular effector systems involved in mediating the effects of circadian input and PRL feedback on the neurosecretory activity of the PHDA, THDA and TIDA neuron subpopulations.
BACKGROUND AND SIGNIFICANCE • Provide just enough background information so the reviewer appreciates what you are proposing • Extraneous information is distracting • Compartmentalize information with bold headings, key words and sentences • Make copious use of diagrams and cartoons • Use a terminal sentence pointing to your goal at the end of each compartment
Fig. 1 The neuroendocrine DAergic neuron populations and their feedback regulation (Fig. 1) The hypothalamic A14 and A12 cell groups (Fig. 1), which are exclusively comprised of DAergic neurons (64,65) provide the pituitary gland with DA through two different routes: I) The tuberoinfundibular DAergic (TIDA) neurons send short projections to the external zone (EZ) of the median eminence. TIDA axons terminate on the basement membrane of the perivascular space surrounding the primary capillary loops of the portal system. From here the long portal vessels (LP) carry DA of TIDA origin to the anterior lobe (AL) of the pituitary gland. Perikarya of TIDA neurons show bimodal rostrocaudal distribution (66). The majority of TIDA neurons originate throughout the arcuate nucleus (ARN, A12), and a smaller population arises from the periventricular nucleus (PeVN, A14) (66). II) The tuberohypophysial DAergic (THDA) neurons of the rostral ARN (A12) and the periventricular hypothalamic (PHDA) neurons of the PeVN (A14) have long axons, which course through the pituitary stalk (PS) and terminate in the neural (NL) and intermediate(IL) lobes of the pituitary gland, respectively (35). Short portal vessels(SP) provide communication between the neurointermediate and the AL (Figure 1).
The terminal areas of the TIDA, THDA and PHDA axons are neurohemal zones, which lack the blood-brain barrier. The absence of the blood-brain barrier and the continuity between the pericapillary space and the liquor space are the anatomical bases for a free, most likely bi-directional communication between axon terminals and the blood-liquor space (67). While all three neuroendocrine neuron populations express PRL-Rs in female rats, the incidence of PRL-Rs on THDA and TIDA neurons is higher than in PHDA neurons (21). Changes in the ovarian steroid background and/or serum PRL levels differentially affect the abundance of PRL-R in the neuroendocrine DAergic neuron populations (21). Although to different extents, the activities ofTIDA (68,69), THDA and PHDA neurons are indeed affected by PRL in the peripheral blood (DeMaria, Lerant and Freeman, 1999, submitted). Of these neuroendocrine DAergic neuron populations, the autoregulatory properties of the PHDA neurons seem to most closely resemble the well-characterized nigrostriatal dopaminergic neurons as both nigrostriatal DAergic (70,71) and PHDA neurons (72) seem to be inhibited by D2/3–type DA (auto)receptors. There are data, however, indicating that TIDA neurons can be influenced by both D1 and D2 receptors, but the responses are different from that seen in nigrostriatal DAergic neurons (73). D2 receptor agonists were reported to stimulate TIDA neurons (74), while specific D1 agonists inhibit the reserpine- or neurotensin-evoked TIDA activation (75). We provide preliminary data demonstrating that D2 receptors do not colocalize with TIDA neuron terminals in the median eminence. This suggests that D2/3 receptors do not act as presynaptic autoreceptors on TIDA neurons. We will test our hypothesis that PRL provides the primary feedback in the THDA and TIDA neurons instead of D2/3 autoreceptors.

Example: Preparation of tissue for immunocytochemistry (ICC) Rats are sacrificed by an overdose of sodium pentobarbital, and perfused through a transcardial cannula with 50 ml of ice cold phosphate buffer (PBS, 0.1 M, pH 7.34, 295 mosm) immediately followed by 100 ml of ice cold fixative. The fixative applied usually is 4 % paraformaldehyde (PFA, in 0.1 M PBS, pH 7.5). The brains and pituitaries are postfixed for an hour in situ. After removal the brains and pituitaries are rinsed in PBS and immersed in 20% sucrose solution (in PBS, at 4ºC) until sinking. The tissue blocks are frozen on the freezing stage of a HM500OM cryostat (Zeiss, Germany). The brains are cut in 35-m coronal section between 300-4200 m post bregma and collected into 4 parallel series of free-floating sections. The sections are stored in cryoprotectant solution (133) until ICC is initiated. If the aforementioned tissue block does not contain an area with established immunoreactivity for the antigen in question, other areas of the brain (or other organs) are processed to provide positive and negative controls for the immunostaining. The pituitary glands are cut in 10-20 m coronal or horizontal sections, thaw-mounted on gelatin-subbed glass microscope slides and stored at -80ºC in closed tissue boxes containing Dryerite. Both the free floating brain sections and the mounted pituitary sections are thoroughly washed (5 X in PBS) prior to ICC. We have had ample experience with these techniques (21,37,38)

This is a revision of our previous application reviewed by the Biochemical Endocrinology (BCE) Study Section in October 1998. We have taken the reviewers’ critiques constructively and made the requested changes, which we believe, improved the current application. We thank the reviewers for providing insight into the shortcomings of our proposal. We have addressed each criticism below and have made appropriate changes in the text as indicated in Century Schoolbook font. • Response to Critique 1: • Criticism: The second question posed in Specific Aim I does not relate the changes in neuronal activity associated with the rhythm of water intake to the pharmacology of the DA receptor under investigation and no discussion of the effects of dehydration on food intake and other variables is presented. • Response: In agreement with the reviewer, we have eliminated the water deprivation experiments from this proposal.
Criticism: The rationale for use of unilateral versus bilateral injection sites of [biotinylated dextran] tracer is not apparent nor is the choice of a seven day waiting period following tracer injection justified. • Response: To answer the question of anatomical projection, unilateral injections will provide sufficient information. Also, it is easier to interpret the results of unilateral injections, since we cannot exclude the possibility of SCN efferents crossing the midline. The seven day survival period gives excellent results with the BDA-F tracer as shown by several laboratories (1-3). We now include these explanations and citations at the proposed experiments as well.
AND NOW…………. • You can do nothing more……. SO…… AWAIT THE AWARD NOTICE!!!!!!!
A final piece of advice... Do not wait until the week prior to the due date to write your grant proposal!
