Engineered Plga Nanoparticles For Delivery Of Sirna In Mcf-7 Breast Cancer Cells, Sydney Pong, Samit Shah, Vivek Gupta
Engineered Plga Nanoparticles For Delivery Of Sirna In Mcf-7 Breast Cancer Cells, Sydney Pong, Samit Shah, Vivek Gupta
Student Scholar Symposium Abstracts and Posters
Small interfering RNAs have been an emerging medical treatment for molecular based diseases as they are capable of gene-specific knockdown. Appropriate and efficient delivery remains one of the biggest challenges in the development of siRNA as an anti-cancer treatment. Nanoparticles containing siRNA were characterized and the efficacy of various peptides in the transfection of the nanoparticles were tested. A gene silencing assay was developed in order to determine the effect of siRNA therapeutics on gene functionality in breast cancer cells.

The past few years television, podcasts, and blogs across the Internet promoted the role of DNA testing in genealogy. But what do you really get, and is it worth the price? We discuss the logistics of DNA testing as it relates to genealogy and take a hard look at the legal issues involved in genealogy’s hottest topic.

The shortage of molecular information on cell cycle changes along embryonic stem cell (ESC) differentiation prompts an in silico approach, which may provide a novel way to identify candidate genes or mechanisms acting in coordinating the two programs. We analyzed germ layer specific gene expression changes during the cell cycle and ESC differentiation by combining four human cell cycle transcriptome profiles with thirteen in vitro human ESC differentiation studies. To detect cross-talk mechanisms we then integrated the transcriptome data that displayed differential regulation with protein interaction data. A new class of non-transcriptionally regulated genes was identified, encoding proteins which interact …

A Disintegrin And Metalloproteinase with ThromboSpondin motifs16 (ADAMTS-16) is a member of a family of metalloproteinases. Using a novel zinc-finger nuclease based gene-edited rat model harboring a targeted mutation of the Adamts16 locus, we previously reported this gene to be linked to blood pressure regulation. Here we document our observation with this model that Adamts16 is essential for normal development of the testis. Absence of Adamts16 in the homozygous Adamts16(mutant) males resulted in cryptorchidism and male sterility. Heterozygous Adamts16(mutant) males were normal, indicating that this is a recessive trait. Testes of homozygous Adamts16(mutant) males were significantly smaller with significant histological …

Pseudomonas aeruginosa is a Gram negative, opportunistic pathogen that uses the overproduction of alginate, a surface polysaccharide, to form biofilms in vivo. Overproduction of alginate, also known as mucoidy, affords the bacterium protection from the host's defenses and facilitates the establishment of chronic lung infections in individuals with cystic fibrosis. Expression of the alginate biosynthetic operon is primarily controlled by the alternative sigma factor AlgU (AlgT/σ22). In a nonmucoid strain, AlgU is sequestered by the transmembrane antisigma factor MucA to the cytoplasmic membrane. AlgU can be released from MucA via regulated intramembrane proteolysis by proteases AlgW and MucP causing the …

Circadian rhythms, or the 24-hour biological cycles of living cells, function as the body’s internal clock. Although circadian rhythms and sleep are very different processes, they are closely related to one another as these cycles play an important role in sleeping and waking patterns. Recent studies have shown that lack of sleep or sleep of poor quality can disrupt circadian rhythms and may actually cause cognitive disorders and memory loss, facilitate false memory production, and even alter gene expression in humans. This literature review is focused on identifying the epigenetic and physiological effects of disruptions and desynchronization in circadian rhythms …

A doença Renal Policística Autossômica Dominante (DRPAD) é causada por mutações em um de dois genes, PKD1 ou PKD2, que resultam em acúmulos de cistos nos rins. O objetivo deste trabalho foi verificar a existência de possíveis associações entre variantes em genes de citocinas e em receptores de citocinas para as posições IL1A-889 (rs1800587), IL1B-511, +3962 (rs16944, rs1143634), IL1R1970 (rs2234650), IL1RA11100 (rs315952), IL4RA+1902 (rs1801275), IL12-1188 (rs3212227), IFNG+874 (rs2430561), TGFB1códon 10, códon 25 (rs1982073, rs1800471), TNF-308, -238 (rs1800629, rs361525), IL2-330, +166 (rs2069762, rs2069763), IL4-1098, -590, -33 (rs2243248, rs2243250, rs2070874), IL6-174, nt565 (rs1800795, rs1800797) e IL10-1082,-819,-592 (rs1800896, rs1800871, rs1800872) e a DRPAD. …
Retinoic Acid Regulation Of Thyroid Hormone Action In Bone Cells, Anjali Babbar
Retinoic Acid Regulation Of Thyroid Hormone Action In Bone Cells, Anjali Babbar
Loma Linda University Electronic Theses, Dissertations & Projects
Retinoic acid and thyroid hormone are known to play key roles in the regulation of endochondral ossification. However, the issue of whether these two hormones interact with each other to regulate bone functions remains to be established. We investigated how thyroid hormone and retinoic acid interact to regulate cells involved in endochondral bone formation. We demonstrate that thyroid hormone treatment stimulates differentiation of ATDC5 chondrocytes and promotes formation of mineralized nodules while retinoic acid treatment at high dose inhibits chondrocyte differentiation and formation of mineralized nodules. Furthermore, thyroid hormone induced mineralized nodule formation is inhibited by co-treatment with retinoic acid …

Most association studies focus on disease risk, with less attention paid to disease progression or severity. These phenotypes require longitudinal data. This paper presents a new method for analyzing longitudinal data to map genes in both population-based and family-based studies. Using simulated systolic blood pressure measurements obtained from Genetic Analysis Workshop 18, we cluster the phenotype data into trajectory subgroups. We then use the Bayesian posterior probability of being in the high subgroup as a quantitative trait in an association analysis with genotype data. This method maintains high power (>80%) in locating genes known to affect the simulated phenotype …

Male infertility is typically diagnosed upon routine semen analysis following the World Health Organisation’s (WHO) semen analysis manual. Recent editions of the manual have essentially changed the diagnosis of a semen sample, prompting debate between experts as to which edition should be followed. Deoxyribonucleic Acid (DNA) integrity analysis is proving to be a useful adjunct to semen analysis as 15% of infertile men have a normal semen analysis but they have an increased DNA fragmentation level (DFL) which has been associated with increased disease incidence in any resultant offspring. However, such tests are not endorsed by the WHO, possibly due …
