Somatic cell lineage is required for differentiation and not maintenance of germline stem cells in Drosophila by: There is evidence that the Aryl hydrocarbon receptor (AHR) plays an important role in normal development and cancerogenesis [1,2,3,4,5,6,7,8,9,10,11,12,13,14].A proper concentration of activated AHR is important for cell survival and organism functioning [15,16,17,18,19].Ligand binding is critical for AHR activation, because after the binding it moves to the nucleus, dimerizes with the Aryl Author: Angelina A.

Description Of A Traffic Jam Scene. News. Bangkok's traffic problem has been getting worse since the government introduced a policy to refund tax for first-time car buyers. Coupled with the Thai aspiration to own a car and get some status, this policy has resulted in five million vehicles in a city which can only cope with less than two million cars.   Journal of Cell Science Article; Info & metrics Sadly, this edition of Essays in Biochemistry on Molecular Trafficking is not going to improve matters: neither Blobel nor his seminal hypothesis are mentioned in the chapter on protein translocation into the endoplasmic reticulum (ER). Altogether, this book is a useful Author: Robin C. May.

Downloadable (with restrictions)! Area-wide traffic jams develop through the propagation of queues from link to link, a process that resembles the growth of branches on a tree. The process is not well understood. In this paper, simple models for jam growth arising from a single bottleneck are developed for an idealized grid network. Under these idealized conditions, it has been shown that. Traffic-like collective movements are observed at almost all levels of biological systems. Molecular motor proteins like, for example, kinesin and dynein, which are the vehicles of almost all intra-cellular transport in eukayotic cells, sometimes encounter traffic jam that manifests as a disease of the organism. Similarly, traffic jam of collagenase MMP-1, which moves on the collagen fibrils Cited by: 2.

A Molecular and Phenotypic Analysis of traffic jam, a Key Regulator of Gonad Morphogenesis by providing reagents which were invaluable in the molecular and phenotypic analysis of trafic jant: TJ is a key regulator of gonad morphogenesis REFERENCES vii.

LIST OF FIGURES Fig. Here we show that the gene traffic jam (tj) produces a soma-specific factor that controls gonad morphogenesis and is required for female and male by: Here we show that the gene traffic jam (tj) produces a soma-specific factor that controls gonad morphogenesis and is required for female and male fertility.

tj encodes the only large Maf factor in. A molecular and phenotypic analysis of traffic jam, a key regulator of gonad morphogenesis [microform]. In Drosophila ovarian somatic cells, piRNAs derived from the 3′ UTR of Traffic jam have been proposed to target Fas3, suggesting a connection between Piwi and silencing of the Fas3 gene Saito et al., Cited by: Possible mechanisms underlying traffic jam formation and propagation are presented from a dynamical viewpoint.

Stable and unstable motions are described that may give the skeleton of traffic dynamics, and the effects of driver behaviour are emphasized in determining the emergent state in a vehicular by:   They discovered that a significant population of these piRNAs map uniquely to the 3′UTR of a follicle cell–specific gene called traffic jam (tj).

Remarkably, we show that ectopic expression of a single gene in the somatic ovarian cells, the translational repressor and key regulator of germline fate nanos, is largely responsible for aberrant development.

Using a genetic approach, we find that in the ovary L(3)mbt function requires its co-factor Lint-1 but is independent of the dREAM by: 5. The cellular secretory pathway is important for plant immunity for active defense against potential pathogens.

17 By contrast, invasive pathogens have evolved a means to use these trafficking pathways for the suppression of plant defenses and for the benefit of microbial proliferation.

In fact, the large Maf transcription factor Traffic Jam, which is required for proper interactions between the germline and soma, regulates the expression of E‐cadherin but not N‐cadherin in the FCs (Li et al., ).

We identified an interconnected network of TFs that play an important role in the maintenance and differentiation of both germline and somatic cell populations, signal processing V-ATPase proton pumps, and nuclear-transport-engaged Nups as regulators in the Drosophila male stem cell system.
